About FLAC Files

.flac Icon

A .flac file is an audio file saved in the Free Lossless Audio Codec (FLAC) format. The lossless format results in files that store higher-quality audio than .mp3 files but at larger file sizes (up to 5 to 6 times larger).

FLAC is an open format released in 2001 and maintained by the Xiph.Org Foundation. The format may store multiple types of audio but often saves songs ripped from CDs. Because .flac files are considerably larger than .mp3 and .aac files (limiting their transfer viability), the format never became as common as MP3 and AAC formats.

Converting FLAC Files

While .flac files store higher-quality audio than MP3 and AAC formats, you may want to convert them to .mp3 or .aac files to save space when transferring or archiving the files (especially when there is a distinct storage limitation). For example, a .flac file that is 25 MB may only be 5 MB as an .mp3 file.
