Converting to AIFF won't restore lost quality
Your WMA file has already undergone lossy compression. Converting to AIFF preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your WMA file may contain ASF metadata, DRM tags metadata. AIFF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
