How we researched this list

For each tool in this category we ran a live keyword research pass: real Google results (page 1 and page 2), the questions those pages answer, and the social discussion around the topic. Every page we could open was measured — content length, number of questions answered, FAQ presence and image count. Pages that blocked access are recorded as blocked rather than guessed at.

Across this category the sites that currently rank are: calculator.net, calculatorsoup.com, ilovepdf.com, smallpdf.com, omnicalculator.com, adobe.com, canva.com, thecalculatorsite.com, freeconvert.com, unitconverters.net.

Why in-browser matters

Most tool sites upload your file to a server, queue it, and often ask for an account before letting you download the result. Toolfyra's tools run entirely on your device: the work happens in the browser tab, so there is nothing to upload, nothing to wait for, and nothing stored about you.

Frequently asked questions

Are these text tools tools really free?

Yes. All 32 tools in this category are free with no usage limit, no watermark and no account. Toolfyra does not gate any tool behind a sign-up or a paywall.

Do I have to upload my files?

No. Every tool processes your input in the browser using standard web APIs. You can verify this in your browser's network tab — no file is sent to a server.

Do they work on mobile?

Yes. The layout is mobile-first and works in Chrome, Safari, Firefox and Edge on Android and iPhone.

What do people most often ask about fancy text generator?

A common question is "How can I generate fancy text?" — the short answer is that the tool runs locally, so it works offline after first load and never stores your input.

FAQ answers: https://toolfyra.com/llms-full.txt - Content updated continuously; this file regenerates on every deploy (last: 2026-09-03). ive makers use decimal TB (10¹² bytes); your OS shows binary TiB (2⁴⁰) and labels it TB. 1 TB = 0.909 TiB — hence 931 'GB'. Q: MB vs MiB? A: MB = 10⁶ bytes (decimal), MiB = 2²⁰ = 1,048,576 bytes (binary) — both here. Q: Bits vs bytes? A: 8 bits = 1 byte — internet speeds are bits (Mb), file sizes are bytes (MB): divide speed by 8 for real MB/s. Q: Download time estimate? A: Convert your file to megabits, divide by your Mbps speed — or just remember: 100 Mbps ≈ 12.5 MB/s. Q: Offline? A: Yes. Q: Why 1024 vs 1000 matters? A: Historical computing used 2¹⁰=1024; storage industry standardized 10³=1000 — the tool supports both honestly. ## Pressure Converter URL: https://toolfyra.com/pressure-converter.html Category: Calculators Free pressure converter: PSI to bar, kPa, atmospheres, mmHg/Torr, mbar — exact factors, instant, offline. Tyre gauges say PSI, European manuals say bar, weather maps say hPa, blood pressure says mmHg. One tool, exact factors (1 bar = 100,000 Pa; 1 atm = 101,325 Pa), live conversion. Q: What PSI is 2.2 bar? A: 2.2 × 14.5038 = 31.9 PSI — type it and see, car-tyre accurate. Q: mmHg vs Torr? A: Practically identical (0.017 ppm apart) — both included. Q: Weather hPa? A: hPa = mbar exactly; 1013 hPa = standard sea-level pressure. Q: Diving? A: 1 atm per 10 m of seawater is the dive-school rule; convert gauge readings exactly here. Q: Offline? A: Yes. Q: Which for bike tyres? A: Road bikes ~5–8 bar (70–115 PSI) — convert your gauge's scale here. ## Cooking Measurement Converter URL: https://toolfyra.com/cooking-converter.html Category: Calculators Free cooking converter: cups to grams and ml, tablespoons, teaspoons, fluid ounces — US and metric, recipe-safe. Baking is chemistry: the wrong cup size or a packed-vs-level tablespoon ruins it. This converter keeps US (240 ml) and metric (250 ml) cups separate, includes tbsp/tsp/fl-oz, and — for common ingredients — volume-to-weight hints, all offline. Q: Is a cup 240 or 250 ml? A: US recipes = 240 ml; metric-system recipes = 250 ml — this tool labels both so you match your recipe's origin. Q: Cups to grams for flour? A: Volume-to-weight depends on the ingredient (1 US cup flour ≈ 120–130 g, sugar ≈ 200 g) — use a kitchen scale for baking precision. Q: Tablespoon size? A: US tbsp = 14.8 ml, Australia = 20 ml — US is used here, labeled clearly. Q: Butter sticks? A: 1 US stick = 1/2 cup = 113 g — convert cups here, weigh 113 g per stick. Q: Offline in kitchen? A: Yes — works with no signal. Q: Why do recipes differ by country? A: Different cup/pint standards — the tool names the standard so nothing is ambiguous. ## Shoe Size Converter URL: https://toolfyra.com/shoe-size-converter.html Category: Calculators Free shoe size converter: US to UK, EU and centimeters for men, women and kids — instant, offline, shopping-safe. International shoe shopping lives or dies on size charts — and they differ by gender and region. This converter separates Men/Women/Kids tables and converts US ⇄ UK ⇄ EU ⇄ foot-length (cm/heels) instantly, with an honest note that brands vary and you should measure your foot in cm for the final check. Q: Is US 9 the same for men and women? A: No — women's US sizes run ~1.5 higher: women's 9 ≈ men's 7.5. Pick the right table first. Q: How do I measure my foot in cm? A: Stand on paper, mark heel and longest toe, measure — cm is the most reliable cross-brand reference. Q: Do EU sizes match across brands? A: Approximately only — EU sizing is unregulated; when between sizes, size up for sneakers. Q: Kids' sizes? A: Separate kids table (US K, UK child, EU) included. Q: Nike/Adidas differences? A: Brands vary up to half a size — use cm as the tie-breaker on each brand's own chart. Q: Works offline? A: Yes — even in the fitting room. ## Discount Calculator URL: https://toolfyra.com/discount-calculator.html Category: Money & Business Free discount calculator: price minus percent off, plus tax option, double discounts (20% then 10%) and final savings — instant. Sales live on confusion: '30% + extra 20%' is NOT 50% off. This calculator gives the final price, the total saving, and the real combined percentage of stacked discounts — so you never fall for fake markdowns. Q: Does 20% + 10% equal 30% off? A: No — stacking multiplies: 20% then 10% = 28% total. The tool shows the real number. Q: Tax before or after discount? A: Most countries tax the discounted price — the calculator follows that standard. Q: Can I compute the original price from a sale price? A: Reverse it: sale ÷ (1 − discount%) — divide on this page's input, or ask and we'll add a reverse mode. Q: Is 50% off + 50% off = free? A: Never — it's 75% off. See it live on this page. Q: Works with any currency? A: Yes — math is currency-agnostic; ignore the $ symbol or treat it as your symbol. Q: Black-Friday honest check? A: Compare the shown final price with the item's 30-day history — tools like CamelCamelCamel help; this calculator gives the math part instantly. ## Markup Calculator URL: https://toolfyra.com/markup-calculator.html Category: Money & Business Free markup calculator: cost + markup % = selling price, with gross margin % — and the markup-vs-margin difference explained. Markup and margin are different numbers that salespeople mix up daily: 50% markup = 33.3% margin. Enter your cost and markup, get the selling price, profit per unit and the honest margin % — with the formula shown. Q: Markup vs margin? A: Markup = profit ÷ cost; margin = profit ÷ price. 100% markup = 50% margin — the tool shows both. Q: What markup should I use? A: Retail commonly 50–100%; groceries 5–25%; services 60%+ — cover costs + market reality. Q: Price with 30% margin? A: Price = cost ÷ (1 − 0.30) — the tool computes it if you enter markup 42.86%. Q: Include fees? A: Add platform/payment fees into your cost first for true pricing. Q: Currency? A: Any — math is currency-neutral. Q: Bulk discounts? A: Compute each tier's price here, keep margins honest per tier. ## ROI Calculator URL: https://toolfyra.com/roi-calculator.html Category: Money & Business Free ROI calculator: gain minus cost over cost, plus annualized ROI for multi-year investments — instant and clear. ROI answers one question: was it worth it? This calculator gives the basic formula ((gain−cost)/cost), and — the part most calculators skip — the annualized ROI that makes a 3-year 60% return comparable to a 1-year 25% return. Q: What is a good ROI? A: Depends on risk: S&P-500 historically ~10%/year; compare your annualized figure against that baseline. Q: Why annualized? A: 60% over 3 years ≈ 16.9%/year — without annualizing you can't compare investments of different lengths. Q: Does it include fees? A: Include every cost in 'cost' — honest ROI includes fees, taxes and time. Q: Negative ROI? A: Shown honestly — that's information. Q: Real estate/stocks/crypto? A: The math is identical — enter cost and final value. Q: Currency? A: Any. ## CAGR Calculator URL: https://toolfyra.com/cagr-calculator.html Category: Money & Business Free CAGR calculator: beginning value, ending value, years → exact compound annual growth rate + total growth. CAGR is the number serious investors quote: the constant yearly rate that would take you from start to end. The tool uses the exact formula (end/start)^(1/years)−1 and also shows total growth for context. Q: What is CAGR in one line? A: The fixed %/year that links start to end as if growth were smooth. Q: CAGR vs average return? A: Average of yearly returns misleads (+50%, −50% averages to 0 but you lost 25%); CAGR tells the truth. Q: Negative ending value? A: CAGR needs positive values — for losses use the ROI calculator. Q: Revenue CAGR? A: Same math — investors, startups and markets all use it. Q: Fractional years? A: Yes — decimals supported (2.5 years fine). Q: Currency? A: Any — ratios are currency-neutral. ## Simple Interest Calculator URL: https://toolfyra.com/simple-interest-calculator.html Category: Money & Business Free simple interest calculator: P × R × T computed instantly with total amount — plus when simple beats compound. Simple (flat) interest is what car dealers, personal notes and many short loans actually use — NOT the compound math most calculators assume. This one uses the exact simple formula and shows total payable. Q: Simple vs compound? A: Simple pays interest only on the principal; compound pays on interest too — simple is cheaper for borrowers. Q: Rate per year? A: Yes — enter annual %; the tool handles fractional years too. Q: Months instead of years? A: Enter years as decimals (18 months = 1.5). Q: Where is simple interest used? A: Auto loans, personal IOUs, bonds coupons, short-term notes. Q: Currency? A: Any. Q: Why is my bank charging more? A: Their quote may be compound or add fees — ask for the APR breakdown; compute simple here for comparison. ## Break-Even Calculator URL: https://toolfyra.com/break-even-calculator.html Category: Money & Business Free break-even calculator: fixed costs, price, variable cost → break-even units and revenue, with margin per unit. Every business plan lives or dies here: Break-even units = fixed costs ÷ (price − variable cost). The tool also shows contribution margin per unit and the revenue figure — the three numbers every founder should know cold. Q: What if price minus variable cost is zero or negative? A: You can never break even at that price — the tool says so honestly; raise price or cut unit costs. Q: Include salaries? A: Yes — salaries, rent, software: everything that doesn't vary per unit goes in fixed costs. Q: Break-even revenue? A: Shown — useful when units don't apply (services). Q: Multiple products? A: Run each product separately; blended analysis needs weighted averages. Q: Currency? A: Any. Q: Why is my real break-even later? A: Reality adds irregular costs — revisit monthly; the model is a compass, not a contract. ## Running Pace Calculator URL: https://toolfyra.com/pace-calculator.html Category: Health & Fitness Free running pace calculator: distance and finish time gives pace per km/mile, speed, and 10K/half predictions — instant. Training plans speak pace, treadmills speak speed, watches speak both. This calculator converts your goal into the numbers your run needs — plus honest Riegel-formula predictions for other race distances. Q: What pace for a 25-minute 5K? A: 5:00 min/km (8:03 min/mile) — enter it and see. Q: How accurate are predictions? A: Riegel formula is good when training matches the distance — a target, not a promise. Q: Treadmill speed? A: The speed readout converts directly. Q: Walking? A: Identical math — pace is pace. Q: GPS drift? A: Pace from known distances (race/track) beats GPS jitter — compute after the race. Q: Mobile? A: Yes — big touch inputs, works offline. ## Heart Rate Zone Calculator URL: https://toolfyra.com/heart-rate-zones.html Category: Health & Fitness Free heart-rate zone calculator: Tanaka max HR, resting-HR Karvonen option, all 5 training zones in BPM. Zone training works only if your zones are right. This tool computes max HR (Tanaka formula: 208 minus 0.7 times age — more accurate than the old 220-age), refines with your measured resting HR via the Karvonen method, and lays out Z1 to Z5. Q: Which max-HR formula? A: Tanaka (208 - 0.7 x age) fits real populations better than 220-age. Q: Why resting HR? A: Karvonen zones track your working range — more personal than percent-of-max alone. Q: Zone 2? A: Easy aerobic base — full-sentence talk; see its BPM range here. Q: Watch vs this? A: Watches estimate; this computes from your inputs. Q: Medication? A: Beta-blockers change HR — seek medical guidance; this is general info. Q: Update? A: Resting HR drops with fitness — re-enter monthly. ## Calories Burned Calculator URL: https://toolfyra.com/calories-burned-calculator.html Category: Health & Fitness Free calories-burned calculator: weight x activity MET x time — walking, running, cycling, gym, sports, chores — honest numbers. Fitness machines famously overestimate burn. This calculator uses Compendium of Physical Activities MET values — the research standard — with the exact formula: kcal = MET x 3.5 x kg x hours / 200. Honest numbers, wide activity list, live updates. Q: What is MET? A: Metabolic Equivalent: 1 MET = resting burn; running is about 10 METs = 10x resting. Q: Treadmill shows more? A: Machines count gross calories and flatter you — MET x weight is the honest net. Q: Which values? A: Standard compendium METs, shown next to each activity. Q: Weight-loss math? A: 7,700 kcal is about 1 kg fat — pair with a deficit, do not eat back every burned calorie. Q: Accuracy? A: 10-20% individual variation — a compass, not a lab. Q: Medical note? A: General estimate, not medical advice. ## Reverse Text Generator URL: https://toolfyra.com/reverse-text.html Category: Text Tools Free reverse text: reverse letters, word order or lines — instant, offline, copy in one tap.

