What changes when you convert MP3 to WAV
MP3 is already lossy, so converting to WAV cannot restore detail that the original encoder discarded. What you gain is a format that survives further editing without stacking up more loss. Expect the file to grow from roughly 1.7 MB per minute to about 21 MB per minute, around 13 times larger.
The two formats are aimed at different jobs. MP3 is typically used for music libraries, podcasts, sharing with anyone, while WAV is the usual pick for studio editing, mastering, sample libraries. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: ID3v2 in the source becomes RIFF INFO (limited) in the result. Standard fields map cleanly; niche custom tags often do not.
About MP3 to WAV Conversion
This page converts MP3 files, stored in the MPEG-1/2 Audio Layer III container since 1993, into WAV, which uses RIFF WAVE and dates from 1991. The differences between the two containers decide what changes in the result.
MP3 comes from Fraunhofer IIS / MPEG and dates to 1993. It carries MP3, which is what determines the quality ceiling of anything you convert out of it.
WAV was introduced by Microsoft / IBM in 1991. It carries PCM and has native playback on 5 of six platform categories, which is the practical reason to choose it as a target.
