What is AAC?
AAC is the successor to MP3: better quality at the same bitrate, and the default for Apple, YouTube and most streaming.
What is AIFF?
AIFF is an audio format. Converting it trades off file size, quality and compatibility to fit where the sound will be played.
Why convert AAC to AIFF?
Most people convert AAC to AIFF for compatibility — a website, app or device insists on AIFF, and AAC simply won't open. AIFF is widely supported, which makes it a dependable target. Audio is processed with ffmpeg using high-quality encoders (LAME, libopus, libvorbis, FLAC and more), so you get the best possible result for the destination format.
AAC vs AIFF: what changes
Going from the lossy AAC to the lossless AIFF won't recover detail AAC already discarded, but it gives you a clean, re-editable copy that won't degrade further when you edit and re-save it.
