How to Create Effective QR Codes
Choosing the Right Size
Select the appropriate size based on where your QR code will be displayed:
- Small (128×128): Digital use only (websites, emails, digital documents)
- Medium (256×256): Business cards, flyers, small posters
- Large (512×512): Posters, banners, outdoor signage
- Extra Large (1024×1024): Large format printing, billboards, distant viewing
Tip: Keep data short for better scannability. URLs create simpler patterns than long text or detailed contact information.
Color Selection Best Practices
For reliable scanning across all devices:
- Use dark foreground colors (black, dark blue, dark green)
- Use light background colors (white, light gray, light yellow)
- Maintain high contrast between foreground and background
- Avoid similar colors (e.g., dark blue on black, yellow on white)
- Test your color combination before final printing
Download Format Guide
- PNG: Best for most uses - high quality, transparent backgrounds, universal compatibility
- SVG: Vector format for scalable printing - ideal for large format or professional printing
- JPEG: Smaller file size for web use where transparency isn't needed
Printing QR Codes
Minimum Print Sizes
- Business cards: 2×2 cm (0.8×0.8 inches) minimum
- Flyers and posters: 3×3 cm (1.2×1.2 inches) or larger
- Outdoor signage: Use 10% rule (viewed from 10 feet = 1 foot QR code)
White Space (Quiet Zone)
Leave blank space around your QR code equal to at least four squares from the pattern edge. This quiet zone helps scanners detect the code boundaries.
Before You Print
Test your QR code with multiple smartphones at the actual size and distance it will be scanned. Verify the link or information is correct before mass printing.

Privacy & Security
Your Data is Private
This tool runs entirely in your browser. No data is sent to any server. Your QR codes are generated locally on your device.
What Not to Encode
Never put sensitive information in QR codes: passwords, credit card numbers, social security numbers, or private keys. QR codes are not encrypted - anyone who scans them can see the content.
Scanning Safety
Only scan QR codes from trusted sources. Malicious codes can link to phishing sites or malware. Most phones preview the URL before opening - always check the destination before proceeding.
