About this tool

TikTok borders, screen-recording toolbars, ugly edges from a re-save — cropping fixes all of them. Enter exact pixel values (width, height and the x/y offset of the top-left corner) or pick a preset that trims 5% or 10% from every side automatically — the presets use resolution-aware expressions, so they work the same on 4K landscape or vertical phone footage. The FFmpeg engine (one-time ~30 MB engine load) re-encodes locally at high quality; nothing is uploaded. Your file never leaves this page — processing runs in your browser via WebAssembly; nothing is uploaded and the file is dropped from memory when you close the tab.
