Video optimization

What does Video Compressor do?

Large video files are hard to email, message, or embed on a page. This compressor reduces video bitrate and dimensions so files become smaller and easier to share.

Compression uses a local WebAssembly engine, so the video stays on your device the whole time.

Shrink video files for email, chat, and web delivery.
Reduce bitrate and dimensions to control quality and size.
Process video locally without uploading it.

Common use cases

Making a video small enough to email
Compressing clips for a website
