Customization Options

Colors

Change the foreground and background colors to match your brand. Dark foreground on light background works best for scanning reliability.

Error Correction

QR codes have built-in error correction:

• Low (L): Recovers 7% of data — smallest QR code
• Medium (M): Recovers 15% — good default
• Quartile (Q): Recovers 25% — works with some damage
• High (H): Recovers 30% — works even if partially covered

Use higher error correction if the QR code will be printed small, placed on curved surfaces, or might get partially obscured.

Size

Generate QR codes from 128x128px (social sharing) to 1024x1024px (print materials). For print, use at least 300 DPI.

QR Code Best Practices

1. Test before printing — Always scan your QR code with multiple phones before mass printing
2. Use short URLs — Shorter data = simpler QR code = easier to scan
3. Add a call-to-action — Don't just show a QR code; add text like "Scan to see menu"
4. Maintain contrast — Dark code on light background. Avoid low-contrast color combinations
5. Include a quiet zone — Leave white space around the QR code (at least 4 modules wide)
6. Consider a URL shortener — Use our URL Shortener to create trackable short links, then encode those in your QR code
