About QR Code Generator
This QR Generator creates high-quality 2D barcodes for URLs, text messages, and WiFi QR connection strings. It is a versatile tool to share links and data instantly with mobile users, enabling seamless network onboarding and information exchange.
Bridge the physical and digital worlds. A QR code is the standard for contactless interaction, perfect for restaurant menus, business cards, or event ticketing. Ensuring your codes are scannable and high-contrast is critical for user experience.
Select the data type: URL, Text, or WiFi. Enter the relevant information, such as the SSID and password for networks. The QR code updates instantly. You can save it as a PNG or SVG for print-quality resolution.
Under the Hood
QR generation utilizes `qrcode.react`, which implements the ISO/IEC 18004 standard. It handles Reed-Solomon error correction (Levels L, M, Q, H), allowing the code to remain scannable even if partially obscured. The output is drawn to an HTML5 Canvas element for download or rendered as an SVG for vector scalability. For WiFi, it constructs the standard `WIFI:T:WPA;S:MyNet;P:Pass;;` string format.
