Private MOV to WebM conversion

Conversion is powered by FFmpeg compiled to WebAssembly and runs locally in your browser. The engine downloads once on first use, then your media is processed on your own device — nothing is uploaded.

Is there a file size limit?
The only limit is your device's memory, since processing happens in your browser rather than on a server.
Are my files uploaded?
No. Everything is processed locally in your browser, so your files never leave your device.
