Why Convert AIFF to MP3?
AIFF is Apple's uncompressed audio format. Files are massive. A 4-minute song takes 40MB+ in AIFF. Converting to MP3 at 320kbps drops that to 7-8MB with excellent quality. If you're sharing music, building a portable library, or uploading to the web, MP3 is the practical choice.

About 80% smaller. A 40MB AIFF file becomes roughly 7-8MB as a 320kbps MP3.
Should I use AIFF or WAV for production?
Either works. AIFF has slightly better metadata support on Mac. WAV is more universal. Both are uncompressed with identical audio quality.
Is AIFF the same as Apple Lossless (ALAC)?
No. AIFF is uncompressed (like WAV). ALAC is lossless compressed (like FLAC). ALAC files are smaller but both preserve full quality.
