What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that can be scanned by any smartphone camera to instantly access information — a URL, contact details, payment information or plain text. Invented in 1994 by Denso Wave in Japan for tracking automotive parts, QR codes are now ubiquitous in marketing, payments, menus, ticketing and more.

Frequently Asked Questions
How do I scan a QR code?On most Android and iPhone devices, open the Camera app and point it at the QR code — a link appears automatically. Alternatively, use Google Lens or any QR scanner app.
Do QR codes expire?Static QR codes (like the ones generated here) never expire. The data is embedded directly in the QR code image and has no expiry.
What size should I print my QR code?For easy scanning, print QR codes at a minimum of 2×2 cm. For outdoor use (banners, hoardings), use at least 10×10 cm. The minimum scanning distance is roughly 10× the QR code size.
Can I add a logo to the QR code?QR codes have built-in error correction (up to 30% of the code can be obscured and still scan). This allows logos to be overlaid on the centre of a QR code without breaking it — though this tool generates standard QR codes without logo overlay.
Is my data private when generating QR codes?Yes. QR codes are generated entirely in your browser. Your data is not sent to or stored on any server.
