What changes when you convert M4A to FLAC
MPEG-4 Part 14 is a container rather than a single codec, so what it holds depends on how the file was made. It can carry AAC-LC, HE-AAC, ALAC, which means two files with the same extension can differ in quality and size. Check the source before assuming which one you have.
The two formats are aimed at different jobs. M4A is typically used for the Apple ecosystem, music libraries, audiobooks, while FLAC is the usual pick for long-term archiving, audiophile listening, CD ripping. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: MPEG-4 iTunes-style atoms in the source becomes Vorbis comments in the result. Standard fields map cleanly; niche custom tags often do not.
