FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. 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 <a href="links.html#hardware">supported devices</a>) just like you would an MP3 file.<br />

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.

New metadata blocks can be defined and implemented in future versions of FLAC without breaking older streams or decoders.

Lossy. FLAC is intended for lossless compression only, as there are many good lossy formats already, such as <a href="http://www.xiph.org/ogg/vorbis/index.html">Vorbis</a>, <a href="http://www.musepack.net/">MPC</a>, and <a href="http://www.mp3-tech.org/">MP3</a> (see <a href="http://www.mp3dev.org/mp3/">LAME</a> for an excellent open-source implementation).

DRM. There is no intention to add any copy prevention methods. Of course, we can't stop someone from encrypting a FLAC stream in another container (e.g. the way Apple encrypts AAC in MP4 with FairPlay), that is the choice of the user.
