# Convert OGG to M4A

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

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.

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.

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