How to convert FLAC to ALAC with FileFlip
Select the FLAC files
In Finder or on the Desktop. One file, or a whole folder with ⌘ A.
Press ⌥ F
FileFlip opens next to the selection and lists the formats it can make from FLAC. Type “ALAC” to jump to it.
Choose ALAC and press Return
The ALAC files appear next to the originals with the same names. The FLAC files stay as they are.
FLAC and ALAC
Apple’s own apps prefer ALAC for lossless music. ALAC is lossless and plays natively in Apple’s Music app and on iPhone.
What changes when you convert
- Both formats are lossless, so the sound itself doesn’t change. Only file size and compatibility do.
- ALAC files use the .m4a extension, just like AAC files.
