About MediaToolbox

MediaToolbox is a free toolbox for video, audio and image files — compress, convert, trim, rotate and extract, all without uploading anything.

Why we built it

Most "free" media tools are upload farms: you send your files to a server, wait in a queue, and get a watermarked result with size limits. Modern browsers are powerful enough to do all of this locally. So we built tools that never touch a server.

What runs where

Image tools use the Canvas API. Audio tools use Web Audio. Video tools use an in-browser WebAssembly build of ffmpeg. Everything executes on your own device.

Free forever

All 17 tools are free, with no accounts, no watermarks and no file-size limits. The site is supported by unobtrusive display ads.
