Converting MP3 to WAV
MP3 is lossy and compressed; WAV is uncompressed. Converting MP3 to WAV is useful when editing software, a kiosk or a CD burner requires uncompressed audio.
An honest note: converting MP3 to WAV does not “restore” the quality lost during compression — it produces a WAV-compatible file from the existing audio.
Everything happens in your browser: no file is sent to a server.
MP3 vs WAV: what's the difference?
| Criterion | MP3 | WAV |
|---|---|---|
| Compression | Lossy | None — raw audio |
| File size | Light | Around 10× heavier |
| Repeated exports | Degrades each save | No loss, even after several passes |
| Burning an audio CD | Needs conversion | Native format |
Important: converting an MP3 to WAV won't restore lost quality — the WAV is simply an uncompressed copy of the MP3. The point is to edit it without further degradation, not to "recover" audio.
When should you convert MP3 to WAV?
- Import the track into editing or music-production software.
- Burn an audio CD playable on a hi-fi deck.
- Work the audio in several steps without cumulative loss.
- Use the sound in a tool that requires uncompressed WAV.
