If you use Windows, you can get a free version of dBpoweramp, which can convert files, and a paid version, which you can use to rip CDs, edit tags and more. (You can always convert them back to FLAC later if you want, with no loss in quality.) It’s quick and easy to use, and you can either keep your original FLAC files, or delete them after conversion and just keep the ALAC files. It can convert too and from just about every audio format you will even want to use, and does so retaining metadata tags with track info and album artwork. The best app for doing this on a Mac is the free XLD. (The same is true with other uncompressed or lossless formats, such as WAV, AIFF, APE, SHN, and others.) Converting audio files from one lossless format to another is lossless in other words, there is no quality lost when you convert from FLAC to ALAC. While iTunes doesn’t support FLAC files, it’s very easy to convert them to Apple Lossless, or ALAC, an equivalent lossless format that iTunes does support. You may want to play these files in iTunes. FLAC files are losslessly compressed, which means that, when you play them back, they are bit-perfect replicas of the original uncompressed files (on a CD or high-resolution files). If you buy or download music in FLAC files, you do so because you want the best quality audio files.
