How to create a QR code

A QR code turns a link, a bit of text, or a Wi-Fi login into something a phone camera can open in a second. This guide shows what you can encode, how to keep it reliably scannable, and the handy Wi-Fi trick.

The fastest way

Type or paste your link into the QR Code Generator and download the code as an image. Read on to make sure it actually scans.

What you can encode

Most QR codes hold a URL, but they can also carry plain text, a phone number, an email, contact details, or Wi-Fi credentials. The content is baked right into the pattern — a static code has no server behind it and never expires.

Keeping it scannable

• Dark code on a light background — contrast matters.
• Leave a clear quiet margin around the edges.
• Don't print it too small for the distance people scan from.
• Test with a real phone before committing it to print.

The Wi-Fi guest trick

Instead of reading out your Wi-Fi password, print a QR code that connects guests automatically. The Wi-Fi QR Card builds a printable card from your network name and password — a tidy touch for a home or café.

Reading codes back

To check what a code contains or decode one you've been handed, use the QR Scanner.

A note on privacy

The QR Code Generator encodes your content in your browser, so links and Wi-Fi passwords are never uploaded to a server.
