Shrink a clip that’s too big to send or upload. Re-encode it at a lower bitrate and, if you like, a smaller resolution — right in your browser, with sound kept intact.

Choose videoDrag a clip onto the box or click to browse. It loads instantly — no upload.
Pick a compression level and, if you want, downscale the resolution to shrink it further.
Compress and download a smaller WebM. The result shows exactly how much you saved.
Re-encoding at a lower bitrate typically cuts a big clip down to a fraction of its size.
Four strength levels plus optional downscaling let you balance quality against file size.
The soundtrack is carried through the re-encode, so your compressed clip still has sound.
Compression runs entirely on your device — your footage is never uploaded.
This compressor plays your clip through once, redraws each frame onto a canvas, and records the result with the browser’s built-in encoder at a lower target bitrate. Because it renders in real time, a 30-second clip takes roughly 30 seconds — the trade-off for keeping everything private and on-device.
File size is mostly a function of bitrate — the amount of data used per second of video. Dropping from “Light” to “Strong” lowers that target and shrinks the file; going further with a smaller resolution compounds the savings.
Compressed clips are saved as WebM (VP9/VP8), a modern, widely-supported format that plays in every major browser and on most platforms. For maximum compatibility with older software, you can convert the WebM afterwards.
Compress, trim, extract frames and make GIFs — all in your browser.
