Compress video online
Shrink a video right in your browser. The file is never uploaded and never leaves your device.
How it works
- Pick a video file — it stays on your device and is never uploaded.
- Choose a compression level and resolution. Lower resolution means a smaller file.
- Press Compress video and download the result.
Limitations
Compression uses your browser's own codecs, so speed depends on your device. On phones the tab may close on very large files, so big videos are safer to process on a computer. MP4, MOV, WebM, MKV and other common formats are supported.
