Putting a logo into the center can look premium — but only if you keep the QR structure readable.
Keep the logo small
Aim for a modest center logo. If it covers too much of the QR modules, scanning becomes unreliable.
Use a clean background under the logo
Place the logo on a solid shape (usually white) so the QR modules around it stay high-contrast.
Don’t touch finder patterns
The three big corner squares are sacred. Keep them intact and high-contrast.
Test on real devices
Scan with 2–3 phones and from different angles. If any device struggles, reduce logo size.
