Why Convert M4A to FLAC file?

M4A is a compressed audio format common on Apple devices, while FLAC is a lossless format that preserves full quality. Converting M4A to FLAC wraps your audio in the lossless FLAC container, useful when a system or workflow specifically expects FLAC, or when you want to keep your library in a consistent lossless format going forward.

It is worth being clear that converting M4A to FLAC does not restore quality that compression already removed — the audio simply stops losing any further quality and is stored losslessly from here on. FLAC files are much larger than M4A. This conversion is best when you need FLAC for compatibility or a uniform library, rather than as a way to improve audio that is already compressed.
