A logo in the centre of a QR code looks professional and measurably raises scan conversion compared to plain black-and-white codes (+15 to +30 % in typical marketing A/B tests).
How it works
QR codes have built-in error correction (Reed-Solomon). Up to ~30 % of the matrix can be damaged before the code becomes unreadable. We reserve space in the centre — your logo overlays it and the error correction covers the rest.
Steps
- Scroll to the Logo overlay section in the editor.
- Choose file — PNG, JPEG or SVG up to 2 MB.
- The logo appears next to the button. You can clear it via Remove any time.
- Create code — the logo is centred automatically at render time.
What makes a good logo
- Square or round — portrait or landscape proportions look off-balance
- Strong contrast to the QR foreground colour
- Transparent background for PNG/SVG — otherwise you get a white block behind the logo
- No fine detail at the edge — we soft-clip logos into the code, delicate edges get lost
Warning: contrast
The single most common failure: a logo in a colour too close to the QR foreground. If your code is dark blue, pick a white or light-grey logo — not a second blue.
Always test with a phone camera before printing. If the code does not scan in 1 second, shrink the logo or raise the contrast.
