## FAQ

### Does extracting lose audio quality?

M4A copies the original track straight out of the video without re-encoding, so it is identical to the source. MP3 re-encodes, and WAV decodes to uncompressed audio, which is much larger.

### Which video formats are supported?

Common ones such as MP4, MOV, MKV and WebM. Decoding is done by FFmpeg running locally in your browser, so nothing needs converting first.

### Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Files never leave your computer and are discarded when you close the page.

### Do I need to sign up or pay?

No. The site is completely free, requires no account, has no usage limits and adds no watermarks.
