What is FLAC (Free Lossless Audio Codec)?

FLAC compresses audio to about half the original size without losing any quality. You can always decode it back to the exact original. Popular for music archiving and audiophile collections.

AAC sounds better than MP3 at the same bitrate and is the default audio format on Apple devices. If you listen on an iPhone, iPad, or through iTunes, your music is probably AAC.