No signup, no upload — honest results. Most 'free plagiarism checker' pages run the same trick behind the curtain: they query a search index per sentence and show you matches. We do it in the open, against named public sources: OpenAlex (every scholarly work with an open record), Crossref (official DOI metadata) and Wikipedia. Every flagged sentence links to its source so you can verify it yourself. If a source is unreachable, we tell you instead of hiding it. That is what an honest originality check looks like — and your text never leaves your browser except as short search queries over HTTPS. Q: Is this plagiarism checker really free? A: Yes — no signup, no word limit on the page, no premium unlock. The check runs in your browser against free official APIs (OpenAlex, Crossref, Wikipedia). Q: Which sources does it check? A: OpenAlex (250M+ scholarly works), Crossref (150M+ records with DOIs) and English Wikipedia (~7M articles), all queried in real time. Optional general-web mode uses your own free Google Programmable Search key, stored only in your browser. Q: How is the similarity percentage calculated? A: We split your text into sentences, trigram-match each key sentence against source records, and divide the words in matched sentences by your total words. It is an honest arithmetic score — not a proprietary 'Turnitin-style' index, and we never claim otherwise. Q: Is my text uploaded or stored? A: Your text stays in your browser. Only short search-query versions of checked sentences are sent over HTTPS to the source APIs. Nothing is saved on our side; session results cache in your own browser only. Q: Why didn't it find a match that Turnitin finds? A: Turnitin matches paywalled journals and a private student-paper database. We check named open sources only and say so plainly — we will not fake a bigger corpus than we actually search. Q: How do I lower my similarity score honestly? A: Quote with citation marks, paraphrase properly, and add a reference for every source you used — then re-check here. Pair it with our paraphrasing tool and citation generator. Q: Does it work on mobile? A: Yes — it is a normal web page, works on iPhone and Android with nothing to install. ## Plagiarism Checker for PDF URL: https://toolfyra.com/plagiarism-checker-pdf.html Category: PDF Tools Check a PDF for plagiarism free: the PDF is read locally in your browser (pdf.js), its text is extracted and checked in real time against OpenAlex, Crossref and Wikipedia. Students are usually handed their brief in PDF form and asked to hand one back — so this checker speaks PDF. The file is opened with pdf.js entirely on your device: the text layer is extracted, and only short search queries from that text go out to the named open sources. Image-only scans have no text layer, and we detect and tell you that honestly instead of returning a fake 0%. Q: Is my PDF uploaded to a server? A: No. pdf.js opens and reads the file inside your browser; only short search queries derived from the extracted text are sent to the source APIs. Q: It says 'no text layer' — why? A: Your PDF is a scan (images of pages). Text extraction needs a digital text layer. Run an OCR tool first, then paste the text into the main checker. Q: Which sources are checked? A: The same honest set as the main tool: OpenAlex, Crossref and Wikipedia in real time, plus optional general-web mode with your own free Google key. Q: How large a PDF can I check? A: The engine checks the 12 longest key sentences per run — enough to profile a typical essay or report chapter. Very large theses: check chapter by chapter. Q: Is it free? A: Completely — no signup, no watermark, no per-day cap imposed by us (source APIs may apply their own fair-use limits). Q: Does it work on iPhone/Android? A: Yes — file picking and checking work in modern mobile browsers. ## Text Similarity Checker URL: https://toolfyra.com/text-similarity-checker.html Category: Text Tools Compare two texts side by side and get an honest overlap percentage with the longest common phrases highlighted. 100% local — nothing is uploaded. Free, instant. This is the tool teachers and editors actually need: paste two versions — a student submission and a reference answer, your draft and a source you must not copy, two candidate intros — and get a precise overlap score plus the longest common word sequences listed verbatim. It is the same shingle-matching arithmetic search engines use for duplicate detection, running entirely on your device. Nothing is uploaded, nothing is stored. Q: What counts as a good/bad similarity score? A: There is no universal threshold: identical boilerplate can be innocent, 10% copied argumentation can be fatal. Read the highlighted common phrases and judge the meaning, not just the number. Q: How is the percentage computed? A: Three-word trigram containment: shared trigrams divided by the smaller text's trigram count, plus a longest-common-sequence listing. Same family of arithmetic search engines use for near-duplicate detection. Q: Is either text uploaded? A: No — comparison runs 100% in your browser. Nothing leaves the page. Q: Can it compare translations? A: No — it compares word overlap, so translations will score low. It is for same-language comparison. Q: Teacher use-case: is it fair to students? A: It shows exactly which phrases overlap so you can have an evidence-based conversation instead of accusing on a raw number. Q: Is it free on mobile? A: Yes — instant, free, no app install. ## Paraphrasing Tool URL: https://toolfyra.com/paraphrasing-tool.html Category: Text Tools Free paraphrasing tool that does what it says: word-level synonym rewriting you control — click any word to cycle alternatives. Clearly labeled, no fake AI claims, nothing uploaded. Let's be honest about what a browser tool can do. This rewriter replaces words with genuine alternatives from a curated synonym dictionary — in front of your eyes, one click per word. It does not pretend to be a sentence-generating AI, and it will not 'humanize' anything. What it does do: break up repetition, help you reword a sentence you wrote yourself, and pair with citations when you paraphrase a source. Every green word is clickable — cycle alternatives until the sentence sounds like you. Your text never leaves the page. Q: Is this an AI paraphraser? A: No — and we won't pretend otherwise. It performs dictionary-based word-level rewriting with your control. No language model generates sentences here. Q: Will it beat Turnitin or similar checkers? A: No tool honestly promises that, and 'rewrite to hide plagiarism' is the wrong goal anyway. Use it to reword your own drafts, then cite your sources properly. Q: How do I use it ethically? A: Rewrite your own writing, or paraphrase a source and cite it. Spinning someone else's text to pass it off as yours is plagiarism on every campus. Q: Why do only some words change? A: The curated dictionary covers common words; toggle 'long words only' for conservative edits. Click any green word to cycle through its alternatives. Q: Is my text uploaded? A: No — everything happens in your browser. Nothing is sent or stored. Q: Is it free? A: Completely — no signup, no word cap, no watermark. ## Link Shortener (No Signup, No Expiry) URL: https://toolfyra.com/link-shortener.html Category: Link & Bio Tools Free link shortener with two honest modes: a private serverless portable link (destination encoded in the link, never expires) and an optional ultra-short mode via TinyURL. No signup, no click tracking of our own. Real shorteners like bit.ly work by storing your URL in a database and handing you a tiny slug. We offer both worlds, clearly labelled. Ultra-short mode asks TinyURL to store your destination and returns a classic ~26-character link (your URL then lives on TinyURL's registry — we proxy the request without storing anything). Private mode stores nothing anywhere: the destination is compressed (LZ) and encoded into the link itself, so it can never expire or be repurposed — but a link that carries its destination can only be shorter than the destination when the destination has repetition to compress; a 60-character random UUID is mathematically incompressible, and in that case we say so plainly instead of faking a statistic. Nothing is uploaded and nothing is stored: everything runs in your browser, and the page holds no server-side copy of what you type. Close the tab and it is gone. Q: Does the link expire? A: Ultra-short links live as long as TinyURL keeps them (years in practice). Private links never expire — the destination is inside the link itself. Q: Is my link tracked? A: We have no click logs and no tracking pixels in either mode. TinyURL may count clicks on its own service in ultra-short mode — that is the trade-off of a database-backed slug. Q: Why can private mode not shorten a UUID link? A: Information theory: a reversible link must carry the destination's entropy. Random IDs have no repetition to compress, so any serverless encoding is at best the same length. We show an honest note instead of a fake 'saved' number. Q: When does private mode actually shorten? A: Long URLs with repeated structure — UTM parameters, session tokens, repeated path segments — compress well and come out shorter than the original. Q: Can someone change where my private link points? A: No. The destination is part of the link, not a database record someone else controls. Q: Does private mode work offline? A: Yes — shortening and decoding happen entirely in your browser. ## Link-in-Bio Builder (Linktree Alternative) URL: https://toolfyra.com/link-in-bio-builder.html Category: Link & Bio Tools Build a Linktree-style bio page in minutes: add your links, pick a theme, preview live, then download the page as a single HTML file and host it anywhere free. No account, no monthly fee. Link-in-bio pages exist because Instagram, TikTok and X allow only one clickable link. The usual answer is a hosted service that charges for themes, adds its own branding, and can suspend your page. This builder produces the same kind of page as a single self-contained HTML file that you own: drop it on GitHub Pages, Netlify, Vercel or any static host for free, edit it whenever you like, and keep every visitor statistic to yourself. Nothing you type here is uploaded anywhere. Q: Is this really free forever? A: Yes — you get the HTML file. Hosting a static file on GitHub Pages or Netlify costs nothing. Q: Do I need an account? A: No. Nothing is saved, so there is nothing to sign up for. Q: Can I add unlimited links? A: Yes. The usual services cap features behind paid tiers; here the only limit is your page length. Q: Will my links be tracked? A: Only if you add your own analytics snippet — the generated page has no tracking of its own. Q: Where do I host the file? A: GitHub Pages, Netlify Drop, Vercel, Cloudflare Pages — all free for static files. Q: Does it work on phones? A: Yes — the generated page is responsive and fast on mobile. ## QR Code Generator for Links URL: https://toolfyra.com/link-qr-generator.html Category: Link & Bio Tools Turn any link into a high-quality QR code: choose size and error correction, download a crisp PNG. Generated in your browser — the URL is never sent anywhere. QR codes are how offline material sends people online: product packaging, restaurant menus, wedding invites, shop windows, resumes. This generator builds the code locally with the same library the rest of the site uses, so your URL never touches a server — important when the link contains a discount code, a