Video Compressor
Compress video files online for free. Reduce MP4 and other video file sizes right in your browser and download a smaller WebM. Nothing is uploaded.
Works best with MP4 (H.264) videos your browser can play. Everything is processed on your device; nothing is uploaded.
Note: this tool re-encodes your video in your browser and saves it as a WebM file. Browsers cannot create MP4 files directly, so MP4 output is not possible here. Very large or high-resolution videos may take a while and use significant memory.
