How to convert OGG to M4A
- Add your .OGG file - drop it in the box above or click to browse.
- Convert it to .M4A in a few seconds.
- Download your new .M4A file.
What to expect
- 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.
Frequently asked questions
Will the M4A sound worse than the OGG?
Yes, slightly. Re-encoding from one lossy format to another always adds a generation of quality loss. The difference is small at 192 kbit/s or above, but it is unavoidable.
Why does Apple Music not play OGG files?
Apple's built-in media apps only support codecs included in Apple's audio frameworks, and Ogg Vorbis is not among them. M4A/AAC is Apple's native format and plays on every current Apple device.
What bitrate should I choose for the M4A?
For music, 192 kbit/s is a safe default; 256 kbit/s if storage is not a concern. For speech or podcasts, 96 kbit/s is enough. Do not go lower than the source OGG bitrate.
Can I convert OGG to M4A without losing quality?
No. Both formats are lossy, so some audio data is always lost in re-encoding. If you have a lossless source (WAV or FLAC), encode from that instead.
