Going from WebM Audio 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 1.2 MB per minute becomes roughly 21 MB per minute.
This conversion buys reach. AIFF is natively supported on 2 additional platforms compared with WebM Audio, which is usually the reason people convert in this direction.
This conversion moves the file toward a different purpose: WebM Audio suits web delivery, HTML5 video, open-source projects, whereas AIFF is chosen for studio editing, the Apple ecosystem, mastering.
Tags do not transfer verbatim. WebM Audio stores them as Matroska tags while AIFF uses ID3 chunk (limited), so titles and artwork are remapped and unusual custom fields may not survive.
Converting WebM Audio to AIFF means moving audio out of the WebM (audio-only) container, introduced in 2010, 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 Google in 2010, WebM Audio stores audio using Opus, Vorbis. That codec choice sets the upper bound on what any conversion can preserve.
AIFF, from Apple and dating to 1988, uses PCM and plays natively on 2 of the six platform categories we track. That combination is usually why people convert into it.
