# Convert WebM to MP3

Browser recorders, web meeting tools and many downloads save WebM, which phones, car stereos and audio editors often will not play. Keep just the sound as an MP3.

**Quick answer:** To convert WebM to MP3, add the .webm files and press Convert to MP3: the Opus or Vorbis sound is decoded and saved as a 192 kbps MP3, about 1.4 MB per minute, and the video is dropped. Audio-only .weba recordings work too. Everything runs in your browser; nothing is uploaded.

## How to use it

1. Choose the .webm or .weba files.
2. Keep 192 kbps, or choose 128 kbps for speech or 320 kbps for music.
3. Press Convert to MP3.
4. Download the MP3s, as a ZIP if there are several.

## Where WebM comes from

- **Browser recordings**: sites and extensions that record your screen, camera or microphone usually save WebM, because Chrome and Firefox record it natively.
- **Voice recorders on the web** often save audio-only WebM (sometimes named .weba).
- **Web videos** saved from sites that stream in WebM.

The sound inside is Opus or Vorbis, which many devices outside the browser cannot play. MP3 plays everywhere.

## Pick the bitrate by content

| Recording | Bitrate | Per minute |
| --- | --- | --- |
| Meetings, lectures, voice memos | 128 kbps | about 0.96 MB |
| Mixed speech and music | 192 kbps | about 1.4 MB |
| Music | 256 to 320 kbps | 1.9 to 2.4 MB |

A higher bitrate than the WebM had does not add quality; browser recordings of speech rarely need more than 128 kbps.

## Need the video instead?

To keep picture and sound in a format every player opens, use [WebM to MP4](https://sharelargefilesfree.com/tools/webm-to-mp4). To cut the MP3 afterwards, use [MP3 cutter](https://sharelargefilesfree.com/tools/mp3-cutter). Files are processed on your device and never uploaded.
