What are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that can store various types of information including URLs, text, contact information, Wi-Fi credentials, and more. They were originally developed for tracking parts in automotive manufacturing but have become ubiquitous in marketing, payments, and everyday convenience applications.

QR codes can be scanned quickly using any smartphone camera, making them an efficient bridge between physical and digital worlds. They're used in advertising, product packaging, business cards, event tickets, restaurant menus, and countless other applications.

Our QR code generator and scanner allows you to create custom QR codes for any purpose, with options for different error correction levels, sizes, and formats to suit your needs. You can also scan existing QR codes using your device's camera to quickly access the encoded information.

How QR Code Generation and Scanning Works

QR Code Generation: Our QR code generator creates QR codes by:

  1. Input Processing: Takes your input (URL, text, email, etc.) and converts it to QR code data format
  2. Error Correction: Adds error correction data based on your selected level (L, M, Q, or H) to ensure scannability even if the code is damaged
  3. Pattern Generation: Creates the characteristic square pattern with finder patterns, alignment patterns, and data modules
  4. Customization: Applies your selected colors, size, and styling options
  5. Export: Generates the QR code in your preferred format (PNG, SVG, or JPG) ready for download

QR Code Scanning: Our QR code scanner uses your device's camera to:

  1. Camera Access: Requests permission to use your device's camera for real-time scanning
  2. Pattern Recognition: Analyzes the camera feed to detect QR code patterns in real-time
  3. Data Extraction: Decodes the QR code and extracts the encoded information
  4. Result Display: Shows the scanned content, which you can copy or use directly

All QR code generation and scanning happens in your browser - your data is never sent to our servers, ensuring complete privacy and security.

Common QR Code Use Cases
