Create a QR code in 3 steps

- Enter your content and customize colors, shapes, and your logo.
- Download a high-resolution PNG/SVG file and start using it.
Recover a lost dynamic QR code
- Sign up or log in, then open the QR code manager.
- Create a dynamic QR code and enable the old dynamic code ID option.
- Enter the old code ID (scan your printed QR code to see the ID string at the end of the link).
- Save — your printed QR code keeps working with the new content.
Tips for reliable scanning
- Keep strong contrast between the code and its background.
- Print at least 2x2 cm for close-range scanning, larger for posters.
- Always test-scan on a few devices before printing at scale.
