How to convert MP3 to WAV

  1. 1Drop one or more MP3 files into the box above.
  2. 2WAV is already selected.
  3. 3Select Convert and download the WAV files.

What you get

  • One 16-bit WAV per MP3, at the MP3's own sample rate.
  • The WAV is about ten times the size of the MP3. It sounds the same: converting can't bring back detail the MP3 left out.
  • Up to 3 files at a time free, or 30 with Pro.

Limits

  • Free, with or without an account: files up to 500 MB, 3 at a time.
  • With Pro: files up to 2 GB, 30 at a time.
  • Big files are read from your disk as they're processed, so they don't need to fit in memory, but a phone takes longer than a computer.

What happens to your file

Your file never leaves your device. The conversion runs in your browser using code from our site, and we don't receive the file, its name or anything inside it. How we handle files.

MP3 to WAV: common questions

Is this MP3 to WAV converter free?
Yes. Files up to 500 MB convert free, without an account and without a watermark. Pro raises the limit to 2 GB a file and converts up to 30 files at a time.
Does converting MP3 to WAV improve quality?
No. It changes the container, not the sound. Use it when software needs WAV, not to make an MP3 sound better.
Is my audio uploaded?
No. The conversion runs in your browser, so the audio stays on your device and never reaches our server. Once the page has loaded it keeps working if your connection drops.
Why does the first conversion take a few seconds to start?
The converter is a copy of FFmpeg that runs in your browser. It's about 31 MB, so it downloads the first time you use it and your browser keeps it for next time.
