How to create a QR code

  1. Choose the QR type based on your need, such as website, Wi-Fi, contact, or UPI.
  2. Enter all required details and verify that the preview matches your content.
  3. Apply a preset, then tune shape, colors, frame, quiet zone, and logo size.
  4. Check scan quality metrics and warnings before final download.
  5. Choose PNG, SVG, or PDF and test scan before sharing or printing.

Best practices for QR code scanning

  • Keep strong foreground and background contrast.
  • Use at least 4 modules quiet zone and avoid noisy backgrounds.
  • Do not cover finder eyes or large portions with logos.
  • Use larger output size for long payloads or dense event/contact data.
  • Test with both Android and iPhone camera apps.

When to use high error correction

Use Level H when you add logos, use decorative shapes or gradients, or plan outdoor print placement. Use Level Q for most standard posters and digital sharing.

Common QR code types

Website and URL QR for links, text QR for notes, Wi-Fi QR for instant network join, vCard QR for contact cards, location QR for map points, event QR for calendar entries, and UPI QR for payment requests.
