About the OGG to M4A Converter
This OGG to M4A converter turns audio files from OGG into M4A without installing software or uploading anything. It solves a common problem: iPhones and many car stereos do not play OGG. Converting to M4A gives you AAC audio in M4A for Apple devices, ideal for iPhone, iTunes and Apple Music libraries and voice memos.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your audio files are never uploaded, stored or seen by anyone else, which makes it safe for voice recordings, interviews and unreleased music.
What to expect: the sample rate and channels are kept, and you can pick the bitrate; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the OGG to M4A Converter
- Click "Choose files" or drag your OGG audio files onto the box. You can add several at once.
- Choose the M4A bitrate: 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality.
- Press "Convert to M4A". The conversion runs on your device and shows its progress.
- Download each M4A file, or use "Download all (ZIP)" when you converted several.
- Open the result in iPhone or iTunes to check it; your original OGG is never changed.
Tips & benchmarks
- AAC in M4A sounds better than MP3 at the same bitrate; 160–192 kbps is excellent for music.
- As a guide, one minute of audio at 128 kbps is about 1 MB, and at 320 kbps about 2.4 MB.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the M4A to a website or government portal.
Frequently asked questions

Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed. The audio and video engine is a larger download the first time, so Wi-Fi is recommended.
What is the difference between OGG and M4A?
OGG (Ogg Vorbis) is a open compressed audio best suited to games (Unity, Godot), open-source apps, Wikipedia and web audio. M4A (MPEG-4 Audio) is a AAC audio in an MP4 container best suited to iPhone, iTunes and Apple Music libraries and voice memos.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
