URL QR Codes
The most common use for QR codes is linking to websites. Simply enter any URL and generate a scannable code that takes users directly to that page.
- Enter the full URL including https://
- Shorter URLs create simpler, more scannable codes
- Consider using a URL shortener for very long links
- Test the code before printing or publishing
Use cases: Business cards, flyers, product packaging, restaurant menus, event posters, and anywhere you want to bridge print and digital.
WiFi Sharing
Create QR codes that allow guests to instantly connect to your WiFi network without typing passwords. This is perfect for homes, offices, cafes, and events.
Required Information
- Network name (SSID) - Your WiFi network name
- Password - The network password
- Security type - WPA/WPA2 (most common), WEP, or None
- Hidden network - Check if your network is hidden
When scanned, the user's phone will prompt them to connect to the network automatically. Supported on iOS 11+ and Android 10+.
Contact vCards
vCard QR codes contain contact information that can be saved directly to a phone's contacts app with one scan.
Available Fields
- Full name and title
- Organization/company
- Phone numbers (work, mobile, home)
- Email addresses
- Website URLs
- Physical address
- Notes
Tip: Only include essential information. More data means a more complex QR code that may be harder to scan, especially at smaller sizes.
Customization Options
Colors
Customize your QR code colors to match your brand:
- Foreground color - The color of the QR code modules (dots)
- Background color - The background behind the code
Important: Maintain sufficient contrast between foreground and background. Dark foreground on light background works best. Avoid light colors for the foreground as they may not scan reliably.
Size
Download your QR code at various sizes:
- Small (200px) - Digital use, social media
- Medium (400px) - Business cards, small prints
- Large (800px) - Posters, signage
- Custom - Specify exact pixel dimensions
For print, ensure adequate resolution. A QR code on a poster should be at least 2cm x 2cm at the minimum scanning distance.
Logo Overlay
Add your logo or icon to the center of the QR code for branded appearance. This works because QR codes have built-in error correction that allows part of the code to be obscured.
Best Practices for Logos
- Keep the logo small (under 30% of QR code area)
- Use a simple, recognizable icon or logomark
- Ensure there's contrast between logo and QR code
- Square or circular logos work best
- Add a small white border around the logo for clarity
Always test QR codes with logos to ensure they still scan correctly. Use higher error correction levels when adding logos.
Error Correction Levels
QR codes include redundant data that allows them to be read even if partially damaged or obscured. Higher error correction means more reliability but also larger (more complex) codes.
| Level | Recovery Capacity | Best For |
|---|---|---|
| L (Low) | ~7% | Clean digital displays, maximum data capacity |
| M (Medium) | ~15% | General purpose, good balance (default) |
| Q (Quartile) | ~25% | Outdoor use, some wear expected |
| H (High) | ~30% | Logo overlays, harsh conditions |
Recommendations:
- Use Level M for most digital and print applications
- Use Level H when adding a logo overlay
- Use Level Q or H for outdoor signage or labels that may get dirty
- Use Level L only when you need to encode maximum data in minimum size
Remember: higher error correction creates denser codes that require larger physical sizes for reliable scanning.
