QR Code Generator

Links, Wi-Fi, WhatsApp and contact cards as QR.

Make QR codes for a website link, plain text, phone number, email, Wi-Fi network, WhatsApp chat or contact card. Download PNG for everyday use or SVG for print at any size. No account and no expiry — these are static codes that work forever.

How to use

  1. Choose what the QR code should contain.
  2. Fill in the details; the code updates as you type.
  3. Optionally change size, colour, error correction or add a small logo.
  4. Download PNG or SVG, and test it with your phone camera before printing.

Static vs dynamic QR codes

ZIYNU creates static QR codes: the information is stored in the pattern itself, so the code never expires and doesn't depend on any service staying online. Dynamic codes from subscription services point to a redirect link that can be changed later — and stop working if the subscription ends.

Tips for codes that scan

Keep strong contrast — dark code on a light background. Leave the white margin (quiet zone) around the code. Printed codes should be at least 2 cm wide, and larger when scanned from a distance. Shorter content produces a simpler pattern that scans more easily.

Good to know

  • Wi-Fi codes contain your network password in readable form — only share them with people you'd give the password to.
  • Adding a logo raises error correction to High so the code still scans with part of it covered.

Frequently asked questions

Do these QR codes expire?

No. They are static and work for as long as the content (for example, the website) exists.

Should I download PNG or SVG?

PNG is fine for screens and documents. SVG is a vector format that stays sharp at any print size, ideal for posters and packaging.

How do I make a WhatsApp QR code?

Choose WhatsApp, enter the number with country code and no + or spaces (e.g. 923001234567), and optionally a pre-filled message.

Is my information stored?

No. The QR code is generated in your browser and nothing is sent to ZIYNU.
