Why convert MP3 to WAV?
WAV is uncompressed, so further editing and re-saving won't reduce quality any more. (It can't restore detail that MP3 compression already removed.)
WAV is best for audio editing, DAWs, mastering, broadcast and archiving. Supported by every audio editor, DAW and operating system.
Will I lose quality?
Converting MP3 to WAV keeps all the quality that is in your MP3 file - nothing more is lost. However, it cannot recover detail removed when the MP3 was originally created, and the WAV file will be larger.

What is the difference between MP3 and WAV?
MP3 (MPEG-1 Audio Layer III) is a compressed (lossy) format, the most widely supported compressed audio format. MP3 removes sounds the ear is unlikely to notice to make files about 10x smaller than CD audio. WAV (Waveform Audio File Format) is a uncompressed format: uncompressed PCM audio with perfect quality. WAV files are large but every sample is preserved exactly, making them the standard for recording and editing.
Does it work on Mac, Windows, iPhone and Android?
