Convert OGG to M4B
OGG is a compressed audio format often used for game sound and streaming, while M4B is the audiobook format that audiobook apps recognize, with support for chapters and remembering where you stopped. To convert, open the OGG file in a converter and export it as M4B, right on your own computer without uploading anything.

How to convert OGG to M4B

- Choose M4B as the output format.
- Convert. The M4B is written next to your original, and nothing leaves your machine.
OGG vs M4B: what actually changes
| OGG | M4B | |
|---|---|---|
| Recognized as an audiobook | No, treated as a plain audio track | Yes, opens in audiobook apps with chapters and a saved position |
| Remembers where you stopped | No | Yes |
| Chapter markers | Not supported | Supported |
| Quality | Lossy compression | Lossy compression, with a small extra loss since you're re-encoding from one lossy format to another |
| File size | Compact | Similar, sometimes slightly larger depending on settings |
| Metadata | Basic tags (title, artist, album) | Audiobook-style tags, including author, narrator, and chapter titles |
When to convert, and when not to
Convert OGG to M4B when the file is spoken content, like an audiobook, lecture, or podcast, and you want it to behave like one: chapters, a remembered playback position, and recognition in audiobook apps.
Keep the OGG if the audio is music or game sound, since M4B's audiobook behavior (like resuming playback and single-track chapter navigation) doesn't fit music, and the conversion adds a small quality loss for no real benefit.
Why not just use an online converter?
Recordings people convert to M4B are often personal, like a voice memo, a lecture, or a family reading, not just any audio file. An online converter means that recording gets uploaded to a server you don't control before you get it back. Converting on your own computer keeps it there the whole time, on wifi or off.
Questions
Does converting OGG to M4B lose quality?
A little. Both OGG and M4B are lossy formats, so re-encoding from one to the other adds a small extra loss on top of what's already in the OGG file. For spoken-word audio it's usually not noticeable.
Will the M4B remember where I stopped listening?
Yes, that's the main reason people convert to M4B. Audiobook apps use the M4B format to save your playback position automatically, which plain audio formats like OGG don't support.
Does the M4B keep chapter markers?
If the original OGG file didn't have chapter markers, the M4B won't either. What M4B adds is the ability to hold them, so if you want chapters you'll need to add them during conversion or in an editing tool afterward.
Will M4B play on Windows or Android?
Yes, most modern media players open M4B fine. The chapter and bookmark features are just most useful in apps built specifically for audiobooks and podcasts.
Can I convert OGG to M4B without uploading the file?
Yes. A desktop app like Morphjet converts the file locally, so it never travels over the internet, even for long recordings.
