What is a QR Code and how does it work?
A Quick Response (QR) code is a type of matrix barcode (or two-dimensional barcode) first designed in 1994 for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. In practice, QR codes often contain data for a locator, identifier, or tracker that points to a website or application. Our online QR Code Generator allows business professionals and creators to generate customized QR codes for mobile users.

- Click Upload Custom Logo and select a small image to be painted at the center.

Frequently Asked Questions
Do QR codes expire?
No. The generated QR codes are static, meaning the data is directly encoded into the dot matrix pattern. They will work forever as long as the destination URL remains active.
How do I ensure my QR code is scannable?
Ensure there is high color contrast between the dark foreground and light background. Avoid dark backgrounds with dark foregrounds. Also, do not cover more than 30% of the center area when inserting logos.
