Frequently asked questions
How does browser-based compression work?
The tool uses the MediaRecorder API to re-encode your video through an HTML5 canvas at a lower bitrate. This runs entirely in your browser using VP8/VP9 codecs.
What format is the output?
Compressed videos are output as WebM (VP9) format, which is widely supported in browsers and most video players.
Is there a file size limit?
The tool supports videos up to 500MB. Larger videos may cause browser memory issues. For very large files, consider desktop software.
Why does it take as long as the video?
The video plays through at 1x speed while the browser captures and re-encodes each frame. This is a limitation of the browser MediaRecorder API.
Are my videos uploaded?
No. All compression happens locally in your browser. Your videos never leave your device.
