Which videos can I compress?

MP4, MOV, MKV, WebM and AVI. Each file comes back in its own format, just smaller.

Does compressing videos reduce quality?

Lossy formats trade a little quality for a much smaller file, and Balanced is tuned to look or sound the same for most uses.

Can I compress videos to a specific size?

Yes, for MP4, MOV, MKV, WebM and AVI: set a target size or a percentage to reduce by.

Are my videos uploaded?

All videos are compressed right in your browser with WebAssembly, so nothing is uploaded.

Can I compress several videos at once?

Yes. Add up to 5 files at a time without an account, 10 with a free account and up to 500 on paid plans, mixing formats if you like, then download them individually or as one ZIP.
