QR Code Generator Guide

This tool creates a QR code from a URL, text, email address, phone number, or other short payload. QR codes are helpful for menus, posters, event check-ins, product labels, and quick sharing from print to phone.

How to Use It

  1. Enter the destination text or URL.
  2. Choose size, color, and error correction if available.
  3. Generate the QR code and test it with more than one phone.
  4. Use high contrast and leave quiet space around the code before printing.

QR Code Best Practices

  • Use short URLs when possible because dense QR codes are harder to scan.
  • Keep strong contrast between foreground and background.
  • Do not place a QR code on a busy image without a clear border.
  • Test the final printed size from the actual viewing distance.
