# Video to MP3

Use this page when you have a video and want its sound as an MP3, whatever the container. It reads MP4, MOV, WebM, MKV and AVI in your browser, with no upload. The picture is not decoded, only the sound. The first run downloads a 32 MB engine from a public CDN.

Runs on your device

## How it works

1. Choose the video, whichever format it is in.
2. Choose a quality for the MP3.
3. Press convert to MP3.
4. Save the MP3 to your device.

## Key facts

- **Tested containers**: MP4, MOV, WebM, MKV and AVI.
- **Tested audio inside**: AAC, Opus and MP3. Other codecs may work, but we have not tested them.
- **Several tracks**: Only the first audio track is converted.

## Common uses

- Saving a lecture from a video folder with mixed formats.
- Listening to long recordings without keeping the screen on.
- Getting a backing track from your own video project.

## Questions

### Can it take a link to an online video?

No. It only works with files already on your device, and it does not download from websites.

### What happens to subtitles?

They are left out. An MP3 holds sound only.
