Compress Video
Beat file size limits — processed on your own device.
🔒 Files never leave your deviceWhat this tool does
This tool reduces video file size by lowering the resolution and quality (bitrate). Use it when you hit email, messenger or upload size limits. Your browser plays the video once while re-recording it, so everything happens on your own device without installing anything.
How to use
- Add the video you want to shrink.
- Choose resolution and quality (720p · Medium works for most).
- Click 'Compress' and keep this tab open until it finishes.
FAQ
How long does it take?
About as long as the video — it's re-recorded while playing. A 1-minute video takes about a minute.
Can I switch tabs?
Keep this tab visible while compressing. Browsers slow down background tabs, which can make the video stutter.
Is my video uploaded?
No. Everything happens in your browser.
What format is the output?
MP4 if your browser supports it, otherwise WEBM. The latest Chrome or Edge is recommended.
Tips
- Resolution refers to the short side — for vertical videos, '720p' makes the short side 720px.
- It takes about as long as the video plays, so keep this tab visible until it finishes.
- If the result is bigger than the original, you'll see a note. Try one step lower resolution or quality.
