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.
