About this QR code generator
This tool builds a standard QR code from whatever you enter — a web address, plain text, Wi-Fi credentials, or a contact card — and renders it directly in your browser. Once generated, download it as a PNG to print, share, or embed anywhere.
What can I encode?
- URL — links straight to a website when scanned.
- Text — any plain message, up to a few thousand characters.
- Wi-Fi — lets a phone join a network automatically after scanning.
- Contact — a basic vCard that a phone can save straight to contacts.
Frequently asked questions
Do the QR codes expire?
No. A QR code is just a pattern encoding your text — it works for as long as the content it points to (like a URL) stays valid.
Is my data uploaded to a server?
No. The QR code is generated entirely in your browser using JavaScript, so nothing you type leaves your device.
What size should I use for printing?
For most printed materials, 300×300px or larger keeps the code easy to scan from a normal reading distance.
