Converting FLAC to MP3 the right way

FLAC is lossless: it keeps every detail of the original recording, but a song takes 20–60 MB. MP3 at 320 kbps is about a quarter of that and, for most listeners and most equipment, indistinguishable.

High-resolution FLAC files (24-bit, 88.2–192 kHz) are converted with a high-quality resampler to the highest sample rate MP3 supports (48 kHz) unless you choose another rate.

Keep your FLAC files as the master copy — you can always create new MP3s from them, but not the other way round.
