QR Code Generator
Make QR codes for links, Wi-Fi, contacts and more. Everything runs in your browser and nothing is uploaded.
Before you print: scan it with two different phones. Keep the quiet zone, print it at least 2 cm wide, and use dark code on a light background.
Changing links later: a QR code can't be edited once printed. If the destination might change, point it at a short link you control and redirect from there.
