OGG to AAC Converter
Turn your OGG file into a smaller, efficient AAC file — the format used across Apple devices, streaming platforms, and most modern apps. It's converted right on your own device, so the audio file itself is never sent anywhere.
Processed locally on your device — your file is never uploaded. Max file size: 100MB.

How It Works
1
Pick Your File
Select the OGG you'd like to convert. It never leaves your device at any point in the process.
2
On-Device Encoding
Your browser encodes the audio into AAC. A small WebAssembly compatibility engine loads first — either way, nothing is sent to a server.
3
Save Your File
Download your new AAC file — typically smaller than the original OGG and ready for phones, apps, or streaming.
Common Questions
Yes. There are no limits, sign-ups, or fees. Conversion happens in your browser, so there's no server cost to pass on.
No. The OGG file is decoded and re-encoded entirely on your own device using WebAssembly. It's never transmitted to this or any other server.
Any modern browser with WebAssembly support — current versions of Chrome, Firefox, Edge, and Safari all work.
