How a logo fits in a QR code
QR codes repeat part of their data as error correction. When you add a logo, the generator switches to the highest level (H, 30%) and caps the logo at 30% of the code's width, so the hidden modules can be rebuilt by the phone. You can also clear the modules behind the logo and put it on a plate.
Your colours, your shapes
Choose the colour of the modules and the background, square, rounded or dotted modules, the shape of the three eyes, and a frame with a short call to action such as "Scan the menu". The generator warns you when the contrast is too low for phones to read it.
Ready for print and screens
Download it as SVG or PDF for print, where it stays sharp at any size, or as PNG for a website or a slide. The design can be saved with a dynamic code and reused for the next ones.
