QR codes (Quick Response codes) are two-dimensional barcodes that can store various types of data including URLs, text, contact information, and WiFi credentials. Invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become ubiquitous in modern life for payments, marketing, authentication, and information sharing. This tool generates QR codes entirely in your browser — no data is sent to any server. The generated codes can be scanned by any smartphone camera or QR code reader app.
