## 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](https://www.razi.pro/tools/url-shortener) to create trackable short links, then encode those in your QR code
