Can I compress an MP4 video on Windows without downloading an app?

Yes. The tool on this page runs inside Chrome, Edge, and Firefox on Windows 10 and 11, so nothing needs to be installed.

Is my video uploaded when I compress it on PC?

No. Compression runs locally on your PC using your browser's WebCodecs encoder, keeping your file private.

Why does my compressed video look blurry?

If you choose a very small target size for a long video, the encoder has to drop detail. Lowering the resolution to 720p or 480p helps keep it clear.
