MP3 is the most universally compatible audio format. It uses lossy compression to make small files that play on virtually any device, app or website. WAV is an uncompressed, lossless format that stores raw audio at full quality. Files are large, but the audio is pristine, which is why it is the standard for editing and mastering. Note that converting a compressed MP3 file to lossless WAV can’t restore detail the original MP3 compression already discarded — it gives you an uncompressed copy, handy for editing.

How to convert MP3 to WAV

  1. Add your MP3 files. Drag your MP3 audio onto the drop zone or click to browse. You can add several at once.
  2. Convert. Each track is re-encoded to WAV on your device using your browser’s native audio engine.
