Compress video

Make videos small enough to share using a genuine FFmpeg engine that runs inside your browser. The first job downloads the engine once (~32 MB) and it is slower than a native app, but your footage never leaves your device.

How to compress video

  1. Drop the video you want to compress.
  2. Choose a quality level and output resolution, and keep or drop the audio.
  3. Run, and the engine downloads once, then encodes on your device.
  4. Download the compressed MP4.

Frequently asked questions

Is my video uploaded to a server?

No. Compression uses an FFmpeg engine running inside your browser, so the video never leaves your device.

Why is the first job slow to start?

The FFmpeg engine (~32 MB) downloads once on first use. After that it is cached, and encoding is on-device, so it is slower than a native app.

What format do I get out?

You get a compressed H.264 MP4, which plays virtually everywhere.
