Why doesn't this work in my browser?

It relies on the BarcodeDetector API, currently supported in Chrome and Edge (desktop and Android) but not yet in Firefox or Safari — try one of those browsers if scanning fails.

Is my image uploaded to a server?

No — decoding happens locally using your browser's built-in API; the image is never sent anywhere.
