Tips
- Ensure Strong Contrast: For reliable scanning, use high contrast between foreground and background colors (e.g., dark code on a light background).
- Mind the Quiet Zone: Leave a clear border around the QR pattern to improve scan reliability.
- Balance Logo Size: If embedding a logo, keep it small enough not to obscure critical QR modules; test across devices.
- Use Adequate Error Correction: For codes with logos or small sizes, select a higher error correction level to compensate for potential data loss.
- Prefer Vector Outputs for Printing: Export SVG (or PDF) when printing large formats to maintain sharp edges and scalability.
- Test Thoroughly: Always test the generated QR codes with multiple devices and scanning apps before launching a campaign.
- Brand Consistency: Use consistent color palettes and logo placements to reinforce brand recognition across all QR codes.
