How to extract audio from a video

  1. Drop the video in. Or several. MP4, MOV, WebM, or an audio file you want converted.
  2. Pick MP3 or WAV. MP3 at 192 kbps is the default and right for almost everything.
  3. Download. The audio file has the video's name with the new extension.

Questions people ask

Which files can I extract audio from?

MP4, MOV, WebM, M4A, MP3, WAV, OGG, anything your browser can decode. A video with no audio track shows an error rather than an empty file.

MP3 or WAV?

MP3 for anything you'll share, upload or keep: a tenth of the size and plays everywhere. WAV is uncompressed, for editing or archiving when you want every bit of the original.

Which MP3 bitrate?

128 kbps for speech and podcasts, 192 for music you'll listen to casually, 320 for music you'll keep or edit. Higher than the source can't add quality: a video with 128 kbps AAC audio is best extracted at 128 or 192.

How long a file can it handle?

The audio is decoded into memory, at about 10 MB a minute for stereo. Up to an hour works on a laptop; on a phone stay under 20 minutes.
