About AIFF
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format. It stores raw PCM audio data — the same data as WAV, but in an Apple-native container. AIFF files are lossless and used natively by Logic Pro, GarageBand, and Pro Tools on macOS.
About MP3
MP3 (MPEG Audio Layer III) is the most universally supported audio format. It uses lossy compression to produce small files without dramatically sacrificing perceived audio quality. MP3 plays on every device, operating system, car stereo, and media player.
Why Convert AIFF to MP3?
AIFF files are large — a 3-minute track can easily be 30–50 MB of raw audio data. Converting to MP3 compresses that down to 3–7 MB while maintaining good perceived quality, making files easy to share, stream, or store on mobile devices. AIFF is an ideal production format but a poor distribution format; MP3 solves that. This conversion is common for musicians, podcasters, and anyone working in Apple's audio ecosystem who needs files that play anywhere.
