To be sure that your QR Codes are readable, do not print them in less than 3cm square (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 from the Silver plan, you have access to QR Code in high-resolution: (vector-based graphic: 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 through the generator will stop working after being scanned a hundred times. HD QR codes are valid forever, no matter how many times they are scanned, and 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 a logo, change the colours or the shape to customise your QR Codes in an instant. Still, several golden rules cannot be ignored to ensure your design QR Codes remain readable by your consumers. Two topics have to be considered when designing your QR Code:
Contrast between light and dark areas must be strong enough.
By integrating a logo, please ensure the logo does not cover the eyes of your QR Code.
QR Code updates are possible for Dynamic URL QR Codes, and if you subscribe to our Live account. By creating dynamic editable QR Codes, you can edit the QR Codes' content (URLs) in real-time, and see their analytics.

To read a QR code, only two steps are needed:
Open an application and point the camera of your mobile phone at the QR Code
The application then recognises the QR code and performs the associated action, usually accessing a website.
No, a QR code cannot be hacked. This is not possible, since this is the way the small square modules are arranged that determines this action (the module arrangement encodes the data) ; but QR codes can be used maliciously.

An HD QR Code will be sent in a PNG format, size 1200*1200px. This is the best format for printing a QR Code. More formats (SVG vector, PDF, JPEG) are available on our platform starting with the Silver plan.
