How to Convert MP4 to MP3 — Extract Audio from Any Video

Pull the audio track out of an MP4 video and save it as an MP3. Perfect for podcasts, lectures, music videos and interviews. Free and instant.

You have a video but you only need the sound — a lecture you want to listen to on your commute, a podcast interview, a music video, or a meeting recording. Converting MP4 to MP3 extracts just the audio track so you can listen without watching.

Why Extract Audio from Video?

  • Listen to lectures and talks on the go without video.
  • Save podcasts from video interviews for audio distribution.
  • Extract music from music videos.
  • Create audio files from meeting recordings.
  • Reduce file size — MP3 audio is 10× smaller than MP4 video.

If your video has no audio track (like a screen recording), the tool will tell you there is nothing to extract. Only audio that exists in the video can be pulled out.
