The fastest path to a smaller file
Most file-size reduction comes from three levers: shorter duration, lower resolution, and lower bitrate. This browser tool focuses on resolution and bitrate.
Best settings and limits
Best first try
Use 720p for a balanced result. Use 480p when size matters more than sharpness.
When this may fail
If a video is many minutes long, compression alone may not be enough. Shortening the clip can make a bigger difference.
Privacy boundary
The selected video file stays on your device while the tool creates the output.
Frequently asked questions

Some quality tradeoff is normal. Higher compression means smaller files but more visible loss.
Is this private?
Yes. The source file stays in the browser tab during local processing.
Which output format do I get?
The output is an MP4 for broad compatibility.
