📱 What is a QR Code?
QR Code (Quick Response Code) is a two-dimensional barcode that can store various types of data—URLs, text, contact information, WiFi credentials, and more. Invented in 1994 by Denso Wave in Japan, QR codes are now ubiquitous in marketing, payments, authentication, and everyday life.

🛡️ QR Code Best Practices
1. Test Before Printing
Always test your QR code with multiple devices and scanning apps before mass printing or distribution.
2. Maintain High Contrast
Use dark colors on light backgrounds (or vice versa) for optimal scanning. Avoid low-contrast combinations.
3. Add a Call-to-Action
Include text like "Scan for menu" or "Scan to connect" to tell users what they'll get by scanning.
4. Size Matters
Minimum size: 2x2 cm (0.8x0.8 inches) for close-range scanning. Larger for distance scanning (billboards, posters).
5. Use Error Correction Wisely
Higher error correction (H) allows up to 30% damage but creates denser codes. Use M or Q for most cases.
6. Keep URLs Short
Shorter URLs create simpler QR codes that scan faster. Use URL shorteners like bit.ly or TinyURL if needed.
❓ Frequently Asked Questions
Are QR codes free to use?
Yes! QR codes are an open standard (ISO/IEC 18004) and free to generate and use. Our tool has no limitations or watermarks.
Do QR codes expire?
Static QR codes (like ours) never expire. The code itself is permanent. However, if you link to a URL, that URL must remain active.
Can I track QR code scans?
Static QR codes cannot be tracked. For analytics, use dynamic QR codes (paid services) or add UTM parameters to your URLs for Google Analytics tracking.
What's the difference between static and dynamic QR codes?
Static QR codes (ours) encode data directly and can't be changed. Dynamic QR codes redirect through a URL shortener, allowing you to change the destination and track scans.
Can I add a logo to my QR code?
Yes, but carefully! Logos can be added to the center (up to 30% coverage with high error correction). Use image editing software to overlay your logo.
What apps can scan QR codes?
Most modern smartphones have built-in QR scanners in the camera app (iOS 11+, Android 9+). Third-party apps include Google Lens, QR Code Reader, and more.
Are QR codes secure?
QR codes themselves are just data containers. Security depends on the content. Always verify the destination URL before visiting, and be cautious of QR codes from unknown sources (QR phishing/"quishing").
What's the best format for printing?
Use SVG or PDF for print materials (business cards, posters, banners) as they're vector formats that scale without quality loss. Use PNG for digital displays.
