How to convert MP4 to MP3
- Choose your video (MP4, MOV, WebM and others) or audio file.
- Pick the MP3 quality and stereo or mono.
- Wait for the conversion, listen to the preview and press Download MP3.
Which bitrate should I choose?
| Bitrate | Size per minute (stereo) | Good for |
|---|---|---|
| 128 kbps | about 1 MB | Speech, podcasts, voice notes |
| 192 kbps | about 1.4 MB | Most music |
| 256 kbps | about 1.9 MB | High-quality music |
| 320 kbps | about 2.4 MB | The best MP3 quality |
Converting can’t add quality that wasn’t in the original, so a higher bitrate than the source won’t sound better.
Very long videos need a lot of memory. If your browser struggles, try a shorter clip. Only convert videos you own or have permission to use.
