How to Extract Audio From a Video (MP4 to MP3)

Whether it is a recorded lecture, an interview or a song from your own video, extracting the audio takes a few seconds and keeps the original quality.

Extract the audio

1. Open Video to MP3 and drop the video.
2. Choose MP3 (plays everywhere) or M4A (copies AAC audio without re-encoding — fastest and lossless).
3. Click Convert and download.

Keep only part of it

Cut the result with the MP3 cutter, or trim the video first with Trim video.

Which bitrate?

128 kbps is plenty for speech, 192 kbps for music, 256–320 kbps for the best quality. The audio cannot get better than it was in the video, so very high bitrates only add size.
