What changes when you convert CAF to AIFF
Core Audio Format is a container rather than a single codec, so what it holds depends on how the file was made. It can carry PCM, ALAC, AAC, Opus, which means two files with the same extension can differ in quality and size. Check the source before assuming which one you have.
The two formats are aimed at different jobs. CAF is typically used for iOS development, the Apple ecosystem, very long recordings, 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: CAF metadata chunks in the source becomes ID3 chunk (limited) in the result. Standard fields map cleanly; niche custom tags often do not.
Moving to AIFF moves you onto an open, royalty-free format, which matters if the files need to outlive any single vendor.
