Frequently Asked Questions

A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of black and white squares. Originally created for tracking automotive parts, QR codes now encode URLs, contact info, WiFi credentials, payment data, and much more.

Our generator creates ISO/IEC 18004 compliant codes that work universally with all standard QR readers and smartphone cameras—no special app required.

We've built a professional-grade tool that's completely free and accessible to everyone:

• Unlimited generation with zero restrictions or hidden fees
• High-resolution exports up to 4K for crisp printing
• Advanced styling options: colors, logos, frames, and patterns

Quality that rivals expensive professional tools, with the simplicity and accessibility everyone deserves.

Our platform supports all popular QR code types for different use cases:

• URL Codes: Website links, landing pages, and social media profiles
• Contact Cards: vCard format with name, phone, email, and address
• WiFi Credentials: Network name, password, and security type for instant connection

We generate codes following international standards, ensuring universal compatibility across all devices and applications worldwide.

• URL/Website links
• Plain text messages
• Email addresses
• Phone numbers & SMS
• WiFi networks
• vCard contacts

All codes include configurable error correction, enabling them to function even if partially damaged or obscured.

Creating a QR code is incredibly straightforward—no technical knowledge needed:

• 1. Choose Content Type: Select URL, text, vCard, WiFi, or another format
• 2. Enter Your Data: Type or paste the information you want to encode
• 3. Customize Appearance: Optional: Add colors, logos, frames, and styling
• 4. Generate & Download: Click generate and download in your preferred format
• 5. Test Your Code: Scan with your phone to verify it works correctly
• Done!: Use your code digitally or print it for physical applications

Follow these guidelines to ensure reliable scanning and professional appearance:

• Sufficient Size: Minimum 2x2 cm (0.8x0.8 inches) for reliable scanning at typical distances
• High Contrast: Dark codes on light backgrounds work best—ensure at least 70% contrast difference
• Test Before Distributing: Always scan your codes with multiple devices before printing or sharing widely

Pro tip: QR codes with high error correction (Level H) can still scan even if up to 30% of the code is damaged or obscured.