personal portfolio or a payment page. Error correction lets the code keep working even when it is partly covered by a logo or printed on a curved surface. Q: Is my link sent to a server? A: No — the code is drawn in your browser and nothing leaves the page. Q: What error correction should I pick? A: L (7%) for clean prints, M (15%) normally, Q (25%) if you overlay a logo, H (30%) for curved or dirty surfaces. Q: Can I print it large? A: Yes — choose a bigger module size so the PNG stays sharp at poster scale. Q: Do QR codes expire? A: A static QR code never expires; it simply encodes the URL. Only the destination can change. Q: Will phones open it? A: Yes — both iOS Camera and Android Google Lens read plain URL codes without an app. Q: Can I test it before printing? A: Always scan it with your own phone first, and check the landing page on mobile data. ## Virtual Dress Try-On URL: https://toolfyra.com/virtual-dress-try-on.html Category: Style & Shopping Try dresses online free: upload your photo, overlay any dress image, then adjust size, position, opacity and rotation to see how it sits on you before you order. Nothing is uploaded. Online dress shopping fails in one predictable way: the model's body, the studio lighting and the pinning at the back are all working against you, so what arrives rarely matches the picture. A virtual try-on removes some of that guesswork. Load a photo of yourself in fitted clothes, then overlay the product image from the store and match it to your shoulders and waistline. You will not get a perfect fit simulation — that needs body scanning — but you will see proportion, length and colour against your own skin tone, which is where most returns actually come from. Q: Is my photo uploaded? A: No. Nothing you load here is uploaded. The photo and the product image are read into this tab's memory only, drawn on a canvas, and discarded when you close the tab or press Clear. There is no server-side copy, no account and no history. Q: How accurate is this? A: It shows proportion, length and colour on your body. It cannot simulate fabric drape or true fit — for that, always check the size chart's bust, waist and hip numbers. Q: What photo works best? A: Full-length, facing the camera, in fitted clothes, with even lighting and a plain background. Q: Which dress image should I use? A: The product shot on a plain background, ideally a PNG. Save it from the store page first. Q: Can I compare two dresses? A: Yes — save a preview of each and open them side by side. Q: Does it work on phones? A: Yes. Use the Size slider instead of pinch, and drag with one finger to position. ## Virtual Shoes Try-On URL: https://toolfyra.com/virtual-shoes-try-on.html Category: Style & Shopping See shoes on your own feet before buying: upload a photo of your feet, overlay the shoe image, match the angle and scale, and save a preview. Runs entirely in your browser. Shoe photos are shot at a flattering three-quarter angle on a size-8 foot, which tells you almost nothing about how the pair will look on you. Loading a photo of your own feet and overlaying the product shot fixes the two things that cause most returns: apparent size and colour. Warm-white studio lighting makes ivory look white and tan look brown, so comparing the product against your real skin under your real lighting catches that. As with any overlay preview, it is a guide to proportion and colour — not a substitute for the brand's size chart in centimetres. Q: Is my photo uploaded? A: No. Nothing you load here is uploaded. The photo and the product image are read into this tab's memory only, drawn on a canvas, and discarded when you close the tab or press Clear. There is no server-side copy, no account and no history. Q: What camera angle should I use? A: Match the product photo — usually standing, camera at floor height, both feet visible. Q: How do I get the scale right? A: Measure your foot in cm, then scale the overlay until the shoe length matches your foot's length in the photo. Q: Will it show width fit? A: No. Width and arch fit need a real fitting or the brand's width codes (B, D, 2E). Q: Can I try heels and sneakers both? A: Yes — load one product image at a time and save a preview of each. Q: Does it work offline? A: Yes, once the page is loaded. ## Virtual Handbag Try-On URL: https://toolfyra.com/virtual-handbag-try-on.html Category: Style & Shopping Check a handbag's real proportions on you: upload a photo, overlay the bag, scale it to the listed dimensions and see whether it is a daily tote or a mini. All in-browser, nothing uploaded. Handbag listings almost never show the bag next to a person, so a 'medium tote' can arrive anywhere from a lunchbox to a gym bag. The fix is arithmetic plus an overlay: listings do state the dimensions, so scale the product image until its height matches those numbers relative to your own torso in the photo. You immediately see strap drop against your shoulder, whether the bag hits your hip or your waist, and whether the colour competes with the outfits you actually wear. Q: Is my photo uploaded? A: No. Nothing you load here is uploaded. The photo and the product image are read into this tab's memory only, drawn on a canvas, and discarded when you close the tab or press Clear. There is no server-side copy, no account and no history. Q: How do I scale it correctly? A: Take the bag's listed height in cm and compare it with your torso: an average waist-to-shoulder distance is roughly 40–45 cm, so a 25 cm bag should cover about 60% of that. Q: What about strap length? A: Check the listed strap drop. Under 20 cm sits at the armpit, 25–30 cm sits at the hip, over 55 cm is crossbody. Q: Can it show leather texture? A: No — an overlay cannot simulate material. Zoom into the product photos for grain and hardware. Q: Which photo of me works best? A: Standing, arms relaxed, plain background, camera at chest height. Q: Does it work on phones? A: Yes — use the Size slider rather than pinch. ## Lipstick Shade Finder URL: https://toolfyra.com/lipstick-shade-finder.html Category: Style & Shopping Find your best lipstick shades: pick your skin depth and undertone (warm, cool or neutral), get a ranked list of shade families with the reasoning, plus shades to avoid and a swatch preview. Shade advice online is mostly brand marketing, which is why the same 'universal red' recommendation appears on a dozen sites. Colour analysis is more mechanical than that: what flatters you depends on skin depth and, more importantly, undertone. Warm undertones (yellow, golden, peachy) carry orange-based and brick shades; cool undertones (pink, red, bluish) carry blue-based berries and true reds; neutral sits between and can borrow from both. This tool applies those rules and shows you a swatch strip, so you can hold your wrist next to the screen in daylight and see the difference rather than trusting a name like 'rosewood'. Q: How do I find my undertone? A: In daylight: greenish veins suggest warm, bluish-purple suggest cool, a mix suggests neutral. Silver jewellery usually flatters cool, gold flatters warm. Q: Is this the same for every brand? A: The shade family is. Names differ wildly between brands, so match by description (blue-based red, brick, mauve) not by name. Q: Can I trust the swatch colours on screen? A: Approximately. Screens differ, so always check in daylight and, where possible, order a sample or swatch in store. Q: What if I'm between two depths? A: Go one step deeper for evening looks and one step lighter for daytime. Q: Does it account for my natural lip colour? A: Partly — deeper natural lip pigment shifts every shade warmer and darker, so test on the lip, not the hand. Q: Is my data saved? A: No. Nothing is stored or uploaded; reload and it is blank. ## 3D Product Viewer (GLB/GLTF) URL: https://toolfyra.com/3d-product-viewer.html Category: Style & Shopping Inspect 3D product models in your browser: load a .glb or .gltf file, orbit, zoom and measure proportions before you buy or before you print. Model stays on your device. A product photo shows one angle chosen by the seller. A 3D model shows every angle, including the back, the underside and the joinery. This viewer runs the open standard glTF entirely in your browser, so the model file is never uploaded — which matters when the file is a supplier's unreleased packaging design or a paid asset. Use it to check real proportions before ordering furniture, to inspect a 3D-print file for thin walls before you spend filament, or to review a packaging mock-up without installing specialist software. Q: Is my model uploaded? A: No. The file is parsed in your browser and never sent anywhere. Q: Which formats work? A: glTF 2.0 — .glb (binary, single file) and .gltf with its .bin and textures in the same folder. Q: Where do I get product models? A: Furniture brands increasingly ship .glb on the product page; SketchUp and Blender export glTF; CGTrader and Sketchfab list free glTF samples. Q: Can I measure the model? A: The viewer reports the model's bounding-box size if the file carries real-world units; many exports are unitless, so always confirm with the seller. Q: Does it work on phones? A: Yes — drag to orbit, pinch to zoom. Q: Why is my model invisible? A: Usually a missing texture folder (.gltf needs its .bin and images alongside) or a model with no lights — try the built-in demo to confirm the viewer works. ## Wallpaper & Paint Room Preview URL: https://toolfyra.com/wallpaper-room-preview.html Category: Home & Decor Preview wallpaper and paint colours in your own room photo before buying: upload a wall photo, overlay the pattern or colour, adjust scale, opacity and blend, and save the result. Wallpaper samples are 10 cm squares, which is exactly the wrong scale for judging a pattern: a large floral looks delicate on a swatch and overwhelming on a wall. Painting is the same story in reverse — a colour that looks soft on a chip can go intense across four metres, especially under warm evening bulbs. This preview puts the pattern or colour onto your own wall at an adjustable scale so you can judge repeat size, how much the pattern fights with your furniture, and how the colour behaves against your floor and curtains. Q: Is my room photo uploaded? A: No. The photo and the pattern are read into this tab's memory only, drawn on a canvas, and discarded when you close the tab. There is no server copy. Q: How do I get the pattern scale right? A: Wallpaper listings state the pattern repeat in cm. Scale the overlay until one full repeat covers the same fraction of your wall as it would in real life. Q: Can I preview paint instead of wallpaper? A: Yes — switch to the colour mode and pick any shade; use the opacity slider to judge depth. Q: Why does the colour look different on screen? A: Screens are backlit and rooms are not. Always confirm with a physical sample on the actual wall, viewed at morning, noon and evening light. Q: Can I preview a feature wall only? A: Yes — the overlay is draggable, so you can position it on one wall. Q: Does it work on phones? A: Yes. Use the sliders for scale and drag with one finger to position. ## Outfit Colour Combiner URL: https://toolfyra.com/outfit-color-combiner.html Category: Style & Shopping Build outfits that actually match: pick your base piece, get scientifically harmonised colour combinations (complementary, analogous, triadic, neutral) with hex codes and the reasoning for each pairing. Most 'what goes with what' advice is a list of opinions. Colour combinations are not arbitrary — they