Who is it for?

How does it work?

Simply drag and drop your video file onto the page. The tool uses FFmpeg, an open-source software, running directly in your browser to apply H.264 compression. After processing, you can compare the original and compressed versions side by side and download your file. No uploading, no waiting for servers.
