Compress and reduce video file size directly in your browser — no upload, no account needed. Choose from Low (360p), Medium (480p), High (720p), or Original resolution. The tool re-encodes your video using the WebM/VP9+Opus codec entirely on your device, preserving both video and audio. Ideal for shrinking large MP4 or WebM files before sharing or uploading. Output is WebM format.
Reduce video file size directly in your browser using WebM/VP9 encoding without uploading your files to a server.
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.
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.
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.
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.