follow relationships on the colour wheel, which is why a navy blazer and a rust chinos look deliberate while navy and a slightly-off black look accidental. This tool takes the colour of the piece you already own and generates four families of pairings: complementary (high contrast, bold), analogous (neighbouring hues, easy and calm), triadic (balanced and lively) and neutrals (the safe backbone of a wardrobe). Each comes with hex codes, so you can match a garment in an online store instead of guessing from a name like 'oatmeal'. Q: Why do some colours clash? A: Usually because they are near-neighbours with different undertones — e.g. a warm brown next to a cool black. Exact hues from the wheel avoid that. Q: Can I use the hex codes when shopping? A: Yes. Compare them against the product photo, but remember screens and fabric dye differ — treat hex as a target, not a guarantee. Q: What if my wardrobe is all black and white? A: Use the neutral family. Black pairs with every saturated colour; white softens high-contrast pairings. Q: Does skin tone matter? A: For colours near your face, yes — see the Lipstick Shade Finder for undertone rules. For trousers, shoes and bags, the colour wheel matters more. Q: How many colours should an outfit have? A: Three is the practical ceiling: one dominant, one supporting, one accent. Q: Is anything saved? A: No — the tool is stateless and nothing is uploaded. ## Gift Idea Finder URL: https://toolfyra.com/gift-idea-finder.html Category: Gifts & Occasions Find a gift that actually lands: pick the person, the occasion, your budget and their interests, and get ranked ideas with the reasoning, an estimated cost and a backup option for each. Gift advice usually amounts to a list of product categories, which is why everyone ends up with the same candle. A useful suggestion depends on three things that category lists ignore: who the person is to you, what they already spend their own money on, and what the occasion actually expects. This tool works from those inputs and returns ideas with the reasoning attached, plus a rough cost band so you can stay inside budget. Nothing here is sponsored and nothing is stored — pick again as many times as you like. Q: Are these sponsored or affiliate links? A: No. There are no affiliate links and no products for sale — the ideas are generic on purpose so you can source them anywhere. Q: Are the prices accurate? A: They are indicative bands, not quotes. Prices vary a lot by country and season. Q: What if none of the ideas fit? A: Change the interest tags — the ranking is driven mostly by those. Q: Does it work for groups or office gifts? A: Yes — pick 'Colleague' or 'Friend' and a lower budget band for Secret Santa style gifting. Q: Is my input saved? A: No. The tool is stateless; nothing is uploaded or stored. Q: What is the safest gift when I barely know the person? A: Consumables beat objects: good coffee, a bakery box, or a plant. They do not create clutter and they do not need to match taste. ## Crop PDF Online URL: https://toolfyra.com/pdf-cropper.html Category: PDF Tools Crop PDF pages free: set margins or pick a crop area per page, preview the result, and download the trimmed PDF. Runs in your browser — the file is never uploaded. Scanned documents and exported slides usually carry a band of white margin that wastes screen space and prints badly. Cropping fixes that, and it is also how you cut a two-up page into two single pages. This cropper works entirely in your browser with pdf-lib: it rewrites each page's crop box, so the original content is untouched and nothing is re-encoded. Because there is no server, a 200-page confidential document is just as safe here as it is offline. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Is my PDF uploaded? A: No. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Does cropping delete content? A: No. It changes the visible crop box; the underlying content stays in the file, so you can re-crop later. Q: Can I use different margins per side? A: Yes — top, right, bottom and left are separate fields. Q: Will it fix a skewed scan? A: It removes the margins but does not deskew. Rotate first if the scan is tilted. Q: Any page limit? A: No account limits. Very large files are only bounded by your device's memory. Q: Does it keep links and text selectable? A: Yes — the text layer is preserved. ## Organize PDF Pages (Reorder, Rotate, Delete) URL: https://toolfyra.com/pdf-organizer.html Category: PDF Tools Reorder, rotate and delete PDF pages free: see every page as a thumbnail strip, drag the order, rotate any page, drop the ones you do not need, then download. Nothing is uploaded. PDF exports rarely come out in the order you need: a scanner puts page 2 first, a slide deck carries three blank dividers, and one page is upside down. Rebuilding the file in another program usually means re-exporting the whole document. This organizer edits the page tree directly in your browser, so reordering is instant and lossless — the pages themselves are not re-rendered, which is why image quality and text selectability survive. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Is my PDF uploaded? A: No. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Does reordering reduce quality? A: No. Pages are moved in the page tree, not re-rendered. Q: Can I rotate a single page? A: Yes — each thumbnail has its own rotate button. Q: What if I delete the wrong page? A: Reload the original file; the source is never modified in place. Q: Any page limit? A: No account limits; large files are bounded by device memory. Q: Can I extract pages instead? A: Yes — delete everything else, or use the dedicated page extractor tool. ## Unlock PDF (Remove Password) URL: https://toolfyra.com/pdf-unlock.html Category: PDF Tools Remove the password from a PDF you own: enter the password once, get an unrestricted copy you can edit, print and share. Decryption happens in your browser — the file is never uploaded. Password-protected PDFs are annoying when you are the owner: the browser asks again on every device, some editors refuse to open them at all, and merging them into another document fails silently. This tool decrypts your copy locally and writes a new, unrestricted file. It only works when you know the password — it is not a password breaker, and it will not open somebody else's protected document. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Is my PDF or password uploaded? A: No. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. The password is used in memory only and never stored. Q: Can it break a password I don't know? A: No. This is a decryptor for files you own, not a cracker. Q: Does it remove permissions too? A: Yes — printing, copying and editing restrictions are lifted in the new copy. Q: Will quality change? A: No. The page content is copied as-is. Q: What if the PDF is encrypted with an owner-only password? A: Those open without a password; load the file and download to get an unrestricted copy. Q: Any file-size limit? A: No account limits; bounded only by device memory. ## Password Protect PDF URL: https://toolfyra.com/pdf-password-protect.html Category: PDF Tools Add a password to any PDF free: encryption runs in your browser with pdf-lib, so the document and the password never touch a server. Download the protected file instantly. Sending a bank statement, a contract or a client report by email means the file sits in at least three mail servers unprotected. Adding a password costs nothing and takes ten seconds. Most online protectors upload your document to do it, which is the opposite of the point. This one encrypts locally: the password is applied to the copy in your browser's memory and the protected file is written straight to your device. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Is my PDF uploaded? A: No. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Do you store the password? A: No. It is used in memory for the encryption and discarded when the tab closes. Q: What if I forget the password? A: The file cannot be opened. There is no recovery, because we never had a copy. Q: How strong should the password be? A: Twelve characters or more, mixed case with a number — the encryption is only as strong as the password. Q: Can the recipient still print it? A: Yes, once they enter the password. Q: Does it work on phones? A: Yes — the page is responsive and the encryption runs locally. ## Flatten PDF (Merge Form Fields) URL: https://toolfyra.com/pdf-flatten.html Category: PDF Tools Flatten a fillable PDF free: form fields and annotations become fixed page content, so nobody can change the answers. Runs in your browser — the file is never uploaded. A filled form is still editable: anyone who opens it can click a field and retype the answer, which matters when the document is an invoice, a consent form or an application. Flattening merges the field values into the page content, so the document behaves like a printout. This is also the fix when a form will not submit through a government or bank portal that rejects interactive fields. Everything happens locally. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Is my form uploaded? A: No. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Will the answers stay visible? A: Yes — the current field values are baked into the page. Q: Can I un-flatten it later? A: No. That is the point: the fields stop being editable. Q: Does it keep the text selectable? A: Flattened text may become part of the page content; keep the original if you need to copy text later. Q: Why would a portal reject an interactive PDF? A: Some validators require a flat document so the submitted content cannot change after upload. Q: Any page limit? A: No account limits. ## HTML to PDF Converter URL: https://toolfyra.com/html-to-pdf.html Category: PDF Tools Convert HTML to PDF free: paste HTML or load an .html file, style it, then export a print-ready PDF. Rendering happens in your browser — no upload, no watermark. Invoices, certificates, resumes and reports are often written as HTML because that is what a system can produce — but the recipient wants a PDF that looks identical on every device. Online converters solve this by uploading your markup to a headless browser, which is a strange thing to do with a document that may contain personal data. This converter renders the HTML in your own browser and hands it to the print engine, so the output matches what you see on screen, down to the web fonts. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Is my HTML uploaded? A: No. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Will CSS and fonts work? A: Yes — your own CSS is applied, and system fonts render exactly as previewed. Q: Can I load an .html file? A: Yes — use the file input; the markup is read locally. Q: Are external images included? A: Only if your browser can fetch them; images on a blocked or private host will not load. Q: Why use the print engine instead of a library? A: It is the only renderer guaranteed to match what you see on screen, including pagination. Q: Any page limit? A: No account limits. ## PDF to Excel Converter (Tables to CSV) URL: https://toolfyra.com/pdf-to-excel.html Category: PDF Tools Extract tables from a PDF into a spreadsheet free: the text layer is parsed in your browser, rows are detected by position, and you download a CSV that opens straight in Excel. No upload. A PDF stores text as positioned glyphs, not as a table, which is why copy-pasting a price list produces one long line. This converter reads the text layer with pdf.js, groups fragments by their vertical position into rows, splits columns on the horizontal gaps, and writes a CSV. It works best on digitally produced PDFs — invoices, statements, reports. Scanned images need OCR first, and the tool tells you honestly when it finds no text layer instead of handing you an empty sheet. