Why convert
Why convert WAV to MP3?
WAV files are uncompressed and large. Converting to MP3 shrinks them dramatically — often to a tenth of the size — while staying playable on virtually any device, which makes them far easier to store, share, and sync.
- Shrink big recordings to fit more on a phone or player.
- Make studio WAV exports easy to email or upload.
- Batch-convert a folder of recordings in one pass.
- Standardise a mixed library on the most compatible format.
