How to create a QR code
Updated 2026-08-25
QR codes turn a string of data into a pattern phones can scan.
QR Code Generator on A2Z Edit builds codes in your browser for URLs, text, Wi‑Fi, and other content types.
How to create a QR code
- Open QR Code Generator on A2Z Edit.
- Choose the content type (text/URL, Wi‑Fi, email, phone, and similar options).
- Fill in the fields for that type.
- Customize colors or style if you want, then generate the code.
- Download the QR image and test it with your phone camera.
Why it matters
A scannable code beats typing long URLs on a phone keypad.
Tips
- Keep URLs short when you can—dense codes are harder to scan from far away.
- Ensure strong contrast between dark modules and a light background.
- Print a test copy at the real size before a big batch.
