WiFi QR Code Generator

What is a WiFi QR code generator?

A WiFi QR code generator takes your network name and password and packs them into a single QR code using a format phones already understand. Instead of a link or a message, the code holds structured network details, so a phone's camera app recognizes it as WiFi credentials rather than plain text and offers to join on the spot.

That is the whole appeal of a QR code for WiFi: nobody types a fiddly password from a sticky note or reads it out letter by letter. Guests at a house, customers in a shop, or attendees at an event just open their camera, point it at the code, and tap to connect.

How to use it

1. Enter your network name and password. The tool opens straight on the Wi-Fi tab — type the SSID exactly as it broadcasts, add the password, and pick the security type: WPA/WPA2/WPA3, WEP, or none. Tick “hidden network” if your router does not broadcast its name.
2. Set the error correction level and pick a colour. Higher error correction survives scratches and bad lighting but makes a denser pattern; the colour picker changes only the dark squares, since the background stays white for reliable scanning. The live preview updates as you type, showing the code's size in modules.
3. Download it and test before you print. Grab the PNG at 1024 px for a quick sticker or sign, or the SVG if it is going into a poster or card design that gets resized. Scan it with your own phone once before it goes up anywhere permanent.

What to know before you print one

The single most important fact about a WiFi QR code: the password sits inside it as plain text, not encrypted or hashed in any way. Anyone who scans the code — or simply photographs the printed sticker and decodes it later, no scanner needed — gets your actual password. Treat it the way you would treat the password itself: fine for a guest network on a desk or a sign in a holiday rental, but never posted publicly on social media or a website.

On the phone side, this format works with the built-in camera app on iOS 11 and later and Android 10 and later, which recognize it and offer to join immediately; older Android phones may need a separate QR scanner app or the scanner inside their WiFi settings screen. One token covers WPA, WPA2 and WPA3 home networks, but there is no way to express enterprise WiFi — the 802.1X kind that also asks for a username — so this will not work for university or corporate networks.

Punctuation in your network name or password (semicolons, colons, commas, backslashes, quote marks) is escaped automatically, so passwords with special characters scan correctly. And because the code is static, changing your WiFi password does not update any printed copies; you will need to generate and reprint a new one.

Why is it free?

The whole thing runs in your browser — your network name and password are encoded locally and never sent anywhere, so there is no server cost tied to how many codes get made. No account, no watermark on the download, no paid tier hiding a bigger error correction level or a colour option behind it.
