Convert AAC to OGG
Updated Jul 2026
AAC is the compressed audio format behind Apple Music, iTunes, and most iPhone recordings. OGG, or Ogg Vorbis, is what many games, apps, and open web projects expect instead. To convert, open the AAC file in a converter and export it as OGG. It can be done entirely on your own computer, with nothing uploaded anywhere.

How to convert AAC to OGG
- Open Morphjet and drag in the AAC files you want to convert, a single track or a whole folder at once.
- Choose OGG as the output format, and set a bitrate if you want to balance file size against quality.
- Convert. The OGG files are written next to your originals, and nothing leaves your machine.
AAC vs OGG: what actually changes
| AAC | OGG | |
|---|---|---|
| Opens everywhere | Yes, native on iPhone, Mac, and most phones and media apps | Limited, needs a compatible player, browser, or game engine, not native on Apple devices |
| File size | Compact at typical streaming bitrates | Similar, sometimes a touch smaller at the same quality setting |
| Quality | Good, lossy compression tuned for music | Good, lossy compression, though converting one lossy format into another loses a little more |
| Common uses | Apple Music, iTunes, streaming, iPhone voice memos | Games, open web audio, Android system sounds |
| Title and artist tags | Yes, standard audio tags | Yes, Vorbis comment tags, though not every field maps over automatically |
When to convert, and when not to
Convert AAC to OGG when a game engine, app, or platform specifically calls for Ogg Vorbis, or when you want an audio format that isn't tied to Apple's ecosystem.
Keep the AAC original if you're only going to play it in Apple Music or on an iPhone, since AAC already works there without conversion, and going from one lossy format to another loses a bit of quality you can't get back.
Why not just use an online converter?
Voice memos, podcast episodes, and home recordings often get run through an online converter just to change formats, which means the audio sits on someone else's server, at least briefly, before you get it back. Converting AAC to OGG on your own computer skips that step, so the file never has to travel anywhere.
Questions
Does converting AAC to OGG lose quality?
A little. Both are lossy formats, and re-encoding from one to the other loses slightly more than either does on its own. For games, apps, or general playback the difference is hard to notice.
Will an OGG file play on an iPhone or in iTunes?
Not natively. Apple's built-in players expect AAC or similar formats, so you'd need an app that specifically supports Ogg Vorbis to play it there.
Do the song title and artist tags carry over?
Mostly. Morphjet copies the tags from the AAC file into Vorbis comment fields on the OGG, though a few unusual or app-specific fields may not map over exactly.
Why would something need OGG instead of AAC?
Many game engines, open web audio players, and Android system sounds are built around Ogg Vorbis, so that's the format they expect, even if the source recording started as AAC.
Can I convert AAC to OGG without uploading the file?
Yes. Morphjet converts the file on your own computer, so it never travels over the internet, and it works the same with your wifi off.
