What is a AIFF file?

AIFF (Audio Interchange File Format) is a lossless audio format developed by Apple in the late 1980s. It's often used on Mac systems and is comparable in structure and purpose to WAV files on Windows. AIFF files store uncompressed PCM audio, which ensures excellent sound quality.

Because of their high fidelity, AIFF files are popular in professional music production, archiving, and broadcasting. However, they can be quite large compared to compressed formats, making them less ideal for casual listening or mobile devices.

How to open AIFF files

AIFF files can be opened with media players like iTunes, VLC, Windows Media Player, and QuickTime. They’re also supported by professional audio tools such as Logic Pro and Pro Tools.

To convert large AIFF files to compressed formats like MP3, you can use AnyConv’s fast online converter.
