what is FLAC?

FLAC stands for Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to MP3, but lossless, meaning that audio is compressed in FLAC without throwing away any information. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see links to the right for supported devices) just like you would an MP3 file.

FLAC is freely available and supported on most operating systems, including Windows, "unix" (Linux, *BSD, Solaris, OS X, IRIX), BeOS, OS/2, and Amiga. There are build systems for autotools, MSVC, Watcom C, and Project Builder.

See the features page for a complete list of features, or the comparison page to see how FLAC compares with other lossless codecs.

The FLAC project consists of:

  • the stream format
  • reference encoders and decoders in library form
  • flac, a command-line program to encode and decode FLAC files
  • metaflac, a command-line metadata editor for FLAC files
  • input plugins for various music players

When we say that FLAC is "Free" it means more than just that it is available at no cost. It means that the specification of the format is fully open to the public to be used for any purpose (the FLAC project reserves the right to set the FLAC specification and certify compliance), and that neither the FLAC format nor any of the implemented encoding/decoding methods are covered by any known patent. It also means that all the source code is available under open-source licenses. It is the first truly open and free lossless audio format.


Visit the download page for links to the source code or pre-built binaries.


The documentation is available online as well as in the distributions. The general installation and usage documentation for flac and the plugins is here. For a detailed description of the FLAC format and reference encoder see the FLAC format page.
