FFmpeg.app is a web-based front end to FFmpeg, the free and open-source application and libraries for processing of video and audio files. Its purpose is to serve as an easy front-end to this powerful tool, so anybody can discover and use it with no setup (or command-line access) necessary.

You can find the public version of the FFmpeg.app front-end at ffmpeg.app, and a development "staging" version at dev.ffmpeg.app.

All processing done by FFmpeg.app runs in the browser, without ever leaving one's computer. No data is tracked.

FFmpeg.app uses ffmpeg.wasm by Jerome Wu to be able to run FFmpeg as a library inside a web browser.

FFmpeg.app is not associated with, nor endorsed by, the FFmpeg project.
