No, converting M4A to FLAC does not cause additional quality loss — FLAC uses lossless compression. However, any artifacts already present in the original M4A file will persist in the FLAC output.
FLAC files are typically 2-5x larger than equivalent M4A files because FLAC preserves all pixel data. This is expected and necessary for lossless quality.
