Why convert OGG to M4A?
Apple's ecosystem - iPhone, iPad, Apple Music, and older iPods - does not support Ogg Vorbis and will not play .ogg files natively. .M4A is Apple's preferred audio format and works on every current Apple device without extra apps. Game players often extract .ogg audio tracks and need .m4a for use in iMovie or Apple video projects.

Open .M4A details →Quality & what to watch
- Both OGG and M4A are lossy formats - re-encoding always adds a second generation of quality loss; the M4A will not sound better than the OGG source.
- OGG game files often carry loop-point tags (
LOOPSTART/LOOPEND) for seamless looping; M4A has no equivalent, so the loop metadata is lost on conversion. - Common metadata fields (artist, album, title) are remapped correctly by most tools, but custom or uncommon Vorbis comment tags may be dropped.
