QR Code Generator

QR Code Generator Interface

I built a modern, feature-rich QR code generator that goes beyond basic functionality. Users can create QR codes for URLs, text, emails, phone numbers, and WiFi credentials with custom colors, logos, and high-quality output options. The clean, intuitive interface makes professional QR code creation accessible to everyone.

Challenge & Solution

Most QR code generators are either too basic or overwhelming with ads and limitations. Users needed a clean, professional tool that could handle multiple data types while offering customization options for branding and quality control.

I created a comprehensive solution that balances powerful features with an elegant user experience:

  • Multi-Format Support: Built support for URLs, plain text, email addresses, phone numbers, and WiFi credentials with proper data validation and formatting.
  • Custom Branding: Implemented logo overlay functionality with a curated selection of default icons plus custom upload capability for personalized branding.
  • Color Customization: Added foreground and background color controls allowing users to match their brand colors while maintaining QR code readability.
  • Quality Control: Integrated adjustable resolution settings from 300px to 2000px for everything from web use to print-ready materials.
  • Intuitive Interface: Designed with collapsible sections, real-time preview, and smart form validation for a smooth user experience.
