A QR code with a logo strengthens your brand identity and builds trust. QR codes include error correction that tolerates up to 30 per cent of the surface being obscured.
Understanding error correction
Four levels exist: L (7%), M (15%), Q (25%) and H (30%). Use level H for logos. You can place a logo covering roughly 20 per cent of the total surface.
Design rules
Centre your logo and surround it with a white buffer zone. Use a simple, high-contrast logo. Square or circular logos work better than wide rectangular ones.
Step-by-step creation
Generate your code at level H. Export in SVG. In a graphic editor, place your logo in the centre at no more than 20 per cent of the surface with a white background.
Common mistakes to avoid
Never cover the three finder patterns in the corners. Do not use a transparent logo without a white background.
