Do I need to create an account to generate a QR code?
No. Choose your content, customize your QR code and download it for free, no registration required.
Which format should I choose: SVG or PNG?
SVG stays sharp as you enlarge it: it's ideal for print and layout tools. PNG is an easy-to-use image for web and documents. Its size can be adjusted in advanced options.
Can I change the content of a QR code that's already printed?
The content is directly encoded in the QR code: it can't be changed after creation. For a web link, you can update the destination page while keeping the same address. A new address requires a new QR code.
How do I check that my QR code works?
Scan it with your phone before sharing, then test it on the final medium. Use a light background, contrasting patterns, and leave a clear margin around the code. An oversized logo or similar colors may affect scanning.
