Features

MP4 already plays almost everywhere, so people convert it mainly when an editor, website or older device asks for a different format, or when they only need the sound. This page does exactly that conversion: add your MP4 file and BigQTools returns the sound as MP3, with the same file name and a new extension. For compressed formats you can choose 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality; WAV and FLAC always keep the full signal.

  • Preset for MP4 to MP3, so the right format is always used.
  • Bitrate choices of 128, 192 and 320 kbps for compressed formats.
  • Also takes the soundtrack from video files such as MP4, MOV and MKV.
  • The file name is kept; only the extension changes to .mp3.
  • Files travel over HTTPS and are deleted automatically after 2 hours.

Frequently asked questions

Will converting MP4 to MP3 affect the sound quality?

Lossy formats such as MP3, M4A and OGG drop detail you rarely hear at 192 or 320 kbps. WAV and FLAC keep everything that is in the source, but no format can restore quality the MP4 file never had.

What is the difference between MP4 and MP3?

MP4 is the most widely supported video format: it plays on nearly every phone, computer, smart TV and website. MP3 is the most universal audio format, playable on virtually every phone, computer, car stereo and speaker.

Can I convert MP4 to other audio formats?

Yes. The “Convert audio” page takes the same file and offers MP3, M4A, WAV, FLAC, OGG and M4R.

Can I convert audio from a YouTube or Spotify link?

No. Streaming links are not supported for copyright reasons. A file on your device, in Google Drive or behind a direct download link works.
