Why Convert AIFF to MP3?
AIFF is Apple's uncompressed lossless format (like WAV) — pristine but huge, around 10 MB per minute. Converting to MP3 shrinks it to a fraction of the size for phones, sharing, and everyday listening. Since AIFF is lossless, the MP3 gets the best possible source; at 320 kbps it's transparent for almost all listeners. Keep the AIFF if you need a master.
Frequently Asked Questions
How do I convert AIFF to MP3?

Will the MP3 sound as good as the AIFF?
At 320kbps, MP3 is transparent for almost all listeners — very close to the AIFF at a fraction of the size. MP3 is lossy, so it isn't a bit-perfect copy.
Why is AIFF so much bigger than MP3?
AIFF is uncompressed (about 10 MB per minute), while MP3 compresses audio to roughly a tenth of that.
Is the AIFF to MP3 converter free?
Yes — it's completely free, with no account, no watermarks, and no limit on how many files you convert.
