About

No ads. No tracking.
No cloud.

Your video never leaves your device. We compress it right here, in your browser, using FFmpeg compiled to WebAssembly.

Why? Because compression is solved. FFmpeg has been doing this for 25 years. There's no reason to upload your private videos to some server, wait in a queue, and download a watermarked result.

How it works

FFmpeg.wasm runs entirely in your browser. The ~30 MB engine downloads once and gets cached. After that, compression works offline.

No account. No login. No "premium tier." No "3 free conversions." Just pick a video and compress it.

Open source

Every line of code is public. Audit it yourself.

Built with FFmpeg, spite for ads, and a belief that tools should be free.
