About QR Codes
QR (Quick Response) codes were invented in 1994 by Denso Wave for tracking automotive parts. Today they are used worldwide for contactless payments, restaurant menus, event tickets, WiFi sharing, and linking to websites. A QR code stores data in a two-dimensional grid of black and white squares that can be read by any smartphone camera.
This generator creates QR codes entirely in your browser using JavaScript and the HTML5 Canvas API. No data is sent to any server. The generated codes follow the QR code standard and include error correction, making them readable even if partially damaged. You can encode URLs, plain text, WiFi network credentials, or pre-composed emails.