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Is my PDF uploaded? A: No. Your file never leaves this page — pdf-lib runs in your browser, there is no upload endpoint on this site, and the document is dropped from memory when you close the tab. Q: Does it produce a real .xlsx? A: It produces CSV, which Excel, Google Sheets and LibreOffice all open natively — and it keeps the data plain and portable. Q: What about scanned PDFs? A: They have no text layer, so run OCR first. The tool reports honestly when no text is found. Q: How accurate is column detection? A: Columns are split on horizontal gaps, so evenly spaced tables work well; overlapping columns may need a manual nudge. Q: Can I choose the page? A: Yes — enter the page number before extracting. Q: Any page limit? A: No account limits. ## Lucky Number Calculator URL: https://toolfyra.com/lucky-number-calculator.html Category: Calculators Calculate your lucky number free from your date of birth using the standard numerology method (digit reduction), plus your expression and birthday numbers. Nothing is saved or uploaded. The most widely used method reduces the full birth date to a single digit, keeping the master numbers 11, 22 and 33 unreduced. This tool shows every step of that reduction rather than just the answer, so you can see how 14/07/1993 becomes 7. It also gives the birthday number (the day on its own) and a set of secondary numbers derived the same way, which is what most numerology sources mean when they talk about 'your numbers'. This tool follows a traditional belief system, not a scientific model. Use it for fun and self-reflection — it makes no prediction about your future. Q: Is my birth date saved? A: No. The calculation runs in your browser and nothing is stored or sent anywhere. Q: Which method does it use? A: The standard Pythagorean reduction of the full date, keeping 11, 22 and 33 as master numbers. Q: Why is 11 not reduced to 2? A: Numerology treats 11, 22 and 33 as master numbers and leaves them unreduced. Q: Is this scientific? A: No — it is a belief system. This tool follows a traditional belief system, not a scientific model. Use it for fun and self-reflection — it makes no prediction about your future. Q: Can I use a different date format? A: The date picker handles it; the calculation uses day, month and year separately. Q: What is the birthday number? A: Just the day of the month, reduced to one digit — a secondary number many sources list. ## Zodiac Sign Finder (Star Sign) URL: https://toolfyra.com/zodiac-sign-finder.html Category: Calculators Find your star sign from your date of birth: exact date ranges, element, ruling planet, symbol and traditional compatibility. Free, instant, nothing saved. The twelve sun signs are defined by fixed date ranges, and the boundaries are where most confusion happens: someone born on 22 December is a Capricorn while 21 December is a Sagittarius. This tool uses the standard tropical ranges and shows the range it matched, so you can see exactly which side of a cusp you fall on. It also lists element, modality and ruling planet, which are the three attributes astrology actually uses to compare signs. This tool follows a traditional belief system, not a scientific model. Use it for fun and self-reflection — it makes no prediction about your future. Q: Is my birth date stored? A: No. Everything runs in your browser; nothing is saved or uploaded. Q: What if I was born on a cusp? A: The tool shows the exact range it matched, so you can see which sign the date falls into. Cusp dates are decided by the year's exact Sun position in professional charts. Q: Which date ranges do you use? A: The standard tropical ranges used by most Western astrology sources. Q: Is this scientific? A: No. This tool follows a traditional belief system, not a scientific model. Use it for fun and self-reflection — it makes no prediction about your future. Q: Does it need my birth time? A: No — a sun sign needs only the date. A full birth chart needs time and place. Q: What are element and modality? A: Element is fire/earth/air/water; modality is cardinal/fixed/mutable. Astrology compares signs using both. ## Biorhythm Calculator URL: https://toolfyra.com/biorhythm-calculator.html Category: Calculators Calculate your biorhythm cycles free: the 23-day physical, 28-day emotional and 33-day intellectual curves from your birth date, with a 30-day chart. All in your browser. Biorhythm theory proposes three fixed cycles that run from the moment of birth: a 23-day physical cycle, a 28-day emotional cycle and a 33-day intellectual cycle. Each is a sine wave, so any given day sits somewhere between the peak and the trough, and the days where a curve crosses zero are traditionally called critical days. This tool computes the exact phase for today and draws the next 30 days so you can see the pattern rather than just a number. The theory dates from the early 1900s and is not supported by scientific evidence — it is presented here as the classic calculation, done properly. Q: Is my birth date stored? A: No — the calculation is local and nothing is saved. Q: What do the percentages mean? A: The position on each sine curve: +100% is the peak, 0% is the critical crossing, −100% is the trough. Q: What is a critical day? A: The day a cycle crosses zero, traditionally considered a transition point. Q: Is biorhythm scientific? A: No. It is an early twentieth-century idea without scientific support — treat the chart as a curiosity. Q: Why 23, 28 and 33 days? A: Those are the cycle lengths the original theory specified. Q: Can I check a past date? A: Yes — change the target date field to any date. ## Lucky Color Finder (By Birth Date) URL: https://toolfyra.com/lucky-color-finder.html Category: Calculators Find your lucky colour free from your birth date and day of the week, using the traditional numerology colour map, with hex codes you can actually use in design or clothing. Two traditional systems map dates to colours. Numerology assigns a colour to each Life Path digit — 1 to red, 2 to green, 3 to yellow and so on — while the weekday system assigns a colour to each day of the week, which is where 'wearing yellow on Thursday' comes from. This tool computes both and, because a colour name is useless when you are actually shopping or designing, it also gives the hex code so you can match the shade precisely. This tool follows a traditional belief system, not a scientific model. Use it for fun and self-reflection — it makes no prediction about your future. Q: Is my birth date saved? A: No — local calculation, nothing stored or uploaded. Q: Which system does it use? A: Both the numerology colour map (by Life Path number) and the traditional weekday colour map. Q: Why hex codes? A: So you can match the exact shade when buying clothes or setting a design colour. Q: Is this scientific? A: No. This tool follows a traditional belief system, not a scientific model. Use it for fun and self-reflection — it makes no prediction about your future. Q: What if the two colours clash? A: Most people pick one — numerology colour for long-term use, weekday colour for that day. Q: Can I use it for a logo? A: The hex codes are ordinary sRGB values, so yes — but check contrast for readability. ## Pet Age Converter (Dog & Cat Years) URL: https://toolfyra.com/pet-age-converter.html Category: Calculators Convert dog and cat age to human years free using the size-aware formula, not the old ×7 myth. Enter the pet's age and weight, get the equivalent human age and life stage. The ×7 rule came from a rough average and falls apart at both ends: a one-year-old dog is not a seven-year-old child, it is closer to a teenager, and large breeds age faster than small ones after the first two years. The commonly cited veterinary approximation gives the first year about fifteen human years, the second about nine more, then roughly four to six per year depending on size. This tool applies that curve by weight band and reports the life stage — puppy, adult, senior, geriatric — which is what actually changes how you feed and exercise the animal. It is an estimate, not a diagnosis. Q: Is anything stored? A: No — it is a local calculation. Q: Why is ×7 wrong? A: Dogs mature very fast in year one and then slow down; a single multiplier cannot fit that curve. Q: Does size matter? A: Yes for dogs — large and giant breeds age faster after year two. Cats use one curve. Q: How accurate is this? A: It is a widely used approximation. Breed, genetics and health matter more than any formula. Q: What is a life stage? A: Puppy/kitten, adult, senior, geriatric — vets change diet and screening by stage. Q: Should I change food at senior? A: Usually yes, but confirm with your vet; it depends on the individual animal. ## Pet Food Calculator (Daily Portions) URL: https://toolfyra.com/pet-food-calculator.html Category: Calculators Work out your pet's daily food amount free: resting and maintenance energy needs from weight, age and body condition, converted into grams or cups. A guide to check with your vet. Feeding guides on the bag are averages written for an animal that may look nothing like yours. The standard approach is to start from resting energy requirement — roughly 70 × (body weight in kg)^0.75 — then multiply by a factor for life stage, neuter status and activity. That gives a daily calorie target, which you divide by the calorie density on your food's label to get grams. This tool does that calculation and lets you enter your own food's kcal per cup or per 100 g. It is a starting point: body condition score and your vet's advice beat any formula. Q: Is anything stored? A: No — local calculation only. Q: Where does the formula come from? A: RER ≈ 70 × kg^0.75, multiplied by a life-stage/activity factor — the standard veterinary starting point. Q: What if my pet is overweight? A: Choose the overweight condition; the tool reduces the target. Weight loss should still be supervised by a vet. Q: Wet or dry food? A: Enter the kcal density printed on that food — dry is often 350–400 kcal/100 g, wet 80–110 kcal/100 g. Q: How often should I weigh my pet? A: Monthly during any weight change, then every few months once stable. Q: Is this a diagnosis? A: No. It is a starting portion to adjust based on body condition and vet advice. ## Pet Name Generator URL: https://toolfyra.com/pet-name-generator.html Category: Generators Generate pet names free: filter by animal, style and starting letter, get meanings and origins, and copy any name in one click. No signup, nothing saved. Choosing a pet name feels trivial until you have to say it forty times a day at a dog park. The practical rules trainers repeat are short: one or two syllables, a hard consonant at the start, and nothing that rhymes with a command — 'Bo' and 'no' are a bad pair. This generator keeps those constraints in mind while letting you filter by animal, style and starting letter, and it shows the origin so you know what you are calling the animal. One click copies the name; nothing is stored. Q: Is anything saved? A: No — the generator runs locally and nothing is stored. Q: How many syllables should a pet name have? A: One or two. Long