M suits most prints. Choose Q or H for signs that may get scuffed or wet.

How to make a QR code for your Wi-Fi

  1. Copy the network name exactly. Open your phone's Wi-Fi list or the sticker on the router. "Cafe-Guest" and "cafe guest" are different networks.
  2. Pick the security type. Nearly every home and café router uses WPA2 or WPA3; leave the default unless you know otherwise.
  3. Type the password and check the preview. The card on the right redraws on every keystroke. Errors (too short, too long) show up under the fields.
  4. Test it with your own phone before you print, then download a PNG for messages or an SVG for sharp printing at any size.

What is inside the code

A Wi-Fi QR code is just a short line of text that phone cameras recognise. For the preview above it currently reads:

WIFI:T:WPA;S:Your network;P:••••••••;;

T is the security type, S the network name, P the password and H:true marks a hidden network. Characters such as ; and : in a name or password get a backslash in front so the phone doesn't misread them. The format guide has the full rules.

Why a long password makes a denser code

Each character of the name and password takes up space in the pattern. When the text outgrows the current grid, the QR standard (ISO/IEC 18004) steps up to the next version, adding four modules per side. Drag the sliders to see how length, error correction and scanning distance decide how big you should print.

The 10:1 distance-to-width rule is a common printing guideline, not a hard limit; good light and a flat surface help more than extra size.

Where Wi-Fi QR codes help

Holiday rentals. A framed card by the door answers the first question every guest asks. Hosts on Airbnb and Vrbo often add one to the welcome book as well.

Cafés and restaurants. A table tent beats reading a 16-character password off a chalkboard. Put a guest network on it, not the one your card machine uses.

Offices and events. Print a code on badges or the reception desk. Rotating the guest password? Generate a new code the same morning.

At home. Tape one inside a kitchen cupboard so visiting family can join without hunting for the router sticker.

Keep it safe

Anyone who scans the code can read the password, and the password is printed in plain text inside it. So:

  • Share a guest network rather than your main one, if your router supports it.
  • Change the guest password now and then, and print a fresh code.
  • Don't post a photo of the code online.

Questions

Is my Wi-Fi password sent anywhere?

No. The QR code is drawn by JavaScript in your browser. The network name and password are never sent to our server, never sent to an AI model and never logged. They are only saved on your device if you tick "Remember on this device", and you can clear that at any time.

Do iPhones and Android phones scan Wi-Fi QR codes without an app?

Yes. The iPhone Camera app has read Wi-Fi codes since iOS 11 (2017). Android phones read them in the camera app or Google Lens on almost every model sold since Android 10 (2019).

Which security type should I choose?

Pick "WPA / WPA2 / WPA3" for almost every router made in the last 15 years, including mixed WPA2/WPA3 routers. Choose "WPA3 only" when your router is set to WPA3-only (SAE). Use WEP only for very old equipment and "No password" for open networks.

Will the QR code stop working?

No. A Wi-Fi QR code is static: the network name and password are written into the pattern itself and it never expires. If you change the password or rename the network, make a new code.

Why does the code look denser with a long password?

Every character is stored in the pattern, so a longer password or network name needs more squares. Print the code a little larger if your password is long; the explainer on this page shows how much.

What is the hidden network option?

It adds H:true to the code so phones know to look for a network that does not broadcast its name. Only tick it if your network really is hidden, otherwise some Android phones take longer to connect.
