- Saves as
This MP3 to WAV converter saves an MP3 song or recording as a WAV, for editors, DJ software and CD burning programs that ask for WAV. The WAV is 16-bit and keeps the MP3's sample rate and its mono or stereo sound, so a 44.1 kHz stereo MP3, as most songs are, becomes a WAV ready for an audio CD. It's uncompressed, so it comes out several times bigger than the MP3. Your file never leaves your device. For other formats, use the audio converter.
Questions
Is the MP3 to WAV converter free?
Yes, with no sign-up and no watermark.
Does it work on my phone?
Yes, in Chrome on Android and Safari on iPhone: pick the MP3 from your phone and save the WAV. If your browser can't play a file's sound, the page says so as soon as you pick it.
Will the quality drop?
No, and it won't get better either. The WAV holds the MP3's sound as it plays, uncompressed, but WAV can't add back the detail the MP3 dropped when it was made. What changes is the size.
Is there a size limit?
No limit is set, but WAV files are big: a minute of stereo sound takes about 10 to 11 MB, so an hour comes to over 600 MB. One WAV file holds a little over six hours of stereo sound at most, so cut a longer MP3 into parts with the audio cutter first. On a phone, very long recordings can be more than the browser can handle, so use a computer for those.
