QR Code Usage Tips

Best Practices

  • Test your QR code with different devices before printing
  • Use higher error correction for printed materials
  • Ensure good contrast between foreground and background
  • Keep QR codes at least 2cm x 2cm for reliable scanning
  • Avoid placing logos or text over the QR code pattern

Choosing Error Correction Level

Low (L): Best for digital displays where the QR code will be scanned without damage. Use for screens, presentations, or clean print environments.

Medium (M): Good balance for most uses. Handles minor damage or distortion well. Recommended for general purpose QR codes.

Quartile (Q): Better resistance to damage. Up to 25% of the code can be recovered if damaged. Good for printed materials that may wear.

High (H): Maximum error correction. Up to 30% can be damaged while still scannable. Best for printed materials, outdoor use, or when adding a logo overlay.

Common Use Cases

  • Website URLs: Direct users to your website with a single scan
  • Contact cards: Share your contact info instantly
  • Wi-Fi credentials: Let guests connect to your network automatically
  • SMS: Pre-compose text messages for marketing or support
  • Email: Open email client with pre-filled recipient and subject
  • Phone: Initiate a phone call with one tap

QR Code Generator FAQ

Is this QR code generator free?
Yes, our QR code generator is completely free to use with no limits on the number of QR codes you can create.
Is my data secure?
All QR code generation happens locally in your browser. Your data is never transmitted to any server and is not stored or logged.
What error correction level should I use?
Use Medium (M) for most cases. Use High (H) for printed materials or if you plan to add a logo overlay. Use Low (L) for digital displays only.
What size should I use for printing?
For print, use at least 512x512 pixels and ensure the printed size is at least 2cm x 2cm. Larger sizes (1024x1024) are better for posters and banners.
Can I use these QR codes commercially?
Yes, you can use generated QR codes for commercial purposes. There are no restrictions on usage.
How do I add a logo to my QR code?
Our generator does not embed logos directly. To add a logo, generate a QR code with High error correction, then use an image editor to place a small logo in the center. Keep the logo under 20% of the QR code area.
Can I generate static or dynamic QR codes?
Our generator creates static QR codes only. The encoded data is fixed and cannot be changed after generation. Dynamic QR codes require a server-side service.
Why won't my QR code scan?
Common issues: low contrast (use dark on light background), too small (under 2cm), damage or distortion, or incorrect data format. Test with multiple scanners before printing.
