What are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that can store various types of information including URLs, text, contact information, WiFi credentials, and more. Originally developed in 1994 for automotive manufacturing, QR codes have become ubiquitous in marketing, payments, and digital communication.

How QR Codes Work

QR codes use a matrix of black and white squares to encode data in a format that can be quickly read by smartphones and dedicated scanners:

• Data Encoding: Information is converted into a binary pattern
• Error Correction: Reed-Solomon error correction allows reading damaged codes
• Pattern Recognition: Finder patterns help scanners locate and orient the code
• Data Extraction: Scanners decode the pattern back into readable information

Supported Content Types

Website URLs

The most common use case for QR codes is linking to websites:

• Landing pages and promotional sites
• Product information and catalogs
• Social media profiles
• Online menus and digital content
• App store download links

Contact Information (vCard)

• P: Password
• H: Hidden network (true/false)

Email and Phone

• Coordinates: geo:37.7749,-122.4194
• Google Maps: https://maps.google.com/?q=latitude,longitude
• Address: geo:0,0?q=123+Main+St,+City,+State

Customization Features

Color Customization

Personalize your QR codes with custom colors while maintaining scannability:

• High Contrast: Ensure sufficient contrast between foreground and background
• Brand Colors: Match your corporate identity and brand guidelines
• Color Psychology: Use colors that align with your message and audience
• Accessibility: Consider color-blind users and low-vision accessibility

Logo Integration

Add your logo or brand elements to QR codes:

• Size Recommendations: Keep logos under 30% of total QR code area
• Error Correction: Use higher error correction levels when adding logos
• Placement: Center placement works best for logo integration
• Background: Ensure logo has sufficient contrast and background

Size and Resolution Options

Choose appropriate dimensions for your use case:

• Digital Display: 256x256px for websites and social media
• Print Materials: 512x512px or higher for business cards and flyers
• Large Format: 1024x1024px or 2048x2048px for posters and banners
• Minimum Size: Ensure QR codes are at least 2cm (0.8 inches) when printed

Error Correction Levels

Understanding Error Correction

QR codes include built-in error correction using Reed-Solomon error correction codes, allowing them to be read even when partially damaged or obscured:

Export Formats and Applications

PNG Format

PNG (Portable Network Graphics) is ideal for most digital applications:

• Lossless compression maintains perfect quality
• Transparency support for flexible placement

JPEG Format

JPEG is suitable when file size is a primary concern:

• Smaller file sizes for web optimization
• Adjustable quality settings for size/quality balance
• Universal compatibility across all devices and platforms
• Note: Avoid heavy compression as it may affect scannability

SVG Format

SVG (Scalable Vector Graphics) offers infinite scalability:

• Vector-based graphics scale without quality loss
• Small file sizes for simple QR codes
• Editable in vector graphics software
• CSS styling possibilities for web integration
