Binary ↔ Text Translator — Binary, Hex & Decimal

How to use

1. Paste text to encode, or binary/hex/decimal code to decode.
2. Leave the mode on Auto-detect or force a direction from the dropdown.
3. Copy the result — the byte count shows in the status line.

About this tool

One box, every direction: paste plain text and encode it to 8-bit binary, hexadecimal, or decimal byte values; paste any of those three back in and the auto-detector figures out what you gave it and decodes to text. Manual override selects force a specific interpretation when you know better than the heuristic — useful for hex strings like “babe” or decimal lists that could also look like something else. Encoding uses the browser's UTF-8 TextEncoder, so emoji, accents, and non-Latin scripts convert correctly with an honest byte count (that emoji costs four bytes) instead of the old ASCII-only lie. Computer-science students, embedded developers reading UART dumps, and the terminally curious all get instant answers; every conversion happens locally with no network call at all.
