Reading QR codes on a PC
Phone camera apps read QR codes instantly, but QR codes on a PC screen or in received screenshots are harder. This tool reads QR codes from image files and paste (Ctrl+V) too.
Beware of QR phishing (quishing)
Fake QR codes disguised as parking violation notices or delivery messages are increasing. This scanner shows the address in the QR first instead of opening it, so check it's the official site before opening.
