Contrary to popular belief, FLAC is not "lossless MP3". It is a compressed format that exactly reproduces the original (identical to WAV), but lighter. Ideal for a music library.
You have a FLAC music library for quality at home, but want to listen on your phone. Convert it to AAC 256 kbps: divide the weight by 3 with no audible loss.
