Error Correction Levels
QR codes support four levels of error correction, allowing the code to be readable even if partially damaged or obscured. Higher levels provide more redundancy but result in denser codes.
| Level | Recovery | Best For |
|---|---|---|
| Low (L) | ~7% | Clean environments, maximum data capacity |
| Medium (M) | ~15% | General use, good balance |
| Quartile (Q) | ~25% | Harsh environments, logos/overlays |
| High (H) | ~30% | Maximum durability, small logos |
