Convert OGG to M4A
Updated Jul 2026
OGG is a compressed audio format popular with games and free media players, while M4A is what iTunes, Apple Music, and voice memos on Mac and iPhone expect. To convert OGG to M4A, open the file in a converter and export it as M4A. Doing this on your own computer keeps the audio off other people's servers.

How to convert OGG to M4A
- Open Morphjet and drag in the OGG files you want to convert. Add one file or a whole folder at once.
- Choose M4A as the output format, and pick a bitrate if you want to control the file size.
- Convert. The M4A files are written next to your originals, and nothing leaves your machine.
OGG vs M4A: what actually changes
| OGG | M4A | |
|---|---|---|
| Opens in iTunes and on iPhone | No, needs a separate player or plugin | Yes, native format |
| File size | Compact, efficient compression | About the same size at a matching bitrate |
| Quality | Lossy, good at moderate bitrates | Lossy, with a small extra loss from re-encoding |
| Metadata (tags) | Uses its own comment-based tags | Uses iTunes-style tags, so most info carries over |
| Common uses | Games, community software, internet radio | iTunes, Apple Music, voice memos |
When to convert, and when not to
Convert OGG to M4A when you want to play the audio in iTunes or Apple Music, sync it to an iPhone, or use it somewhere that expects Apple's own audio format.
Keep the OGG original if you're staying inside software that already plays OGG natively, since converting between two lossy formats loses a little quality you can't get back.
Why not just use an online converter?
Voice memos and personal recordings saved as OGG often hold things you'd rather not hand to a stranger's server, a voice, a conversation, a private note to yourself. Run the file through an online converter and a copy of it sits on someone else's machine while it works. Convert it on your own computer instead, and the audio never leaves your hard drive.
Questions
Does converting OGG to M4A lose quality?
A little. Both formats are lossy, so going from OGG to M4A means compressing already-compressed audio, which adds a small amount of extra loss. It's usually not noticeable for casual listening, but it does add up if you convert back and forth repeatedly.
Will M4A keep the song or track info?
Mostly. OGG stores tags like title and artist in its own format, and M4A uses the tagging system iTunes expects, so basic info usually transfers, though occasionally a field doesn't map over and needs to be re-entered.
Why won't OGG files play on my iPhone or in iTunes?
OGG was built as a freely usable format and never gained support in Apple's software, so iPhones, iTunes, and Apple Music don't recognize it. Converting to M4A is the fix.
Can I convert OGG to M4A without uploading the file anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it's never sent over the internet. You could disconnect from wifi and it would still work.
Morphjet converts OGG, M4A, and 1,800+ other formats, all on your machine. Launching this July.
