FLAC File Type


FLAC, acronym for Free Lossless Audio Codec, is a compressed audio format that allows uncompressed audio quality to be reduced without introducing any information loss. FLAC is a compressed audio format that can reduce the size of uncompressed audio files and preserve the same high level of sound quality. It uses lossless compression which means it does not remove any part of the data from your original sound file, so you can never lose data in your original file. FLAC was designed by Josh Coalson to be an open source and unpatented alternative to other popular compressed formats such as MP3. FLAC has become one of the most popular formats for music distribution among audiophiles and those wishing to archive old recordings or create digital copies of their albums for personal use.
