WiFi QR Generator

What this tool does

A WiFi QR generator turns your network name and password into a QR code that connects a phone to the network with a single scan. Instead of reading a long, case-sensitive password aloud or watching a guest mistype it three times, you let them point a camera at a small printed square. The phone reads the network name, the password and the security type, and offers to join — no typing at all.

This tool builds the WIFI: payload that phones recognise, formats it correctly, escapes any special characters in your SSID or password, and renders the code live as you type. Everything is computed in your browser, so the password you enter is never uploaded.

Why you might need it

Sharing WiFi is one of the small, constant frictions of hosting people. A café wants customers online without staff repeating the password all day. A restaurant wants diners connected the moment they sit down. An office wants visitors and new hires onboarded without IT involvement. An Airbnb or guest-room host wants arrivals settled in without a phone call.

A printed WiFi QR code solves all of these at once. It is faster than speaking, it removes mistakes, and it looks professional on a table card or a framed sign. Because the code encodes the network type and the hidden-network flag too, it also handles the cases that confuse people most — a guest network with a long random password, or an SSID that is not broadcast.

How to use it

1. Enter your network name (SSID) exactly as it appears, including capitalisation.
2. Choose the encryption type your router uses — WPA2 for most networks.
3. Type the password. It is used only to build the code, on your device.
4. Tick Hidden network if your SSID is not broadcast.
5. Adjust the size, error correction and colours, then download the code as a PNG for screens or an SVG for print.

The preview updates as you type, so you can see the finished code immediately.

Where to put a WiFi QR code

A few placements work especially well. On restaurant and café tables, a small card next to the menu gets diners online before they have ordered. At a reception desk or guest sign, a framed code welcomes visitors without involving staff. In an Airbnb or guest room, a code in the welcome binder or on the fridge answers the first question every guest asks. For office onboarding, a code on the guest-network poster lets contractors and new starters connect themselves.

For anything visitors use, generate a code for your guest network rather than your main one — it keeps your primary devices separated from traffic you do not control.

Tips for a code that always connects

Contrast is what makes a QR code scannable: keep a dark code on a light background and avoid low-contrast colour schemes, which many older cameras fail to read. Leave the quiet zone — the margin of empty space around the code — clear; this tool adds it automatically, so do not crop right to the edge when you place the code in a design.

If the code will be displayed somewhere it might get scuffed, faded or partly covered, raise the error-correction level to Q or H so it still reads with some damage. Always test the finished code with a real phone before printing a batch, and because the whole payload is assembled on your device, it is genuinely safe to encode your actual network password here — none of it ever leaves your browser.
