The very fact is that a good, simple app should convert audio files from FLAC to MP3 on Mac painlessly and without too much effort. Let me say this up front: Chances are pretty good the FLAC MP3 converter you applied for the conversion isn't on this list.
Well, it's time to crown the best of the best FLAC to MP3 converters for Mac as well as Windows. Why? Even though FLAC (Free Lossless Audio Codec) offers CD-or-better-quality music and becomes more popular, it's still not so common to play on the default music player installed on the smartphone (Updated: iPhone or iPad with iOS 11 or above can play FLAC files natively.) On the other hand, if you're not an audiophile and do not care about the sound quality, 320kbps MP3 is a good option for its incredible convenience and smaller file size.
