Complete Guide to QR Code Customization
Transform plain black-and-white QR codes into branded, eye-catching designs that maintain perfect scannability.
Why Customize Your QR Codes?
A customized QR code does more than just link to a destination. It reinforces your brand, attracts attention, and builds trust with your audience. Studies show that branded QR codes receive up to 80% more scans than plain black-and-white versions.
Brand Recognition
Custom colors and logos make your QR codes instantly recognizable as part of your brand.
Increased Trust
Branded QR codes appear more professional and trustworthy to users.
Higher Engagement
Eye-catching designs attract more scans and improve campaign performance.
Color Customization
Color is the most impactful customization option. The right color scheme can make your QR code stand out while maintaining excellent scannability.
Foreground Colors
The foreground color is the color of the QR code modules (the squares). Best practices for foreground colors:
- Use dark colors for maximum contrast
- Black, navy blue, dark green, and deep purple work well
- Avoid light colors like yellow, light gray, or pastels
- Match your brand's primary or secondary colors
Background Colors
The background should always be lighter than the foreground:
- White is the safest and most reliable choice
- Light colors like cream, light gray, or pale brand colors work well
- Transparent backgrounds are possible for overlays
- Avoid dark backgrounds with light foreground colors
Contrast Rule
Always maintain at least a 4:1 contrast ratio between foreground and background colors. Use online contrast checker tools to verify your color combinations.
Adding Logos to QR Codes
Logos are a powerful way to brand your QR codes. When done correctly, a centered logo can increase scan rates significantly. For detailed instructions, see our guide on adding logos to QR codes safely.
Logo Size Guidelines
- Maximum size: 30% of the QR code area
- Recommended size: 15-25% for optimal balance
- Minimum padding: Leave space around the logo
- Shape: Square or circular logos work best
Logo Format Tips
- Use PNG or SVG for best quality
- Ensure transparent backgrounds if needed
- Simplify complex logos for small sizes
- Test with high error correction (H level)
Dot and Corner Styles
Beyond colors and logos, you can customize the shape of individual QR code elements for a unique look.
Dot Patterns
Available dot styles and their characteristics:
- Square: Classic, professional, highest reliability
- Rounded: Softer, modern look
- Circle: Contemporary, friendly appearance
- Diamond: Unique, eye-catching
- Star: Decorative, lower reliability
Corner Eye Styles
The three large squares in the corners (finder patterns) can also be customized:
- Keep the outer square visible for scanner recognition
- Inner elements can use different colors or shapes
- Maintain contrast between inner and outer elements
Error Correction Levels
Error correction determines how much of the QR code can be damaged or obscured while still scanning. Higher levels are essential for customized codes.
| Level | Recovery | Best For |
|---|---|---|
| L (Low) | ~7% | Plain codes, minimal customization |
| M (Medium) | ~15% | Color changes, simple designs |
| Q (Quartile) | ~25% | Small logos, complex patterns |
| H (High) | ~30% | Large logos, heavy customization |
Recommendation: Use Level H for any QR code with a logo, and at least Level M for color customizations.
Testing Your Customized QR Code
Always test your customized QR code before printing or publishing. Follow this testing checklist:
- Scan with at least 3 different smartphones (iOS and Android)
- Test in various lighting conditions
- Try scanning from different distances
- Print a test version at your intended size
- Have someone unfamiliar with the code test it
