About this tool

Keep just the audio of a video: a lecture to listen to on the go, the song from a clip, an interview for transcription or the voice from a screen recording. Drop an MP4, MOV, WebM or MKV, choose MP3, M4A or WAV and download. When the video's sound is already AAC and you choose M4A, it is copied as is - instant and without any quality loss. The video is processed by your browser and never leaves your device.

How to use it

  1. 1 Choose or drop a video.
  2. 2 Pick MP3 (plays everywhere), M4A (smallest, no loss when the video uses AAC) or WAV (for editing).
  3. 3 For MP3 and M4A, choose the quality.
  4. 4 Tap 'Extract and download'.

Frequently asked questions

How do I turn an MP4 into an MP3?

Drop the MP4, keep MP3 selected and tap 'Extract and download'. You get an MP3 with the video's sound.

Which format keeps the original quality?

M4A: most phone and web videos use AAC audio, which is copied into the M4A without re-encoding.

Can I extract audio from long videos?

Yes. Copying AAC to M4A is quick even for hours of video; MP3 and WAV take longer because the sound is re-encoded.

Is the video uploaded?

No. Everything happens in your browser.
