Private MP4 to WAV conversion

Extract the full uncompressed audio track from an MP4 video as a WAV file.

Conversion is powered by FFmpeg compiled to WebAssembly and runs locally. 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.
