Extract audio from video

Pull the audio track out of a video file and save it as a WAV — MP4, WebM, MOV and friends.

Decoded and re-encoded in this browser. The file never leaves your device.

Extracts the audio track to uncompressed 16-bit PCM WAV — expect about 10 MB per minute of stereo. Up to 30 minutes and 400 MiB. DRM-protected video is not supported.

How to use

  1. Choose a video file.
  2. Extract the audio.
  3. Download the WAV.

What it supports

Decodes whatever the browser can play (MP4/WebM/MOV/MKV, and plain audio files too) and re-encodes as uncompressed 16-bit WAV — roughly 10 MB per stereo minute. Up to 30 minutes and 400 MiB. Multi-channel audio is mixed down to stereo. DRM-protected video fails at decode.
