About this tool

QR codes (Quick Response codes) are two-dimensional barcodes that can store URLs, text, WiFi credentials, contact information, and more. Our QR Code Generator creates real, scannable QR codes using the industry-standard qrcode library. Choose from 5 modes: URL (website links), plain text, WiFi (auto-connect with SSID, password, and encryption type), vCard (share contact details including name, phone, email, company, and website), and email (pre-filled recipient, subject, and body). Customize the error correction level (Low 7%, Medium 15%, Quartile 25%, High 30%) to balance between data density and scan reliability. Change foreground and background colors to match your brand, and download as PNG (raster) or SVG (vector, infinitely scalable). All QR codes are generated in your browser — no data is sent to any server.
