# WebM to MP3

ToolSugar converts a WebM file, the format most browser and screen recorders save, into an MP3 on your own device. WebM audio is usually Opus, which many players and editors reject, so MP3 is the easy way to reuse it. Nothing is uploaded. Your first run fetches a 32 MB engine from a public CDN.

Runs on your device

## How it works

1. Choose the WebM recording.
2. Set the quality. A lower bitrate makes a smaller file.
3. Press convert to MP3.
4. Download the MP3 and open it in any player or editor.

## Key facts

- **Tested with**: WebM video with Opus audio.
- **Why convert**: Many editors and older players cannot open Opus in WebM, and nearly all can open MP3.
- **Size to expect**: 128 kbps is about 1 MB per minute.

## Common uses

- Pulling the narration from a screen recording.
- Reusing the audio of an online meeting you recorded in the browser.
- Opening a browser voice recording in an editor that rejects WebM.

## Questions

### Can a WebM with no sound be converted?

No, and the tool tells you so. Screen recorders often leave out sound unless you turned on the microphone or tab audio.

### Will it read an audio-only WebM?

The file picker accepts them and the same engine reads them, though our tests use WebM video with Opus sound.
