Compress a video
Shrink a video to a target size or by quality.
Drop the video you want smaller
or click to choose (.mp4, .mov, .webm, .mkv, .avi). Up to 100 MB per file.
The tool works out the bit rate so the result fits the size you set.
We will read the length of the video once the file is uploaded.
On phone video, scaling to 1080p saves the most megabytes.
Fewer frames per second means a smaller file. On a screen recording you barely notice; on sport you do.
Sound takes little space, though on a long video it still shows.
The video is processed in your browser, nothing is uploaded. The first run downloads about 32 MB of the computing core, after that everything runs without waiting. Longer files take a few minutes.

How to make a video smaller
Drop the file in, choose how much compression you want and, if it helps, a lower resolution. The video is re-encoded in your browser and you download the result. Nothing is sent anywhere, so no other server ever touches it.
- Light: for archiving and further editing, the difference is hard to spot.
- Medium: the usual choice for email, the web and sharing.
- Heavy: when the file has to come in under a limit whatever it takes.
Frequently asked questions
Why does this take longer than images?
The video has to be re-encoded from end to end, and your browser does the computing, not a server. A minute of 1080p costs roughly a minute of work, so give longer files time.
What shrinks a file the most?
The resolution. Phone video is often 4K, and scaling to 1080p cuts most of the bulk without showing on a display. Only after that is heavier compression worth reaching for.
How large a file can it handle?
Up to 200 MB. The limit is not in the tool but in the browser's memory: with larger files the tab dies before the computation finishes.
