Style

Strong keeps the code scannable with up to about a third of it scuffed, dirty or covered, but makes the pattern denser. Standard suits most uses.

Enter your network name and your QR code appears here.

Download

PNG suits documents, slides and websites.

Print a sheet

Each label is about 9.3 × 9.0 cm. Print at 100% scale (turn off “fit to page”). To save a PDF instead, choose “Save as PDF” as the printer.

How to make a Wi-Fi QR code

  1. Type your network name exactly as it appears on your devices. Capitals and spaces count.
  2. Choose the security type. For almost every router, that’s WPA / WPA2 / WPA3.
  3. Type the Wi-Fi password, then scan the code with your own phone to check it joins.
  4. Add a label such as “Scan to join our Wi-Fi”, and print or download it.

Where to find your network name and password

  • On the router: most have a sticker with the network name and password, unless someone has changed them since.
  • On an iPhone that’s connected: open Settings, then Wi-Fi, tap the ⓘ next to the network, and tap Password.
  • On an Android phone that’s connected: open the Wi-Fi settings, tap the network, then Share. Many phones show the password under their own QR code there.
  • In your router’s settings page: the address and login are usually on the same sticker.

Making a Wi-Fi sign for guests

  • For a café, office or holiday let, give guests a guest network if your router has one. It keeps visitors off the network your own computers and printers are on.
  • Print one large code for a wall, or 4 or 6 per page to cut out for tables and rooms.
  • Write the network name somewhere near the code too, for anyone whose phone won’t scan.
  • Remember the password can be read from the code. If you share a network you’d rather keep private, change its password afterwards and make a new code.

Need a different kind of code? The full QR code generator also makes codes for links, text, email and SMS, and there’s a contact card QR code generator for business cards.

Frequently asked questions

Does a Wi-Fi QR code work on iPhone and Android?

Yes. On iPhone, point the Camera app at the code and tap the “Join network” prompt. Most Android phones do the same from the camera, or from Google Lens on older models. Nobody has to type the password.

Is my Wi-Fi password sent anywhere?

No. The code is drawn in your browser and nothing you type is sent to us or anyone else. The password is stored inside the printed code, though, so anyone who scans it can read it.

What happens if I change my Wi-Fi password?

The old code stops working, because the password is part of the pattern. Make a new code with the new password and reprint it.

Which security type should I pick?

Almost always WPA / WPA2 / WPA3, which covers nearly every home and business router. Choose WEP only for very old equipment, and None only for open networks with no password.

Does it work with WPA3?

Choose WPA / WPA2 / WPA3. Most routers run WPA2 and WPA3 together, and phones join those fine. A network set to WPA3 only may not join from some older phones, which can’t use WPA3 at all.

Does a Wi-Fi QR code expire?

No. It’s a static code: the network details are stored in the code itself, not on a server, so it works for as long as your network name and password stay the same.
