Why convert AIFF to MP3

AIFF is the Mac studio's lossless format and a favourite of DJs who want tags on lossless files. Like WAV, it is large: around 10 MB per minute.

Converting AIFF to a 320 kbps MP3 gives you a sharing copy that fits in an email or chat message.

Share an AIFF bounce for quick feedback.

Send a lighter file to DJs and press.

Make a portable copy of a lossless crate.

AIFF is lossless and MP3 is lossy, so this is a one-time quality step down that is hard to hear at 320 kbps.

Keep the AIFF as your master for distribution and future conversions.
