Extract audio from a video: MP4 to MP3 and more

Extract Audio takes the sound track out of a video and saves it as MP3, M4A, WAV, OGG, FLAC or Opus. Do several videos at once and download them together as a ZIP.

It works with MP4, MOV, MKV, WebM, AVI and phone videos, and it all happens in your browser: a 400 MB video gives up its sound in about ten seconds on a laptop.
