What Is AIFF?
AIFF (Audio Interchange File Format) is Apple's uncompressed audio format — the Mac equivalent of WAV. It stores CD-quality audio without any compression.
Why Convert to AIFF?
Mac Audio Production
AIFF is the native format for Logic Pro, GarageBand, and Final Cut Pro. Converting to AIFF ensures seamless integration with Apple's professional audio tools.
Lossless Editing
AIFF is uncompressed — editing, processing, and re-exporting won't introduce generational quality loss like working with MP3 or AAC.
Apple Ecosystem
AIFF plays natively in QuickTime, Apple Music, and all macOS/iOS audio applications.
Competitors like changemyfile.com notes "AIFF is Apple's standard for uncompressed audio" and "audio editors who work with uncompressed formats report cleaner results when applying effects." runconvert.com confirms "AIFF is the native uncompressed audio format for macOS, opening immediately in QuickTime, Apple Music, and Logic Pro." ahaconvert.com explains AIFF "keeps the original recording quality without losing any audio data."
