Convert OGG to AAC
Updated Jul 2026
OGG is a compressed audio format common in games and some non-Apple apps, while AAC is the format Apple devices and most streaming services expect. To convert OGG to AAC, open the file in a converter and export it as AAC. Doing this on your own computer means the audio never has to leave your machine.

How to convert OGG to AAC
- Open Morphjet and drag in the OGG files you want to convert. Add a single track or a whole folder of them at once.
- Choose AAC as the output format, and pick a bitrate if you want to balance size against quality.
- Convert. The AAC files are written next to your originals, and nothing leaves your machine.
OGG vs AAC: what actually changes
| OGG | AAC | |
|---|---|---|
| Opens everywhere | Limited, mostly games and non-Apple apps | Yes, native on Apple devices and most streaming apps |
| File size | Compact | Similar, sometimes slightly smaller at the same quality setting |
| Quality | Good, lossy compression | Good, lossy compression, generally considered slightly more efficient than OGG at low bitrates |
| Common use | Video games, some Android and Linux apps | iTunes, Apple Music, most streaming services |
| Metadata (tags) | Yes, stores title and artist tags | Yes, stores title and artist tags |
When to convert, and when not to
Convert OGG to AAC when you want to play the audio on an iPhone or Mac, add it to a library that expects AAC, or share it with someone whose player doesn't support OGG.
Keep the OGG original if it's already working fine in whatever game, app, or device you're using, since converting a lossy format to another lossy format doesn't add quality, only compatibility.
Why not just use an online converter?
Converting audio through a website usually means uploading the file to a server you know nothing about, waiting in a queue, and hoping it gets deleted afterward. Morphjet converts OGG to AAC right on your own computer, so the file, and whatever it contains, never gets sent anywhere.
Questions
Does converting OGG to AAC lose quality?
Both are lossy formats, so re-encoding from OGG to AAC involves a small additional quality loss on top of whatever compression the OGG already has. In practice it's hard to hear on typical speakers or headphones, but it's not a perfect copy.
Will the AAC file keep the title and artist tags?
Yes. Metadata like title, artist, and album carries over from OGG to AAC during conversion, since both formats support tagging.
Why doesn't my iPhone or Mac play OGG files?
OGG never became a default format on Apple devices, which favor AAC instead. Converting to AAC is the simplest way to get the audio playing without extra apps.
Can I convert OGG to AAC without uploading the file anywhere?
Yes. A desktop app like Morphjet does the conversion on your own computer, so the audio file stays local the whole time, even with your wifi off.
What bitrate should I choose for AAC?
For most music, a mid to high bitrate keeps the sound close to the original. If the source OGG was already low bitrate, choosing a higher one for the AAC won't add back detail that isn't there.
