Why convert WAV to MP3
A WAV master is perfect for distribution, but it is big. A three-minute track is around 30 MB, which is too heavy for email, chat apps and many promo tools.
Converting to a 320 kbps MP3 cuts the file to roughly a quarter of the size while keeping quality that most listeners can't tell apart from the master.
Promo and demo sends
Email or message a track without a file-size bounce.
Previews for clients
Share mixes for feedback before delivering the WAV.
Social and web
Many platforms and players expect MP3.
WAV to MP3: what you keep and what you lose
WAV is uncompressed and MP3 is lossy, so some data is removed for good. Keep your WAV as the master and treat the MP3 as a sharing copy.
Send the WAV, not the MP3, to distributors and mastering engineers.
