💡 Performance Diagnostic Guide:
- Compression rate relies on your CPU rendering canvas elements in real-time.
- For optimal sync, keep the tab active. Minimizing the window pauses canvas captures.

What is Video Compressor?
Our client-side Video Compressor scales and transcodes your video files directly in your web browser. By capturing canvas streams at custom dimensions (from 0.25x to 1.0x) and utilizing MediaRecorder API encoding controls, you can adjust the output bitrate to shrink file sizes.
This tool is 100% private. Since there are no server-side uploads or third-party cloud connections, your media remains secure on your machine.
