To ensure your QR Codes are readable, do not print them smaller than 3 cm x 3 cm (1.2 x 1.2 inches). You can still choose smaller print sizes for your QR Codes, but you need to be very careful. Please read more advice by clicking on the link below.
Starting with the Silver plan, you can download your QR Code in high resolution (vector-based formats: PDF, SVG, PNG, JPEG up to 3000px). With our free generator, you can download the QR Code in PNG at a size of 300 pixels.
Free QR Codes created with the generator will stop working after 100 scans. HD QR codes are valid forever; no matter how many times they are scanned, they will continue to function indefinitely. QR codes under a subscription are valid, and function depending on the limit of QR codes for the active subscription, and have no scan limit either.
Our powerful QR Code generator lets you create and place a logo, change the colors or the shape to customize your QR Codes in an instant. Still, several golden rules can not be ignored to ensure your custom QR Codes remain readable for your consumers. Two topics have to be considered when designing your QR Code:
Contrast between light and dark areas must be strong enough.
When adding a logo, make sure it does not cover the eyes (corner squares) of the QR Code.
QR Code updates are possible for Dynamic URL QR Codes, and if you subscribe to a Silver account. By creating dynamic editable QR Codes, you can edit the QR Code's content (URLs) in real-time, and see their analytics.

Reading a QR Code requires just two steps:
Open a scanning app and point your smartphone camera at the QR Code.
The application then recognises the QR code and performs the associated action, usually accessing a website.
No, a QR Code itself cannot be hacked. The encoded data is based on the arrangement of the square modules, which cannot be altered remotely. However, QR Codes can still be used maliciously (e.g., to link to harmful websites).
