Upload a photo with a QR code

Press "Scan with Camera" and allow camera access, then hold the QR code in front of it.
Or upload a photo that has a QR code.
Copy the result, or open it if it is a link.

Privacy: scanning happens on your device — your photo is never uploaded anywhere. Be careful before opening links from unknown QR codes.
