How to compress a video
Add your video
Drop in an MP4, MOV, WebM or MKV (up to 500 MB). The first run downloads a one-time ~30 MB engine, then it's cached.
Set the quality
Drag the Quality slider between Smaller file and Best quality.
Choose a resolution
Keep Original, or downscale to 1080p, 720p or 480p to shrink further.
Compress & download
Click Compress, then Download MP4 to save your smaller video.
Frequently asked questions
- What formats can I compress?
- MP4, MOV, WebM, MKV and more, up to 500 MB. The result is always an MP4 (H.264).
- Will it lose quality?
- You control it with the Quality slider and resolution — lower settings make a smaller file with softer detail. Files over 150 MB may take a few minutes.
- Are my videos uploaded?
- No — compression runs entirely in your browser; nothing is uploaded. A one-time ~30 MB engine downloads on first use and is cached.
