About this tool

MP3 files often come from everywhere: downloads, podcasts, phones. The problem: some editing software, CD burning and platforms require WAV. Drop your files: they're converted to WAV on your device, without being uploaded.

When to use it

Play anywhere

MP3 plays on every phone, car, speaker and app.

Make a file smaller

An MP3 is about ten times smaller than a WAV for similar listening quality.

Prepare for editing

Lossless WAV suits editing and mixing software.

How to use

  1. Drop one or more MP3 files.
  2. Choose the quality if needed.
  3. Wait for the conversion to WAV.
  4. Download the WAV files.

How it works

The file is decoded in your browser with the Mediabunny library, then re-encoded in the chosen format: MP3 with the LAME encoder, AAC and M4A with the browser's encoder or a built-in one, FLAC and WAV losslessly.

Nothing is uploaded: your files stay on your device, however many or large they are.

Tips for best results

  • 192 kbps is enough for music; 128 kbps for voice.
  • Keep the original: each conversion to a compressed format loses a little quality.
  • To cut a section, use “Cut audio”.
  • To get the sound from a video, drop the video directly.

Common problems and fixes

The file isn't read

Some rare or protected (DRM) formats can't be read: try a recent browser.

Conversion is slow

Long files take longer on a phone: use a computer if you can.

The converted file is bigger

A WAV or FLAC is bigger than an MP3: that's normal for a lossless format.

Frequently asked questions

Are my files uploaded?

No, conversion happens in your browser.

Can I convert several files?

Yes, drop them together: they're converted one after another.

Is quality preserved?

It depends on the bitrate; a lossless format doesn't restore quality already lost.

Are videos accepted?

Yes, only their sound is converted.
