What is QR Code Generator?

QR Code Generator is an online tool that creates scannable QR codes from text, URLs, email addresses, phone numbers, and WiFi credentials. QR codes encode information in a two-dimensional barcode that smartphones can read instantly — no typing required.

Businesses use QR codes for marketing campaigns, restaurant menus, event tickets, and product packaging. Developers embed them in documentation, share WiFi passwords at conferences, and create deep links for mobile app onboarding. A good generator lets you preview and download high-quality PNG images.

WaiHub's QR Code Generator supports five content types with live preview and PNG download. WiFi codes use the standard WIFI: format so guests scan and connect automatically. URLs auto-prefix https:// when missing. All generation happens in your browser — no data upload.
