How to Create and Use a QR Code
A QR code turns supplied content or a link into a pattern that a phone can read. Choose the content type first, then decide whether that content must be editable after printing.
Choose static or dynamic content
Static codes store the content directly. They suit Wi-Fi details, plain text, offline contacts and fixed URLs. Dynamic website codes store a link to this platform and let you change the saved destination later. The domain, hosting and record must remain active.
Build a digital contact page
Choose Digital business card, enter the name, company, phone and email, and upload the original card image if you want it shown. JPG, PNG and WebP up to 2 MB are supported. Save the page before downloading the final QR. Visitors can use the contact buttons without an account.
Test your printed design
- Use dark modules on a light background.
- Keep the blank margin and the center logo small.
- Export SVG for scalable print or PNG for digital use.
- Scan the final file and a sample at its actual printed size.
- Test after changing a destination or moving a domain.
Understand linked services
PDF, media, menu, form, payment and ticket tools currently link to an existing resource. A QR that points to a payment page does not itself process the payment. A ticket link does not validate entry on this platform.
Keep printed links working during migration
Redirect each old QR URL to its matching new URL, retaining its path and query. Keep the old domain and HTTPS for as long as those printed materials remain in use.
