# Convert M4A to OGG

Convert M4A to OGG right in your browser — free, private, nothing is uploaded. One-click re-encode for compatibility.

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.

OGG (Vorbis) is a free, open lossy format with very good quality per byte — a favourite in games, open-source software and projects that want to avoid patent-encumbered codecs.

Converting M4A to OGG is a compatibility move: both formats are lossy, so the goal isn't quality — it's producing a file that fits games, open-source pipelines and the web. Expect the sound to stay essentially the same, with a small second round of encoding loss.
