Convert FLAC to MP3.
Compress lossless FLAC into portable, high-bitrate MP3 that plays everywhere.
FLAC to MP3: lossless to plays-everywhere
FLAC is lossless — full CD or hi-res quality at roughly half the size of a WAV — which makes it the audiophile's choice for a music library. The catch is support: plenty of phones, car stereos and budget players still can't read FLAC. MP3 plays on literally everything.
The trade-off
FLAC to MP3 is a lossy step: you give up some data you mostly can't hear in exchange for universal compatibility and a smaller file. The sensible workflow is to keep your FLAC files as the master copies and generate MP3s for the devices that need them.
Will it sound good?
At a high bitrate, yes — excellent on normal gear. Listeners with high-end headphones may occasionally notice on demanding tracks, but for everyday playback a high-bitrate MP3 is hard to fault.

FLAC to MP3: re-encoded
MP3 is a compressed, lossy audio format, so this re-encodes the sound and the file gets smaller. Every lossy re-encode sheds a little quality, so convert from the best source you have rather than chaining conversions.
