What QR Codes Can Encode
- Website URLs: Most common use — link directly to any webpage, product, or landing page
- Plain text: Any text up to ~2,900 characters
- Contact info (vCard): Name, phone, email, address — scanning adds the contact directly to the phone
- Wi-Fi credentials: Network name and password — scanning connects automatically without typing
- Email address: Opens a compose window with the address pre-filled
- Phone number: Opens the dialer with the number ready to call
- SMS message: Opens a text message to a specific number with optional pre-filled text
- Geographic coordinates: Opens map apps to a specific location
QR Code Error Correction Levels
QR codes include built-in error correction that allows them to scan even when partially damaged or obscured. Four levels of error correction:
- L (Low): 7% damage recovery — smallest file size, easiest to scan
- M (Medium): 15% damage recovery — good general use
- Q (Quartile): 25% damage recovery — recommended for printed materials
- H (High): 30% damage recovery — best for codes that may be partially covered (e.g., with a logo overlay)
Print Resolution Guidelines
For reliable scanning, print QR codes at a minimum of 200 DPI. Recommended minimums by use case:
- Business cards: 300 DPI, minimum size 2 × 2 cm
- Flyers and brochures: 300 DPI, minimum 3 × 3 cm
- Posters (scanned from distance): 150+ DPI, minimum 8 × 8 cm
- Billboards and signage: Scale proportionally — should be scannable from viewing distance
Always test your printed QR code with multiple devices before distributing. Android and iOS have different camera apps with slightly different QR decoding behaviors.

Can I customize the appearance of a QR code?
Our generator produces standard black-and-white QR codes optimized for maximum scan reliability. Custom colors are possible but reduce contrast and reliability. If you add a logo overlay, use High (H) error correction level so the code remains scannable despite the covered area.
Are QR codes safe to scan?
QR codes themselves are not dangerous, but they can link to malicious websites — just like any link. Be cautious scanning QR codes in unexpected places (stickers on ATMs, unsolicited emails, etc.). Always preview the URL before opening if your scanning app supports it.
Do QR codes expire?
Static QR codes (like those generated by our tool) never expire — the code simply encodes a URL or text directly. As long as the linked URL or content remains accessible, the code works indefinitely. "Dynamic" QR codes from paid services can be changed after printing but require a subscription.
