Open GeneratorFrequently Asked Questions
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.
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.
Is my data safe?
Yes. QR codes are generated entirely in your browser using JavaScript. Your data is never sent to any server. We cannot see what you encode.
Which download format should I choose?
SVG for print (infinite scalability), PNG for digital use and social media, JPEG for smaller file sizes. SVG is the safest choice for most use cases.
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.
