Apple Computer developed the AIFF format in 1998, basing it on Electronic Arts' .IFF format. Standard AIF files use a sampling rate of 44.1KHz, are 16-bit, and have two channels for stereo sound.

AIF files are similar to .MP3 files but they are saved in an uncompressed format, whereas MP3 files are compressed. This difference results in AIF files being larger in size but they also store higher-quality audio.

NOTE: AIF files may also be saved as .AIFF files.

How do I open a AIF file?

You can open AIF files with various media players, such as Microsoft Windows Media Player (Windows), Apple QuickTime Player (Mac), Apple Music (macOS), and VideoLAN VLC media player (multiplatform).

How do I convert AIF files?

You can convert AIF files with various applications, including the Adobe Audition (Windows, Mac) and Audacity (cross-platform) digital audio workstations (DAW). You can use these DAWs to convert AIF files to different audio formats, such as MP3 or WAV.

For example, you can convert an AIF file to an MP3 file in Audacity by selecting File → Export → Export as MP3.
