Error Correction Levels
QR codes include built-in error correction that allows them to be scanned even when partially damaged or obscured:
| Level | Recovery | Best For |
|---|---|---|
| L (Low) | ~7% | Clean digital displays, maximum data capacity |
| M (Medium) | ~15% | General purpose use, good balance |
| Q (Quartile) | ~25% | Printed materials that may get dirty |
| H (High) | ~30% | Industrial use, adding logos (with caution) |
Logo Embedding
Add your company logo or custom image to the center of QR codes for brand recognition:
- Automatic Error Correction: When adding a logo, we automatically set High (H) error correction level, which allows up to 30% of the QR code to be obscured while remaining scannable.
- Customizable Size: Adjust logo size from 10% to 40% of the QR code — larger logos look better but reduce scannability.
- Shape Options: Choose square, rounded, or circular logo shapes to match your brand style.
- Background Padding: Add a white (or custom color) background behind your logo for better contrast against the QR pattern.
- Test Thoroughly: Always test QR codes with logos on multiple devices before printing, as logo placement affects scannability.
Tips for Better QR Codes
- Size matters: For print, use at least 2cm × 2cm (0.8" × 0.8"). The scanning distance is roughly 10× the QR code size.
- Contrast is key: Dark foreground on light background works best. Avoid low-contrast color combinations.
- Test before printing: Always test your QR code with multiple devices before mass printing.
- Keep it simple: Shorter URLs create smaller, easier-to-scan QR codes. Consider using URL shorteners for long links.
- Higher resolution for print: Use 4x resolution (1000×1000px for 250px display size) for high-quality printing.
- Logo best practices: Keep logos at 20-25% size for best balance between branding and scannability.
