Convert MP3 to WAV online, free
To convert MP3 to WAV, drop the MP3 on the box above, keep WAV selected and click “Convert”. You get an uncompressed 16-bit PCM WAV with the same sample rate and channels as the MP3. It is made in your browser; nothing is uploaded.
Why convert MP3 to WAV?
- Audio editors and DAWs that work best with WAV
- Samplers, drum machines and DJ gear that only load WAV
- Apps, phone systems and game engines that ask for WAV files
- Editing without encoding to MP3 again after every save
Will the WAV sound better?
No. MP3 is lossy: what it dropped when it was made cannot come back. The WAV keeps exactly the sound the MP3 had, no better and no worse. What WAV gives you is that further editing and saving loses nothing more.
How big will the WAV be?
About 10.6 MB per minute for CD-quality stereo (44.1 kHz, 16-bit), roughly ten times the MP3. A 4-minute song becomes about 42 MB.
