Compress videos online

Re-encode your videos at a quality you choose — right in your browser, with nothing uploaded. Keep each video in its own format, or pick MP4 or WebM to compress it into. The tool is built for short clips: compression happens on your device, so long videos will take a long time. MOV and MKV videos are saved as MP4.

How it works

Compressing videos, simply explained

The tool decodes each video and saves it again at the quality you choose: lower quality usually makes a smaller file, higher quality keeps more detail. Keeping the original format saves an MP4 as an MP4 and a WebM as a WebM; MOV and MKV videos are saved as MP4, because those formats cannot be written here. Only the first audio track is kept, and subtitles are not carried over. HDR videos are converted to standard colour. Every result shows its real before-and-after sizes, even when a re-encoded file comes out larger.

Private by design.
