Convert MP3 to WAV
Convert MP3 to WAV on your device. Choose your file, convert, and check the result before sharing.
Drop the mp3 file
Drag your MP3 onto the page or click to browse. It is read locally, never sent anywhere.
Choose WAV
WAV output is 16-bit PCM, so there is no quality or bitrate menu. Click Convert to WAV to start.
Save the wav
The finished WAV downloads straight back to your device. Nothing touched a server on the way.
Why convert here, not there
No upload, ever
Audio files are personal. MP3 to WAV here happens inside one browser tab, end to end.
Local conversion
Choose your file, then click Convert to WAV. The browser may need to download the converter engine first; conversion time depends on your device and file.
No account, no daily cap
No account or daily conversion quota. The per-file hard cap is 2 GB, and available browser memory can impose a much lower practical limit.
The two formats, briefly
| MP3 | MP3 is a lossy audio format. This converter encodes it at the selected bitrate rather than copying the original audio stream. | |
|---|---|---|
| WAV | WAV is a container commonly used for PCM audio. This converter writes 16-bit PCM; the source sample rate and channels are not deliberately changed. | |
When you need this
- Decode MP3 for an editor or workflow that asks for WAV PCM audio. This output is 16-bit, not an enhancement of the original recording, and can be much larger than compressed audio.
MP3 vs WAV: what changes
| MP3 | WAV | |
|---|---|---|
| Kind | Audio | Audio |
| Compression | Lossy audio | 16-bit PCM output here |
| Typical size | Depends on the file and encoding settings. | Measure the exported file; it may be larger. |
| Opens on | Check the source in your app and browser. | Check the downloaded file in the receiving app. |
| Best for | Keep the original as your source. | WAV workflows, subject to the limits below. |
Keep the original. Compare the exported file before sharing or replacing it.
Good to know
- WAV output here is 16-bit PCM. There is no bitrate choice; converting a higher-bit-depth source can reduce precision.
- First use downloads the audio/video engine (about 30 MB). The input cap is 2 GB, but available browser memory can run out below that.