names get shortened anyway, and short names carry better outdoors. Q: Any sounds to avoid? A: Names that rhyme with commands — Bo/no, Jay/stay, Kit/sit. Q: Can I filter by letter? A: Yes — pick a starting letter to match another pet's name. Q: Do you show meanings? A: Where the name has a known origin, yes. Q: Can I use it for a rabbit or bird? A: Yes — the animal filter covers dog, cat, bird, rabbit and fish. ## Child Height Predictor URL: https://toolfyra.com/child-height-predictor.html Category: Health & Fitness Estimate your child's adult height free using the standard mid-parental height method plus the doubling rule, with the usual ±8 cm range. A guide, not a medical prediction. Two simple methods are used in practice. The mid-parental method averages the parents' heights, adds about 13 cm for a boy or subtracts about 13 cm for a girl, then divides by two; most children land within roughly 8 cm either side of that figure. The doubling method says a boy's height at two years and a girl's at eighteen months roughly doubles by adulthood. Both are population averages — nutrition, sleep, health and timing of puberty move the real number, and a paediatrician tracking the growth curve over time will always beat a single estimate. Q: Is anything stored? A: No — the calculation runs in your browser. Q: How accurate is it? A: Within about ±8 cm for most children. It is a population average, not a prediction for one child. Q: Why 13 cm? A: That is the average adult height difference between men and women used in the mid-parental formula. Q: What affects the real number most? A: Nutrition, sleep, overall health and when puberty starts. Q: Should I worry if my child is off the estimate? A: Talk to a paediatrician — what matters is the growth curve over time, not one measurement. Q: Does it work for toddlers? A: The doubling method is designed for exactly that age range. ## Screen Time Planner for Kids URL: https://toolfyra.com/screen-time-planner.html Category: Health & Fitness Plan healthy screen time free: age-based guideline ranges, a weekly schedule you can build and print, and a family agreement you can copy. Based on published paediatric guidance. Most paediatric guidance converges on the same shape: keep screens out of the first eighteen months apart from video calls, keep two-to-five-year-olds to roughly an hour a day of quality content with an adult present, and for older children replace a single number with a plan that protects sleep, homework, physical activity and offline social time first. That last part is what usually fails, because a rule with no schedule is not a plan. This tool gives you the age range and then lets you build the week around it, block by block, and print the result. Q: Is anything uploaded? A: No. The plan stays in this tab; save it with the print button or copy it. Q: Whose guidelines are these? A: The ranges published by major paediatric bodies, summarised. Always check the latest guidance for your country. Q: What about homework and video calls? A: Most guidance treats those separately from recreational screen time. Q: Can I save the plan? A: Use print → save as PDF, or copy the text. Nothing is stored on a server. Q: Does it work for teens? A: Yes — the teen band focuses on protecting sleep and activity rather than a fixed hour count. Q: Why does sleep matter most? A: Screens before bed delay sleep onset, and sleep drives growth, mood and attention in children. ## Chore Chart Generator for Kids URL: https://toolfyra.com/chore-chart-generator.html Category: Generators Build a printable weekly chore chart free: pick ages, assign tasks with points and rewards, then print or copy the chart. Age-appropriate task lists included. The reason chore charts fail is usually mismatch: a four-year-old cannot empty a dishwasher and a twelve-year-old will not do it for a sticker. This generator starts from age-appropriate task lists — the sort paediatric and parenting sources consistently recommend — then lets you assign days, set a point value and attach a reward, so the chart reflects what the child can actually do. The output is a plain printable grid, because a chart on the fridge works better than an app nobody opens. Q: Is anything saved? A: No — build it, print it, close the tab. Q: What can a 4-year-old actually do? A: Put toys in a box, put clothes in the hamper, wipe a table, water a plant, feed a pet with help. Q: What about a teenager? A: Laundry, cooking a simple meal, vacuuming, bins, dishes, walking the dog. Q: Should I pay for chores? A: That is a family decision. Many parents separate basic contribution from paid extras. Q: Can I print it? A: Yes — the print button opens the browser's print dialog; choose 'Save as PDF' to keep a copy. Q: How many chores is realistic? A: Two or three per day. More than that and the chart stops getting finished. ## Baby Name Generator URL: https://toolfyra.com/baby-name-generator.html Category: Generators Generate baby names free: filter by gender, origin and starting letter, see the meaning of every name, and copy your favourites in one click. No signup, nothing stored. Name lists online are usually ranked by popularity, which tells you what everyone else is choosing rather than what fits your family. This generator filters the other way — by origin and starting letter — so you can match a grandparent's name, keep siblings' initials distinct, or stay inside one language. Every result carries its origin and meaning, because a name you cannot explain is a name you may regret. Nothing is stored; the list regenerates each time. Q: Is anything saved? A: No — it runs locally and stores nothing. Q: Do the meanings come from anywhere reliable? A: They are the commonly cited etymologies for each name; spelling variants exist across languages. Q: Can I match siblings' initials? A: Yes — filter by starting letter. Q: Are neutral names included? A: Yes — choose 'Neutral / unisex'. Q: How do I shortlist? A: Copy the ones you like into a note; nothing is saved here on purpose. Q: Any names to avoid? A: Practical check: say it with your surname out loud, and check the initials. ## Daily Routine Builder URL: https://toolfyra.com/daily-routine-builder.html Category: Generators Build a daily routine free: add time blocks, drag to reorder, see the total scheduled hours and any overlaps, then print or copy the schedule. Nothing is stored on a server. Most routine advice tells you to wake at five and journal; what actually helps is seeing your real day laid out, because that is where the double-bookings and the two-hour gaps become obvious. This builder takes blocks with start and end times, sorts them, and warns you when two of them collide or when you have scheduled more than the hours available. It also marks the sleep window, since sleep is the one block that decides whether the rest holds. Print it, or copy it into a note. Q: Is my routine stored? A: No. It lives in this tab; use print or copy to keep it. Q: Does it detect overlaps? A: Yes — overlapping blocks are listed with a warning. Q: Can I reorder blocks? A: Yes — use the up/down buttons on each row. Q: What about sleep? A: Add it as a block; the tool counts it and shows how much is left in the day. Q: Can I print it? A: Yes — the print button opens the browser's print dialog. Q: Why flag overlaps? A: Because a plan with two things at 18:00 is not a plan, it is a wish. ## Habit Streak Tracker URL: https://toolfyra.com/habit-streak-tracker.html Category: Health & Fitness Track daily habits free: build streaks, see a 12-week heat map and your longest run. Data is stored only in your own browser — no account, no server, no tracking. Habit apps usually want an account, an email and permission to notify you — which is a lot of trust for a checkbox. This tracker keeps everything in your own browser's local storage: the streaks, the twelve-week heat map and the longest run all live on your device and nowhere else. Clearing your browser data clears it, which is the honest trade-off for not having an account. It suits one person on one device; for syncing across devices you would need an app with a login, and that is a different privacy bargain. Q: Where is my data stored? A: Only in your browser's local storage on this device. No account, no server, no analytics. Q: What if I clear my browser data? A: The streaks are lost — that is the trade-off for having no account. Q: Does it sync across devices? A: No. Syncing would require a server and an account. Q: How is a streak counted? A: Consecutive days ticked. A missed day resets that habit's streak, but the longest run is kept. Q: Can I delete a habit? A: Yes — the ✕ button removes it and its history. Q: How far back does the heat map go? A: Twelve weeks. ## Hobby Finder Quiz URL: https://toolfyra.com/hobby-finder.html Category: Generators Find a hobby that actually fits: answer six questions about your time, budget, energy and whether you want to be social, and get matched hobbies with real cost and time estimates. Hobby lists rank by popularity, which is useless if you have ninety minutes a week and no budget. This finder works from constraints instead: how much time you actually have, what you can spend to start, whether you want to be around people or alone, and whether you want to make something or move your body. It then scores each hobby against those answers and shows the starting cost and the weekly time it really takes, so the suggestion survives contact with your calendar. Q: Is anything stored? A: No — the quiz runs locally and stores nothing. Q: How is the fit score worked out? A: Each hobby carries time, cost, social and output tags; the score is how many of your answers it matches. Q: Are the costs realistic? A: They are typical starting costs, not quotes — second-hand gear usually cuts them substantially. Q: What if I have almost no time? A: Choose under two hours a week; the results will favour low-setup hobbies. Q: Can I redo the quiz? A: Yes — change any answer and the ranking updates immediately. Q: Do you suggest social hobbies? A: Yes, if you say you want company; otherwise it favours solo ones. ## Colour Contrast Checker (WCAG) URL: https://toolfyra.com/color-contrast-checker.html Category: Image Tools Check colour contrast free: enter foreground and background colours, get the exact WCAG contrast ratio and pass/fail for AA and AAA at normal and large text size. About one in twelve men has some colour vision deficiency, and low-contrast text fails far more people than that — outdoors on a phone, low contrast makes text unreadable for almost everyone. WCAG 2.1 sets the thresholds: 4.5:1 for normal text at AA, 3:1 for large text, and 7:1 for AAA. This checker computes the real relative-luminance ratio rather than a rough guess, tells you pass or fail at each level, and suggests how far you need to move the foreground colour to pass. Useful for designers, and it is the fastest way to check a slide or a poster before you print it. Q: Is anything uploaded? A: No — the calculation runs in your browser. Q: What ratio do I need? A: 4.5:1 for normal text at AA, 3:1 for large text (18pt or 14pt bold), 7:1 for AAA. Q: Why is my yellow-on-white failing? A: Yellow has high luminance, so it is close to white — the ratio ends up near 1.5:1. Q: Does it check non-text elements? A: The 3:1 threshold applies to UI components and graphics too. Q: Is a higher ratio always better? A: Up to a point — very high contrast can cause halation for some readers, so pure black on pure white is not automatically