QR Generator Guide

Keep your content short, your contrast strong, and your quiet zone clean for reliable scans.

Focus
High contrast is the single most important QR rule
Best For
Use quiet zones so scanners can isolate the code
Tip
Keep URLs short to reduce code density

Pick the right content type

URLs, plain text, Wi-Fi, and contact cards all create different QR structures and different scan experiences.

  • Use URL for landing pages and sharing
  • Use Wi-Fi for guest network access
  • Use vCard for business cards and contact sharing

Improve scan reliability

A QR code should stay simple, quiet, and high-contrast so phones can read it in real-world lighting.

  • Use a dark foreground on a light background
  • Leave white space around the code
  • Test with at least two devices before printing

Common mistakes

Most failed scans come from overly dense content, weak contrast, or codes that are printed too small.

  • Do not place the code too close to other graphics
  • Do not shrink printed codes too aggressively
  • Do not use long URLs without shortening first
