How to Generate a QR Code – Create Free QR Codes Online in Seconds

What Is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that stores information in a square grid of black-and-white pixels. Unlike a traditional barcode, which only holds data in a single line, a QR code stores data both horizontally and vertically, allowing it to hold far more information in a much smaller space.

QR codes are used in:

• Marketing and advertising
• Restaurant menus
• Payment systems
• Product packaging
• Event ticketing
• Business cards
• WiFi sharing
• Educational materials
• App downloads

Every day, millions of smartphones scan QR codes to instantly open websites, view menus, connect to WiFi, or save contact details. Modern QR code generators support multiple data types for marketing, business, and personal use.
