How to Generate a QR Code for Your Link, Wi-Fi, or Business

26 October 2026 6 min read

QR codes put your menu, shop, Wi-Fi password, or portfolio one camera-scan away. Here is how to make one that scans reliably — and the mistakes that make codes fail.

Point a phone camera at a QR code and it opens a link, joins Wi-Fi, or saves a contact — no typing, no spelling mistakes. That is why they are everywhere: menus, shop windows, business cards, event posters, and product packaging.

Generate a QR code in 3 steps

  • Open the QR Code Generator and type or paste your link or text.
  • Download the QR code image (PNG).
  • Test it with your own phone camera before you publish or print it.

Where QR codes work best

  • Shop windows and packaging: link to your menu, catalog, or WhatsApp.
  • Business cards: link to your portfolio or booking page instead of cramming details.
  • Events: link to the schedule, feedback form, or photo gallery.
  • Wi-Fi: print a code so guests join without asking for the password.

Always test before printing. Scan from the distance people will actually stand at, in normal light. A code that only scans from 10 cm away is useless on a poster.

Mistakes that break QR codes

  • Printing too small — tiny codes on a distant poster will not scan.
  • Low contrast — a light code on a light background fails; dark on light works best.
  • Covering the corners — the three square markers in the corners are how cameras find the code. Never cover them with a logo.
  • Overloading it — very long links create dense patterns that are slow and hard to scan. Use a short link.

Keep it simple, keep it high-contrast, and always test with a real phone. A QR code done right feels like magic; one done wrong just frustrates people.

Frequently Asked Questions

Do QR codes expire?

A plain QR code that encodes a link or text never expires — the pattern itself has no expiry date. What can break is the destination: if you change or delete the linked page, the code stops being useful.

Can I print a QR code on a flyer or menu?

Yes. Download it as a PNG, place it at a decent size (at least 2–3 cm across for short links), and test it with your phone camera from a normal reading distance before printing hundreds of copies.

What can I put in a QR code besides a link?

Plain text, a phone number, an email address, and Wi-Fi credentials are all common. Keep the content short — shorter content makes a simpler pattern that scans faster and from farther away.
