QR Code Generator

A QR code (Quick Response code) is a two-dimensional barcode that stores data in a matrix of black and white squares. Unlike traditional one-dimensional barcodes, QR codes use both horizontal and vertical patterns to encode up to 4,296 alphanumeric characters. They were invented in 1994 by Denso Wave to track vehicle parts during manufacturing.

Modern smartphones can scan QR codes natively through their camera apps, without any dedicated app required. This makes QR codes one of the most accessible ways to bridge physical materials and digital content. The built-in error correction means a QR code can still be scanned even when up to 30% of it is obscured or damaged.

QR codes have practical applications across many industries. Restaurants embed them on table cards to link to digital menus. Businesses print them on flyers, packaging, and signage to direct customers to a website, app download, or promotional page. Event organisers use QR codes on tickets and badges to speed up check-in. Real estate agents place them on property listings so buyers can immediately access full details on their phones.

For individuals, QR codes make sharing contact information, Wi-Fi passwords, and links effortless. Any situation where typing a URL would be inconvenient for someone without a keyboard is a natural use case for a QR code. Our generator creates a downloadable QR code image you can use in any digital or print context.
