Going from WMA to AIFF locks in the quality you have now, it does not recover what was lost when the file was first encoded. That is still the right move before editing, because AIFF will not add a second round of compression damage. Budget for the size jump: about 1 MB per minute becomes roughly 21 MB per minute.
This conversion buys reach. Unlike WMA, AIFF is natively supported on macOS and iOS, which is usually the reason people convert in this direction.
This conversion moves the file toward a different purpose: WMA suits Windows media libraries, legacy archives, whereas AIFF is chosen for studio editing, the Apple ecosystem, mastering.
Tags do not transfer verbatim. WMA stores them as ASF / WM tags while AIFF uses ID3 chunk (limited), so titles and artwork are remapped and unusual custom fields may not survive.
AIFF is a royalty-free open format, so the result is not tied to one vendor and can be handled by open-source tooling without licensing questions.
Converting WMA to AIFF means moving audio out of the ASF container, introduced in 1999, and into IFF / AIFF, which arrived in 1988. The two were designed with different priorities, and that is what determines whether this conversion costs you quality, storage, or compatibility.
Developed by Microsoft in 1999, WMA carries lossy-compressed audio (WMA or WMA Pro). That sets the upper bound on what any conversion can preserve.
AIFF was introduced by Apple in 1988. It holds uncompressed audio (PCM) and plays natively on macOS and iOS.
