About Generator Kode QR
OptiPix QR Code Generator lets you create and scan QR codes entirely in your browser. Generate QR codes from URLs, plain text, email addresses, phone numbers, WiFi credentials, or any text content. Customize the output with adjustable size, error correction level, and foreground/background colors. The generator produces crisp, high-resolution QR codes that you can download as PNG images. The built-in scanner uses your device's camera or lets you upload an image containing a QR code to decode its content. Both generation and scanning happen locally with no server interaction. QR codes are widely used for contactless menus, event tickets, business cards, WiFi sharing, payment links, and marketing campaigns. The tool supports all standard QR code error correction levels (L, M, Q, H) so codes remain scannable even if partially damaged or obscured.
How It Works
The generator uses the qrcode library to encode your text into a QR code matrix following the ISO/IEC 18004 standard. The scanner uses the jsQR library to detect and decode QR codes from images using pattern recognition algorithms.
