Printable Wi-Fi QR code card

Guests point their phone camera at the code and join your Wi-Fi. Free, no sign-up, and nothing you type leaves your browser. How it works

Enter a network name to make the code.

How it works

Type the network name and password exactly as your router has them. The card and its QR code update as you type.
Check the line under the card. The page reads its own QR code the way a phone would and tells you which network a phone will join, before you print anything.
Print it, or download it. Print at true size, or save a PNG at 300 dpi that keeps its size when you place it in Word or a design tool.

Guests open their phone camera, point it at the code and tap the prompt to join. No app, no typing, and the network name and password are printed underneath for anyone whose camera will not scan.

Four ready-to-print layouts

Card (A6): for a table, a counter or a holiday rental's welcome folder.
Table tent (A5, folded): stands on a café table and reads from both sides.
Poster (A4): one large code for a wall, a window or next to the till, readable from a distance.
Sheet of cards (A4): four cards with cut lines, for printing on an ordinary home or office printer.

Label columns print the same details under different field names side by side, so one card can say "Network" and "Hálózat", in any languages you type.

Private by design

Nothing you type leaves your browser. The card is made entirely on your device, and the page is locked so it cannot send data anywhere except an anonymous visit count. You can check: open your browser's developer tools, go to the Network tab and type, or switch to airplane mode. The page keeps working, and once loaded it also works offline and can be installed as an app.

Questions

Does it work on iPhone and Android?

Yes. The camera apps on current iPhones and Android phones recognise Wi-Fi QR codes and offer to join the network with one tap. Very old phones may need a QR scanner app.

Which security type should I choose?

Choose WPA / WPA2 / WPA3 for almost every router, including routers in mixed WPA2/WPA3 mode. Choose WPA3 only if your router accepts WPA3 alone, None for an open network, and WEP only for very old equipment. Your router's settings page shows which one it uses. Networks that ask each person for their own username and password (enterprise, common at offices and universities) are not supported: phone cameras cannot join them from a code.

The code does not scan. What now?

First check the line under the card: if it names your network, the code itself is right. Then make the code bigger (fewer label columns or a larger layout), print in black on white paper, and make sure the password matches your router exactly. Hidden networks scan less reliably on some phones, and a password ending in a backslash can trip up Android phones; the form warns about both.

Why is the password printed on the card?

Because the card is for a network you mean to share, like a café's guest Wi-Fi. The printed password is the fallback for a camera that will not scan. You can also leave it off: turn off Show password on the card in the Layout section, and the card keeps only the code and the network name. The password stays inside the QR code either way, since that is how phones join. For a private network, set up a guest network on your router and put that on the card instead.

How do I print it on A4 paper?

Choose Sheet of cards: four A6 cards and cut lines on one A4 page. Print at 100% or actual size; "fit to page" shrinks the cards and the codes with them.

Can I edit the card in Word or a design tool?

Yes. Download the PNG: it is 300 dpi and carries its real size, so it lands in Word at true A6. The SVG download stays sharp at any size and embeds its fonts.

Can I keep a card for later or move it to another device?

Your card is saved in this browser automatically. To keep a copy or move it, use Save file, or Copy link and open the link on the other device. Both include the password, since the card exists to share it.

Is it free?

Yes, and it will stay that way. No account, no sign-up, no watermark, and the codes never expire. A Wi-Fi QR code is a short, public set of rules, and following them correctly should not come with a subscription or an advert. Small tools like this should be available to everyone, so I made one and put it here.
