QR Code Generator creates QR codes from text, URLs, contact cards (vCard), WiFi credentials, email addresses, and phone numbers. It supports customizable error correction levels (L, M, Q, H), foreground and background colors, output size, and margin settings. Higher error correction levels allow QR codes to remain scannable even when partially obscured or damaged, at the cost of increased data density.
Marketing teams creating print materials, event organizers building check-in systems, and businesses adding contactless information sharing to physical products. The tool runs entirely in your browser — your data never leaves your device.
