How to Open, Edit, and Convert AIFF, AIF and AIFC Files

AIFF Files
AIFF Files.

Files that end in the .AIF or .AIFF file extension are Audio Interchange File Format files. This format was developed by Apple in 1988 and is based on the Interchange file format (.IFF).

Unlike the common MP3 audio format, AIFF and AIF files are uncompressed. This means that, while they retain a higher quality sound than MP3, they do take up significantly more disk space - generally 10 MB for every minute of audio.

Windows software typically append the .AIF file extension to these files, while macOS users are more likely to see .AIFF files.

One common variant of the AIFF format that does utilize compression, and therefore uses less disk space, is called AIFF-C or AIFC, which stands for Compressed Audio Interchange File Format. Files in these formats typically use the .AIFC extension.

How to Open AIFF & AIF Files

You can play AIFF & AIF files with Windows Media Player, Apple iTunes, Apple QuickTime, VLC, and probably most other multi-format media players. Mac computers can open AIFF and AIF files with those Apple programs too, as well as with Roxio Toast.

Apple devices like the iPhone and iPad should be able to play AIFF/AIF files natively without an app. A file converter (more on these below) may be needed if you can't play one of these files on an Android or other non-Apple mobile device.

Note: If these programs aren't opening your file, check that you're reading the file extension correctly and that you aren't confusing an AIT, AIR, or AFI file with an AIFF or AIF file.

How to Convert AIF & AIFF Files

If you already have iTunes on your computer, you can use it to convert an AIFF and AIF files to other formats like MP3. See our How to Convert iTunes Songs to MP3 guide for details on this process.

You can also convert AIFF/AIF to WAV, FLAC, AAC, AC3, M4A, M4R, WMA, RA, and other formats using a free file converter. DVDVideoSoft's Free Studio is a great free audio converter, but if your AIFF file is relatively small, you can probably get away with an online converter like FileZigZag or Zamzar.

How to Open & Convert AIFC Files

Files that utilize the compressed version of Audio Interchange File Format probably have the .AIFC file extension. They have CD-like audio quality and are similar to WAV files, except that they use compression (like ULAW, ALAW, or G722) to lower the overall size of the file.

Like AIFF and AIF files, AIFC files can open with Apple's iTunes and QuickTime software, as well as with Windows Media Player, VLC, Adobe Audition, vgmstream, and likely some other media players.

See this list of free audio converter programs if you need to convert an AIFC file to a different audio format like MP3, WAV, AIFF, WMA, M4A, etc. Many of those converters require that you download the program to your computer in order to save the AIFC file to a new format. However, just like with the uncompressed Audio Interchange File Format we talk about above, AIFC files can also be converted online with FileZigZag and Zamzar.

Note: AIFC also stands for Australian Institute of Family Counseling. If that's what you're looking for, and not the audio file format, you can visit the website for more information.
