QR Code Generator: free online, fast and secure
QR codes connect print to phone in one scan: shop payments, menus, visiting cards, product packaging and posters. This generator creates static QR codes that never expire and do not track your customers.
Create a link or text QR, a UPI payment QR with your UPI ID and optional amount, a Wi-Fi QR that connects guests without typing a password, or a WhatsApp chat QR. Choose colours, size and error correction, and download PNG or SVG for print.
