What changes when you convert FLAC to M4A
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.
If your source runs above 96 kHz, it will be resampled: M4A cannot store the 192 kHz that FLAC allows.
The two formats are aimed at different jobs. FLAC is typically used for long-term archiving, audiophile listening, CD ripping, while M4A is the usual pick for the Apple ecosystem, music libraries, audiobooks. That difference in intent is what most of the specification gaps above come from.
Expect metadata to be rewritten rather than copied: Vorbis comments in the source becomes MPEG-4 iTunes-style atoms in the result. Standard fields map cleanly; niche custom tags often do not.
