Why use a browser-based video compressor?

Traditional online video compressors require you to upload your video to a remote server — which raises serious privacy concerns, especially for personal footage, screen recordings of sensitive work, or any video containing private information. With SwissTools Video Compressor, your video never leaves your device. Compression is handled entirely by FFmpeg compiled to WebAssembly, running natively inside your browser.

There's no account to create, no file size quota to hit, and no waiting in a server queue. Since everything runs locally, compression speed depends only on your own device.
