Converting MP3 to WAV makes the audio easier to use in editors that expect uncompressed PCM. It does not restore detail that was removed when the MP3 was originally encoded. It just stores the same audio data without further compression.

FAQ

Is my file uploaded anywhere?
No. Conversion happens entirely in your browser. Your audio never leaves your device.
Why is the WAV file bigger than the MP3?
WAV is uncompressed audio, so it's expected to be significantly larger than MP3, often 5-10x, depending on the original MP3 bitrate.
Does converting to WAV restore audio quality lost in the MP3?
No. MP3 is a lossy format. Detail removed during the original MP3 encoding is gone and can't be recovered. Converting to WAV just stores the MP3's existing audio data uncompressed; it doesn't add anything back.
Why convert to WAV at all, then?
Some audio editors and older software expect uncompressed PCM audio rather than a compressed format, or handle WAV more reliably for further processing.
