3d QR Code
3d QR Code: this page explains what it means for a QR code and why it is worth understanding before you generate one.
The Short Version
3d QR Code matters at the point where design choice meets scan reliability. The section below covers the specific detail and how to apply it.
When It Matters Most
This becomes relevant the moment a code is going to be scanned by people you have not met, in conditions you do not control, so the margin for error (size, contrast, content length) is worth getting right up front.

Open GeneratorFrequently Asked Questions
Is the 3d QR Code generator free?
Yes, completely free with no sign-up, no watermark, and no limits. Generate as many QR codes as you need.
Can I change the colours of my QR code?
Yes. Use the customisation options to change the dot colour, background colour, dot shape, and corner shape. Ensure sufficient contrast for reliable scanning.
Do QR codes created here expire?
No. Our QR codes are static: the data is encoded directly in the code. They work as long as the linked content exists.
Can I add my logo to the QR code?
Yes. Use the customisation panel to upload a logo image. It appears in the centre of the QR code. Error correction is automatically increased to maintain scanability.
What is the best size for printing a QR code?
Minimum 2cm x 2cm (about 0.8 inches) for close-range scanning. For posters or signs viewed from a distance, increase the size proportionally. A rough rule: 1cm of QR code for every 10cm of scanning distance.