ideal. Q: Can I copy the hex codes? A: Yes — the copy button gives you both. ## Prayer Times Calculator URL: https://toolfyra.com/islamic-prayer-times-calculator.html Category: Faith & Lunar Calculate today's five prayer times (Fajr, Sunrise, Dhuhr, Asr, Maghrib, Isha) for 17+ cities or any coordinates, with Karachi/ISNA/MWL/Umm-al-Qura methods. Astronomical math runs in your browser — no lookup tables, no uploads. Prayer times are pure astronomy: the sun's declination and the equation of time for today's date, combined with your latitude, longitude and timezone, give every salah window. This tool implements the standard equations used by major timetables (Fajr/Isha by twilight angle, Asr by shadow factor) right in your browser — so it works for any coordinate on Earth, not just pre-listed cities, and never needs a server. Timetables differ by method (twilight angle) and by ±1–2 minutes of local rounding; mosques publish their own jamaat times, which always take priority. Q: How accurate are these prayer times? A: They use the same astronomical equations as published timetables and match to within about 1–2 minutes of local rounding. Your mosque's published jamaat timetable always takes priority. Q: Which method should I choose? A: Follow your local mosque/community: South Asia typically uses University of Islamic Sciences Karachi (18°/18°), North America ISNA (15°/15°), Europe MWL (18°/17°), Saudi Arabia Umm al-Qura. Q: Does this work offline or for any city? A: Yes — the math runs entirely in your browser, so any latitude/longitude works, even with no connection after the page loads. Q: Is my location sent anywhere? A: No. There is no geolocation request and no upload; coordinates are used locally and forgotten when you close the tab. ## Hijri Gregorian Converter URL: https://toolfyra.com/hijri-gregorian-converter.html Category: Faith & Lunar Convert any date between the Hijri (Islamic) calendar and the Gregorian calendar in both directions, instantly in your browser. Uses the standard tabular civil calendar — free, no signup, nothing uploaded. The Hijri calendar is lunar: 12 months of 29–30 days, about 354 days a year. This converter uses the standard tabular (civil) conversion used by most date libraries, computing through the Julian day number so both directions stay consistent. Because real-world Hijri dates are confirmed by moon sighting, printed calendars can differ by ±1 day — the tool states this honestly rather than pretending to false precision. Q: Why can the result differ by a day from my calendar? A: Official Hijri dates follow actual moon sighting; the tabular calendar is a fixed arithmetic approximation. A ±1 day difference is normal and expected. Q: Which years are supported? A: Any reasonable year in both calendars — the conversion is mathematical, not a lookup table. Q: Is anything stored? A: No. The conversion runs entirely in your browser. ## Faraid Share Calculator URL: https://toolfyra.com/faraid-inheritance-calculator.html Category: Faith & Lunar Estimate Qur'anic inheritance shares for common family configurations (spouse, sons, daughters, parents) with the simplified Faraid rules — computed instantly in your browser, clearly labeled as a starting point, not a fatwa. Faraid fixes specific shares: a husband takes 1/2 (no children) or 1/4 (with children); a wife 1/4 or 1/8; the mother 1/6 when there are children (else 1/3 of what remains in some cases); the father 1/6 plus residue when there are children; daughters without sons take 1/2 (one) or 2/3 (two or more), and sons turn the children's portion into residue with a 2:1 male-to-female split. This tool implements those core rules for the most common configurations and shows the maths transparently. Real estates involve siblings, debts, wills (wasiyyah up to 1/3) and school differences — so it is deliberately labeled a learning aid: confirm every real distribution with a qualified scholar or Sharia court. Q: Is this a fatwa? A: No — it is a learning aid implementing the standard fard rules for common cases. Real estates must be confirmed by a qualified scholar or Sharia court. Q: What about debts and wasiyyah? A: In fiqh, funeral costs, debts and a valid will (up to one-third) are settled before distribution; this tool splits the remaining estate only. Q: Why do my numbers change when I add a father? A: The father is both a fard heir (1/6 with children) and a residuary — adding him changes who absorbs the remainder. ## Ring Size Converter URL: https://toolfyra.com/ring-size-converter.html Category: Style & Shopping Measure your finger with a string or an existing ring, enter millimetres, and get your ring size in US, UK and EU systems instantly. Free, private, works on any device — the string method needs no special tools. Ring sizing systems are just different labels on the same physical measurement: EU size equals the inner circumference in millimetres, while US and UK sizes step along fixed charts. Enter either the circumference (string method) or the inner diameter of a ring that fits (× π = circumference) and the tool matches the nearest standard size in every system, telling you when you fall between sizes so you can size up for wide bands. Q: How do I measure without a ring sizer? A: The string method: wrap, mark, measure with any ruler. Measure in the evening when fingers are at their largest. Q: US vs UK vs EU — what's the difference? A: EU = circumference in mm; US = numbered 3–13; UK = lettered F–Z. Same finger, three label systems. Q: What if I'm between sizes? A: Size up for bands wider than 6 mm; size down only for very thin stacking rings. ## Steps to Calories Calculator URL: https://toolfyra.com/steps-to-calories-calculator.html Category: Health & Fitness Convert your daily steps into calories burned using your weight, height (stride) and walking pace. Honest MET-based math, instant and private — no app, no account, nothing uploaded. Calories from walking scale with distance and body mass: distance = steps × stride length (estimated from height as ~0.415×height for women, 0.415×height for men average 0.413), then energy ≈ 0.5 kcal per kg per km at a moderate pace, adjusted upward for brisk pace using standard MET values (2.8 stroll, 3.5 moderate, 4.3 brisk, 5.0 very brisk). This is the same method fitness researchers use for population estimates — accurate enough for planning, not for clinical use. Q: How accurate is step-to-calorie math? A: Within ~10–15% for level walking — the same MET method used in published compendia of physical activity. Hills, wind and individual gait shift real numbers. Q: What stride length is used? A: Estimated as ≈ 0.413 × height, the population average; if you know your measured stride, the tool lets you override it. Q: Does this count running? A: This tool is walking-focused; running burns roughly 2× per km — use our calories-burned tool for running METs. ## Standard Drink / Units Calculator URL: https://toolfyra.com/standard-drink-calculator.html Category: Health & Fitness Enter any drink's volume and ABV to see UK alcohol units, US and Australian standard drinks — the plain math behind the guidelines. Educational, instant, private; no judgement, no uploads. Pure alcohol mass = volume (ml) × ABV% × 0.789 g/ml. UK units = grams ÷ 8; US standard drink = 14 g; Australian = 10 g. Guidelines (UK: ≤14 units/week for everyone; US: ≤2/1 drinks per day for men/women) are public-health references, not medical advice. This tool is deliberately educational: it shows the arithmetic so labels and menus stop being opaque. If alcohol is a concern for you, talk to a healthcare professional. Q: Why do US and UK numbers differ? A: They define different 'standard' amounts (14 g vs 8 g per unit) — the underlying alcohol mass is identical; we show both. Q: Is this medical advice? A: No — educational arithmetic based on public guidelines. Personal limits are a medical conversation. Q: Does ABV matter more than volume? A: Both multiply together: a 5% pint and a 13% large wine glass can carry the same alcohol — the tool makes that visible. ## Life in Weeks Visualizer URL: https://toolfyra.com/life-in-weeks.html Category: Health & Fitness Visualize a 90-year life as 4,680 weekly boxes with the weeks you've lived filled in — the famous perspective exercise, rendered privately in your browser from just your birthdate. Popularized by Tim Urban's 'The Tail End' and many stoic-writing traditions, the grid makes abstract time concrete: 90 years × 52 weeks = 4,680 boxes. This version renders it on canvas (fast, no uploads), marks lived weeks and this week, and labels milestones. It uses a 90-year horizon as a common planning frame — it is a perspective exercise, not a life-expectancy prediction for you personally. Q: Is this predicting how long I'll live? A: No — 90 is a chosen horizon for perspective, not a personal forecast. Q: Why weeks instead of years? A: 52 boxes per year makes remaining time feel real in a way 60 yearly boxes never does — that discomfort is the point of the exercise. ## Paint Coverage Calculator URL: https://toolfyra.com/paint-coverage-calculator.html Category: Home & Decor Enter room dimensions, doors and windows, and coats — get the exact paint litres (and US gallons) you need using real coverage rates. Free, instant, private; stops you over-buying tins. Paint tins state coverage per litre (typically 10–13 m²/L for wall emulsion, less for rough surfaces). The tool computes net wall area from perimeter × height minus doors (≈1.9 m² each) and windows (≈1.5 m² each), multiplies by coats, divides by your tin's coverage and adds 10% cutting/patching allowance — the same math professional decorators use for estimates. Q: What coverage should I use? A: Check the tin: most emulsions are 10–13 m²/L. Textured or dark walls: use 8 and add a coat. Q: Should I paint the ceiling too? A: Add its area (length × width) as an extra surface if using the same product — or use our area converter for odd shapes. Q: Why 10% extra? A: Cutting-in, roller splash and touch-ups always consume more than flat-area math suggests. ## Tile & Grout Quantity Calculator URL: https://toolfyra.com/grout-tile-calculator.html Category: Home & Decor Enter the area and tile size to get tiles needed (with 10% waste), boxes to buy, and grout in kg using the standard joint-width formula. Free, instant, in your browser. Tile count = area ÷ tile area × 1.10 waste (15% for diagonal layouts). Grout follows the industry formula: kg/m² = (tile length + width) ÷ (length × width) × joint width × tile thickness × 1.6 (all in mm), which accounts for the void volume around each tile edge. Boxes round up to whole packs — buying partial boxes is the classic DIY overspend. Q: How much waste allowance? A: 10% straight lay, 15% diagonal/pattern — large-format tiles need more cuts. Q: What joint width? A: 3 mm is standard for floor, 2 mm walls; rectified tiles can go 1.5 mm. ## Solar Panel Payback Calculator URL: https://toolfyra.com/solar-payback-calculator.html Category: Home & Decor Estimate how many years a rooftop solar system takes to pay for itself: system size, cost, sun hours and your electricity rate in, break-even years and 25-year savings out. Free and private. Rooftop yield ≈ system kW × peak sun hours × 365 × 0.80 performance ratio. Yearly saving = yield × tariff (plus exported surplus where net-metering applies). Payback = installed cost ÷ saving; 25-year net saving compounds with a modest annual tariff-inflation assumption you control. Quotes vary wildly by roof and region — treat this