# Convert M4A to FLAC

Convert M4A to FLAC right in your browser — free, private, nothing is uploaded. Get a lossless file any editor opens — no further quality loss.

M4A wraps AAC audio in an MPEG-4 container — the format iTunes and Apple Music use. AAC squeezes better quality than MP3 out of the same bitrate, at the cost of slightly narrower support.

FLAC compresses audio without losing anything — a perfect, bit-for-bit copy at a fraction of the WAV size, which makes it the default choice for archiving music.

Converting M4A to FLAC is about compatibility rather than quality: some editors, DAWs and pipelines simply insist on FLAC. You get a file they open natively — but the audio can never get better than the M4A you start from.
