Compress videos
Shrinks WebM and MKV videos in your browser by re-saving them at a lower quality. MP4, MOV, and AVI need the FFmpeg core or a conversion to WebM first.

Accepts MP4 · WEBM · MOV · AVI · MKV
Compressing works with WebM and MKV videos. This site can't re-save MP4 or MOV files in the browser yet, so to make one smaller, convert it to WebM and turn the quality down.
