What changes when you convert AIFF to CAF
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. AIFF is typically used for studio editing, the Apple ecosystem, mastering, while CAF is the usual pick for iOS development, the Apple ecosystem, very long recordings. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: ID3 chunk (limited) in the source becomes CAF metadata chunks in the result. Standard fields map cleanly; niche custom tags often do not.
CAF is a proprietary format. It works well inside its own ecosystem but is less portable than the open format you are starting from.
