FAQ
Is my data sent to a server?
No. All QR code generation happens entirely in your browser. WiFi passwords, contact details and URLs never leave your device.
Can I add a logo to the QR code?
Yes. Upload a PNG or SVG logo and it will be placed in the center of the QR code. The error correction level is automatically set to High so the code remains scannable.
What is the maximum logo size?
Keep the logo within 25% of the QR code width for reliable scanning. The slider enforces this limit.
Why does the QR code look bigger when I add a logo?
Adding a logo forces High error correction, which adds more data modules to the QR code — making it slightly denser so it can still be read even with part of the image covered.
Can I download a high-resolution version for print?
Yes. Choose 2000 px PNG or SVG (infinitely scalable) in the Advanced tab before downloading.
How do I create a QR code with my logo for free?
Upload a PNG or SVG logo in the Logo tab. Error correction is automatically set to High so the code stays scannable even with the logo in the center. No signup, no cost.
