# Convert MP4 to MP3 online (extract audio free)

Pull the audio out of an MP4 and save it as MP3, right in your browser. Your video never leaves your device.

1

## Questions & answers

### Will the MP3 lose audio quality?

Export at 192-320kbps for near-transparent quality. Lower settings shrink the file but soften the sound.

### Does my MP4 get uploaded anywhere?

No. The audio is extracted in your browser, your video never leaves your device, and we keep nothing.

### Can I grab audio from just part of the video?

Extract the full track here, then trim it in any editor. To cut the video first, use the [video trimmer](/tools/trim-cut-video).

### What about WAV or AAC output?

Use the [video to audio converter](/tools/video-to-audio-converter) to export WAV, AAC, or FLAC instead.
