How to Use Video Compressor

Reduce video file size directly in your browser using WebM/VP9 encoding without uploading your files to a server.

1. 1

   Select your video file

   Click the upload area to choose an MP4 or WebM file from your device. Since processing happens locally, your file is never uploaded to a server.

2. 2

   Choose your desired output resolution

   Select from Low (360p), Medium (480p), High (720p), or Original resolution. Lower resolutions will result in smaller file sizes for easier sharing.

3. 3

   Start the compression process

   Click the compress button to begin re-encoding your video using the WebM/VP9+Opus codec. The tool preserves both video and audio quality while shrinking the file size.

4. 4

   Download your compressed WebM file

   Once the re-encoding is complete, save the optimized WebM file to your device. Your new video is now ready for uploading or sharing with a reduced footprint.
