Nothing is uploaded

Your video is processed on your own device with WebAssembly — a browser build of FFmpeg. Private by architecture, not by promise.

No waiting on uploads

A 1 GB file starts processing instantly. Upload-based tools spend most of their time just moving your file to their servers.

Free, no strings

No watermarks, no sign-up walls, no trial limits. Because processing runs on your device, there's no server bill to pass on.
