About the Compress Video
Compress Video re-encodes a clip at a lower bitrate to shrink the file, so it fits an upload limit or sends more easily. Choose a smaller-file or higher-quality balance and it does the rest. All processing happens in your browser with ffmpeg (WebAssembly), so your video is never uploaded — it is private and free with no watermark. It works best on short clips, since the work runs on your device rather than a server.
Compression is a trade-off: a smaller file means lower quality. Because it re-encodes on your device, it is best for short clips; a long, high-resolution video may be slow. For a big file, trimming it first also helps.
Frequently asked questions
Is my video uploaded?
No. Compression runs entirely in your browser; your video stays on your device.
How much smaller will it get?
It depends on the clip and the level you choose. Higher compression means a smaller file but lower quality.
Why is it slow?
Compression re-encodes the whole video on your device rather than a server, so longer or higher-resolution clips take more time.
Will the quality drop?
Some, yes. Compression works by lowering quality to save space. The balanced setting keeps a good compromise.
