How to convert MP4 to MP3

  1. Choose the video. Select an MP4 or other video file from your device, up to 50 MB.
  2. Pick a format. Keep MP3, choose another audio format, or choose All formats to get every one in a ZIP.
  3. Convert. Select Convert and wait a few seconds while the audio is extracted.
  4. Save the file. The audio file or ZIP downloads to your device automatically.

Which audio format should I pick?

MP3

192 kbps. Plays on every phone, computer, car stereo and music app — the safe choice.

M4A / AAC

192 kbps. Slightly better sound than MP3 at the same size; ideal for iPhone and iTunes.

WAV / FLAC

Lossless copies of the video's sound, for editing or archiving. FLAC is smaller than WAV.

OGG / Opus / AC3

OGG and Opus (128 kbps) are compact open formats for web and voice; AC3 suits home-theatre setups.

What to expect

  • Videos can be up to 50 MB.
  • The video needs a sound track — a silent video can't be converted.
  • The audio is only as good as the video's original sound; converting can't add quality.
  • This page works with files on your device. For a public video link, use Video to MP3.
