Frequently asked questions

How do I convert OGG to MP3?

Click “Choose Files” or drag your OGG file onto the page, optionally adjust the settings, then hit Convert. Your MP3 file downloads straight from your browser. Nothing is uploaded anywhere.

Is this OGG to MP3 converter free?

Yes, completely free with no hidden limits, watermarks or signup. Because all processing happens on your own device, there are no server costs to pass on to you.

Are my files uploaded to a server?

No. The conversion engine runs entirely in your web browser using WebAssembly. Your files never leave your device. You can even disconnect from the internet after the page loads and keep converting.

Is there a file size limit?

We impose no fixed limit. The practical ceiling is your device's free memory, since processing happens locally. Most conversions work comfortably with files up to a few hundred megabytes, and image or document conversions handle much more.
