What changes when you convert MP3 to AIFF
MP3 is already lossy, so converting to AIFF 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.
Be aware that you are narrowing playback: MP3 is natively supported on 4 platforms where AIFF is not. Convert this way when you need the format specifically, not for portability.
The two formats are aimed at different jobs. MP3 is typically used for music libraries, podcasts, sharing with anyone, while AIFF is the usual pick for studio editing, the Apple ecosystem, mastering. 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 ID3 chunk (limited) in the result. Standard fields map cleanly; niche custom tags often do not.
About MP3 to AIFF Conversion
This page converts MP3 files, stored in the MPEG-1/2 Audio Layer III container since 1993, into AIFF, which uses IFF / AIFF and dates from 1988. 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.
AIFF was introduced by Apple in 1988. It carries PCM and has native playback on 2 of six platform categories, which is the practical reason to choose it as a target.
