Open GeneratorFrequently Asked Questions
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.
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.
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.
