Why Convert AIFF to MP3?

80% Smaller Files

AIFF is uncompressed — about 10MB per minute of audio. A 4-minute song is ~40MB as AIFF but only ~8MB as 320kbps MP3. An 80% reduction that makes sharing and mobile storage practical.

Universal Playback

AIFF is primarily a Mac format (Apple's equivalent of WAV). MP3 plays on every device ever made — phones, car stereos, MP3 players, Windows PCs, and all platforms.

Share GarageBand and Logic Pro Exports

GarageBand and Logic Pro can export as AIFF. Converting to MP3 makes your music shareable via email, messaging apps, and social media without requiring recipients to have Mac audio software.
