Error correction codes allow the QR code to be scanned accurately even if partially damaged. Levels include:

• L (Low): Recovers 7% of code

• M (Medium): Recovers 15%

• Q (Quartile): Recovers 25%

• H (High): Recovers 30%

4. Visual Rendering

The QR code is rendered into an image format (PNG, SVG) with optional customization (colors, logos, size).