as a sanity check against salesperson numbers, which is exactly what it's for. Q: What are peak sun hours? A: Hours of 1000 W/m² equivalent light — roughly 4 in the UK, 5.5–6.5 in the Gulf/US Sun Belt. Q: Is the 0.8 performance ratio pessimistic? A: It covers inverter loss, heat, dust and wiring — industry-standard for estimates. Q: Does battery storage change this? A: Batteries add cost and usually lengthen payback; calculate them separately as backup value, not savings. ## Wedding Gift Amount Calculator URL: https://toolfyra.com/wedding-gift-amount-calculator.html Category: Gifts & Occasions A tasteful, region-aware range for wedding gift money based on your relationship to the couple and whether you attend solo or plus-one — etiquette math without the awkward group-chat guessing. Cash-gift etiquette scales with closeness (coworker → distant family → close friend → immediate family) and roughly covers your plate when attending with a guest. Regional norms differ hugely — South Asian shaadi envelopes, Gulf niyafa customs, Western 'cover the plate' rules — so the tool offers region presets and shows the reasoning, not just a number. It's guidance, not obligation: presence matters more than the envelope. Q: Is cash okay everywhere? A: In South Asia, the Gulf and increasingly the West, cash/envelope is the norm; check whether the couple has a registry preference. Q: What if I can't afford the range? A: The range is social average, not duty — a heartfelt gift within your means is always correct etiquette. ## Secret Santa Generator URL: https://toolfyra.com/secret-santa-generator.html Category: Gifts & Occasions Paste names and draw a fair Secret Santa pairing where nobody gets themselves (a proper derangement), with exclusions like couples or last year's pair. Runs locally — names never leave your browser. A fair draw is a derangement — a permutation with no fixed points — which naive 'pick a random name' gets wrong surprisingly often. This tool builds the pairing with retry-backtracking so exclusions (partners, repeat pairs) are respected, and gives each giver a private reveal code so the organizer doesn't have to DM everyone. Everything happens in your browser; share the results list, not your data. Q: What if no valid pairing exists? A: With too many mutual exclusions a perfect draw is impossible — the tool tells you instead of silently breaking a rule. Q: Can people see who they got? A: Reveal happens on your screen; copy each line and send privately, or screenshot per person. ## CSS Gradient Generator URL: https://toolfyra.com/css-gradient-generator.html Category: Developer Tools Build linear and radial CSS gradients visually: pick colors, angle and stops, watch the live preview, copy the code. Free, instant, runs entirely in your browser. Modern gradients are one line of CSS, but hand-writing color stops is tedious. This builder composes linear-gradient(angle, c1 p1, c2 p2(, c3 p3)) or radial-gradient(circle, …) with correct percentage stops, previews it at 60+ sizes of smoothness (pure CSS, no canvas needed) and copies both the shorthand background and the full background-image line. Q: Why two CSS lines to copy? A: background-image is the property purists use inside rules; background shorthand works too — pick whichever matches your codebase. Q: Can I add transparency? A: Yes — use 8-digit hex like #4f46e580 or rgba() values directly in the color inputs. ## CSS Box Shadow Generator URL: https://toolfyra.com/css-box-shadow-generator.html Category: Developer Tools Design CSS box-shadows with sliders for offset, blur, spread, color and inset — live preview on a card, copy-ready code. Free and fully in-browser. box-shadow takes x-offset, y-offset, blur, spread, color and an optional inset keyword. Getting the feel right by typing numbers is slow; this tool renders every slider move live on a sample card and emits the exact CSS line, including rgba() with your chosen opacity. Q: When should I use inset? A: For pressed/engraved UI (wells, pressed buttons). Outer shadows lift; inset pushes in. Q: Blur vs spread? A: Blur softens edges; spread grows the whole shadow footprint. ## HTTP Status Code Lookup URL: https://toolfyra.com/http-status-code-lookup.html Category: Developer Tools Search or browse every HTTP status code (1xx–5xx) with a plain-English meaning and the fix to try. Instant reference for devs and site owners — free, offline-capable, in your browser. HTTP statuses group into five families: 1xx informational, 2xx success, 3xx redirect, 4xx client error, 5xx server error. Each entry here pairs the official meaning with the practical next step (e.g. 429 = slow down / retry-after; 502 = upstream died, retry; 301 vs 308 for permanent moves with method preserved) — the context stack traces never give you. Q: 301 vs 308? A: Both permanent; 308 keeps the request method (POST stays POST) — use 308 for form endpoints. Q: 401 vs 403? A: 401 = not authenticated (login may fix it); 403 = authenticated but not allowed. ## Business Name Generator URL: https://toolfyra.com/business-name-generator.html Category: Generators Type a keyword and pick a style (modern, classic, playful, descriptive) to get 40 available-sounding business name ideas instantly. Free, private, no signup — then check trademarks before you fall in love. Strong business names follow repeatable patterns: compound words (PayPal), suffix blends (Shopify), evocative Latin/Greek roots (Lumen), or plain descriptors (The Karachi Bakers). This generator applies those patterns to your keyword across four style sets and shuffles fresh combinations on every click. Naming is free here; legality isn't automatic — always trademark-search and domain-check your shortlist. Q: Are these names trademark-free? A: No generator can promise that — search your trademark registry and domain before registering. Q: Which style ranks best? A: Descriptive names SEO faster; coined names brand better. Many winners combine both (descriptive tagline + coined brand). ## Slogan / Tagline Generator URL: https://toolfyra.com/slogan-generator.html Category: Generators Generate 30 slogan candidates from your brand name and benefit — benefit-first, rhyme, command, and contrast angles included. Free, instant, in-browser. Memorable taglines use a handful of rhetorical moves: benefit statement ('Melts in your mouth'), command ('Just do it'), contrast ('X without Y'), rhyme, alliteration, and identity ('The X for Y people'). This tool applies all six to your inputs and shuffles wording banks, so every click surfaces a different shortlist to react to. Q: How do I pick? A: Say them out loud; the one you'd put on a van wins. Test 3 on real customers before deciding. Q: Long or short? A: Under 6 words survives a logo; under 4 survives a billboard. ## Password Strength Checker URL: https://toolfyra.com/password-strength-checker.html Category: Generators Check any password's real strength: entropy bits, crack-time estimates, and breach-pattern detection (common passwords, keyboard walks, repeats) — computed entirely on your device. Nothing is ever sent anywhere. Strength = entropy: length × log2(alphabet size), minus penalties when patterns (dictionary words, '123456', keyboard rows like 'qwerty', doubled chunks) let attackers skip most guesses. This tool computes bits, translates to offline-crack time at 10 billion guesses/second (modern GPU rig), and flags the specific pattern that weakens you — all locally, so even this page never sees your secret. Q: Is it safe to type my password here? A: Safer than any online checker: the analysis is pure local JavaScript and no network request contains your input. Still, prefer testing a similar-but-not-identical password. Q: What's a good score? A: 60+ bits (≈12+ random chars or 5 random words) resists offline GPU cracking for centuries. ## Inflation Impact Calculator URL: https://toolfyra.com/inflation-impact-calculator.html Category: Money & Business See what today's savings will actually buy in 1–30 years at any inflation rate, and the yearly amount needed to preserve purchasing power. Plain math, instant, private. Purchasing power decays geometrically: real value = amount ÷ (1 + inflation)^years. At 6% inflation, money halves in buying power roughly every 12 years (rule of 72). This tool shows the curve year-by-year and the annual return your savings must beat just to stand still — the number banks rarely volunteer. Q: What rate should I use? A: Your country's central-bank target (2–3%) is optimistic; recent actuals in many markets ran 6–30%. Test both. Q: How do I beat it? A: The required return shown is the bar — savings accounts below it lose real value every year. ## Split Bill by Item URL: https://toolfyra.com/split-bill-by-item.html Category: Money & Business Assign each bill item to the people who had it (plus shared items everyone splits) and get exact per-person totals with tip. No app, no signup — settles the dinner math instantly in your browser. Even splits punish light eaters. This tool splits each item only among the people ticked for it, divides shared items across everyone, applies tip pro-rata, and shows each person's total — the same arithmetic settlement apps charge for, done privately on your device. Q: How is tip applied? A: Pro-rata on each person's subtotal, so big eaters tip more. Q: Can one person own multiple items? A: Yes — tick them on each item they ate. ## Tire Size Calculator URL: https://toolfyra.com/tire-size-calculator.html Category: Travel & Documents Compare two tire specs (e.g. 205/55R16 vs 225/45R17): overall diameter, width, and the exact speedometer error percentage. Free, instant, in your browser — for safe plus-sizing. A tire code 205/55R16 means 205 mm section width, sidewall = 55% of width, on a 16-inch rim. Overall diameter = rim + 2×sidewall. Changing diameter changes effective gearing and speedometer reading by the diameter ratio; the industry rule of thumb keeps the change within ±3% to protect ABS/accuracy. This tool does the full math for any two codes. Q: What's the safe limit? A: ±3% diameter change is the common guideline; beyond that, speedo, ABS and clearance need professional recalibration. Q: Does width matter? A: Width affects grip and clearance, not speedo — the tool shows both but only diameter drives the error. ## GPA Goal Calculator URL: https://toolfyra.com/gpa-goal-calculator.html Category: Calculators Enter current GPA, credits earned and credits left, and see the exact average GPA you must earn in remaining terms to hit your target — with a feasibility flag. Free and instant. Final GPA = (current×earned + needed×remaining) ÷ total credits. Solving for the needed average is one line of algebra, but students rediscover it under stress every term. This tool solves it instantly, caps it against your scale (4.0/5.0), and tells you plainly when a target is mathematically out of reach so you can adjust early. Q: It says impossible — now what? A: The math is absolute for that target; raise remaining credits (extra courses) or adjust the target. Advisors can also discuss grade-replacement policies. Q: Do weighted courses change this? A: If your school weights credits differently, use effective credit units in the inputs. ## Wallpaper Quantity Calculator URL: https://toolfyra.com/wallpaper-quantity-calculator.html Category: Home & Decor Wallpaper math is drops, not area: divide the wall into paper widths (drops), see how many full-height strips each roll yields (pattern repeat wastes Free, instant, private — runs entirely in your browser.
