How to use Video Compressor
- Drop a video file into the upload area.
- Choose a compression level (Balanced is right for most cases).
- Click Process video and download the compressed MP4.
Frequently asked questions
Is this video compressor really free?
Yes — free with no account, no watermark, and no length limit.
How much smaller will my video get?
It depends on the source, but 40-80% reductions are typical for phone footage. The size before and after is shown next to the download.
Which level should I pick?
High quality keeps the original resolution; Balanced caps the long side at 1280px; Smallest caps it at 854px and compresses harder. For messaging apps, Balanced or Smallest is usually plenty.
Why is compression slower than trimming?
Trimming copies the stream without touching it; compression re-encodes every frame, which takes roughly as long as the video itself (or more) — all locally on your device.
Are my files uploaded to a server?
No. All processing happens locally in your browser using WebAssembly. Your files never leave your computer — close the tab and nothing remains.
