About the M4A to OGG Converter
This M4A to OGG converter turns audio files from M4A into OGG without installing software or uploading anything. It solves a common problem: some car stereos, Android apps and editors will not play M4A. Converting to OGG gives you open Ogg Vorbis audio, ideal for games (Unity, Godot), open-source apps, Wikipedia and web audio.
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 M4A to OGG Converter
- Click "Choose files" or drag your M4A audio files onto the box. You can add several at once.
- Choose the OGG bitrate: 128 kbps for speech, 192 kbps for music or 320 kbps for the best quality.
- Press "Convert to OGG". The conversion runs on your device and shows its progress.
- Download each OGG file, or use "Download all (ZIP)" when you converted several.
- Open the result in VLC or Firefox to check it; your original M4A is never changed.
Tips & benchmarks
- Ogg Vorbis at 160 kbps sounds close to a 192 kbps MP3 and is ideal for game audio.
- 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 OGG to a website or government portal.
