Customization Options
Colors & Styling
- •Foreground Color: The dark pattern/data modules of the QR code
- •Background Color: The light background area around the pattern
- •Transparent Background: Remove background for overlay on images
- •Contrast Requirement: Maintain minimum 4.5:1 contrast ratio for scannability
Error Correction Levels
L - Low (7%)
Best for digital use only. Smallest QR code size.
M - Medium (15%)
Good balance. Recommended for general use.
Q - Quartile (25%)
Higher reliability. Recommended for print.
H - High (30%)
Maximum protection. Allows logos up to 30%.
Size & Format Options
- •PNG: Raster format in 256px, 512px, 1024px, 2048px (recommended for most uses)
- •SVG: Vector format that scales infinitely (best for print and large displays)
- •PDF: Print-ready format with centered layout
- •JPEG: Compressed format (not recommended for QR codes)
- •WebP: Modern web format with better compression
Best Practices
✓ Test Before Printing
Always test your QR code with multiple devices and scanner apps before printing or distributing. Our scannability checker provides instant feedback.
✓ Maintain Sufficient Contrast
Ensure at least 4.5:1 contrast ratio between foreground and background. Avoid light colors on light backgrounds or dark on dark.
✓ Size Appropriately
Minimum print size: 2cm x 2cm (0.8" x 0.8"). For viewing from 1 meter away, use at least 3cm x 3cm. Use our size calculator for precise dimensions.
✓ Include a Call-to-Action
Always add text explaining what users will get by scanning: "Scan for Menu", "Get 10% Off", "View Our Portfolio"
✓ Consider Placement
Place QR codes at eye level when possible. Avoid curved surfaces, reflective materials, or areas with poor lighting.
✓ Use High Error Correction for Logos
If adding a logo, use error correction level H and keep logo size under 30% of QR code area.
Troubleshooting
❌ QR Code Won't Scan
Possible causes:
- • Insufficient contrast between foreground and background
- • QR code too small for scanning distance
- • Too much data encoded (keep URLs short)
- • Poor lighting conditions
- • Damaged or distorted QR code
❌ Low Scannability Score
Solutions:
- • Increase contrast ratio (aim for 7:1 or higher)
- • Increase QR code size
- • Use higher error correction level
- • Reduce data complexity (shorten URLs)
- • Ensure adequate margin/quiet zone
❌ Print Quality Issues
Solutions:
- • Use SVG format for scalable vector graphics
- • Download at least 2048px for high-quality prints
- • Ensure printer resolution is at least 300 DPI
- • Avoid JPEG compression artifacts
- • Test print a sample first

Frequently Asked Questions
Are the QR codes free to use commercially?▼
Yes! All QR codes generated on our platform are completely free to use for both personal and commercial purposes. There are no restrictions or licensing fees.
Do QR codes expire?▼
Static QR codes (like the ones we generate) never expire. They contain the actual data encoded within them, so they'll work forever as long as the image remains intact.
What's the maximum data a QR code can hold?▼
QR codes can technically hold up to 4,296 alphanumeric characters. However, for optimal scannability, we recommend keeping URLs under 100 characters and other data as concise as possible.
Can I edit a QR code after creating it?▼
Static QR codes cannot be edited once created. If you need to change the destination or content, you'll need to generate a new QR code. For editable QR codes, consider using our dynamic QR feature (coming soon).
Why won't my QR code scan?▼
Common issues include poor contrast, insufficient size, too much data, or environmental factors like poor lighting. Use our scannability checker to diagnose and fix issues before printing.
