# WAV to MP3

ToolSugar converts WAV audio to MP3 in your browser. CD-quality stereo WAV uses about 10.6 MB per minute, while a 192 kbps MP3 uses about 1.4 MB, roughly 85 percent less. WAV has no compression to undo, so MP3 is a one-way step: keep your WAV master. Nothing is uploaded. The first run fetches a 32 MB engine.

Runs on your device

## How it works

1. Choose the WAV file from your recorder or editor.
2. Select a bitrate, 192 kbps for music or 128 kbps for speech.
3. Press convert to MP3.
4. Download the MP3 and keep the WAV as your master copy.

## Key facts

- **Size saving**: About 85 percent at 192 kbps for CD-quality stereo WAV.
- **Quality**: MP3 discards detail for good, so it cannot be turned back into the original.
- **Length**: The MP3 keeps the running time of the WAV, within 0.2 seconds in our tests.

## Common uses

- Emailing a recording that is too large as a WAV.
- Publishing a podcast episode exported from an editor.
- Loading demos from a recorder onto a phone.

## Questions

### Which bitrate is closest to WAV?

320 kbps, the highest setting here. No MP3 is identical to the WAV, so keep the WAV for a master you will edit again.

### Can I go back from MP3 to WAV?

You can make a WAV from an MP3, but the lost detail stays lost.
