- Convert to MP3, WAV, M4R, etc., online with Zamzar or FileZigZag.
This article explains AAC files, including how to open one and how to convert one to a different audio file format.
What Is an AAC File?
A file with the AAC file extension is a MPEG-2 Advanced Audio Coding file. It's similar to the MP3 audio format but includes some performance improvements.
Apple's iTunes and iTunes Store use Advanced Audio Coding as their default encoding method for music files. It's also the standard audio format for many other devices and platforms.
AAC files can most definitely use the .AAC file extension, but they're more commonly seen wrapped in the M4A file container, and therefore usually carry that file extension.
AAC is also short for some terms that have nothing to do with this audio file format, like Acer America Corp. and advanced access control.
How to Play an AAC File
You can open an AAC file with iTunes. Use File > Add to Library on a Mac, or File > Add File to Library or Add Folder to Library in Windows.
Another way to play this audio file is with VLC, Media Player Classic (MPC-HC), Windows Media Player, MPlayer, Audials One, and likely many other multi-format media players.
If you need help opening one in the Audacity audio editing software, see their guide on how to import files from iTunes. You might need to install the FFmpeg library.
How to Convert an AAC File
If you have it installed, converting from AAC to MP3 with iTunes is easy and convenient. But that's not the only program that supports conversions, and MP3 isn't the only format you can change the AAC file to.
You can also use a dedicated free audio converter. Most of the programs from that list let you convert one to MP3, WAV, WMA, and other similar audio formats. You can also use a free audio converter to save the file as an M4R ringtone for use on an iPhone.
FileZigZag is one way you can convert AAC files online on any other operating system, because it works through a web browser. Upload the file there to be given the option to convert AAC to MP3, WMA, FLAC, WAV, RA, M4A, AIF/AIFF/AIFC, OPUS, and lots of other formats. Zamzar is very similar.
Some songs purchased through iTunes may be encoded in a particular type of protected AAC format, and therefore can't be converted with a file converter.
Still Can't Open the File?
The AAC file extension shares some of the same letters as other file extensions used by unrelated file formats. Some examples of this include AC (Autoconf Script), AAE (Sidecar Image Format), AAF, AA, AAX (Audible Enhanced Audiobook), ACC (Graphics Accounts Data), AC3, and DAA.
