How to convert MP3 to WAV
- Add your MP3 files. Drag them onto the box above or click to choose them. You can add several at once.
- Check the target is WAV. It is already selected. Adjust the quality under Options if you want.
- Click Convert. The conversion runs in your browser — the file is never uploaded to a server.
- Download the WAV. When it finishes, click Download on each file.
When you need this
Importing into software or devices that reject MP3: some DJ gear, samplers, broadcast systems, older editing suites and phone systems.
MP3 vs WAV
MP3
The most widely supported audio format. Lossy compression keeps files small — about 1.4 MB per minute at 192 kbps — while sounding transparent to most listeners.
Best for: music libraries, podcasts, phones, car stereos, anything that just needs to play.
WAV
Uncompressed PCM audio. Every sample is stored as-is, so there is nothing to decode and nothing lost — at the cost of roughly 10 MB per minute of stereo.
Best for: video editors, DAWs, samplers, broadcast and any tool that wants raw audio.
Will I lose quality?
Converting MP3 to WAV does not bring back what the MP3 compression already removed: the WAV will sound exactly like the MP3, only bigger. Do it when an app or device asks for WAV, not to improve the sound. The good news is that nothing more is lost either.
