The Free Lossless Audio Codec is a digital audio format that allows for some compression, but it preserves all the information present in the original recording. FLAC files are similar to MP3s, but they are necessarily larger and can offer higher quality. Unfortunately, FLAC is not as widely supported as the MP3 format so you may find it necessary to convert FLAC files for use with some devices and programs. There are, however, many free programs available online that do just that. Some are simple to use; others boast extra features.
