WiFi QR Code Generator (Free)

1. 1

   Enter the network name

   Type the network name (SSID) exactly as it appears in your phone’s WiFi list, including capitals and spaces.

2. 2

   Choose the security and enter the password

   Most networks use WPA, WPA2 or WPA3. Type the password exactly; it’s shown as you type so you can check it.

3. 3

   Check the preview

   Open “What’s inside this code” to see the network details the code holds.

4. 4

   Style it and download it

   Add colors or a logo if you like, then download a PNG or an SVG.

5. 5

   Test it

   Forget the network on your phone, then scan the code and check it joins. Do this before you print.

A WiFi QR code holds one short line of text in a format phones understand. iPhones (iOS 11 and later) and Android phones (Android 10 and later) read it with the camera and offer to join the network.

WIFI:T:WPA;S:Corner Cafe Guest;P:espresso2024;;

WIFI:

tells the phone this is a network to join

T:WPA

the security type: WPA (also used for WPA2 and WPA3), WEP, or nopass for an open network

S:

the network name (SSID)

P:

the password

H:true

added only for a hidden network

The characters \ ; , : and " have special meaning in this format, so the generator puts a backslash in front of them: a password like pass;word is stored as pass\;word, and the phone reads it back correctly.

For WiFi QR codes

• Write the network name next to the code (for example “WiFi: Corner Cafe Guest”) so people know what it is and can join by hand if their phone can’t scan.
• Use a separate guest network if your router has one, so visitors don’t join the network your own devices use.
• If you change the password, the code stops working. Make a new code and replace the printed copies.

For any printed QR code

• Size: print the code at least 2 cm (0.8 in) wide for something held in the hand. For signs and posters, make it about a tenth of the scanning distance: roughly 10 cm (4 in) wide to scan from 1 m (3 ft).
• Contrast: use a dark code on a light background. Light-on-dark codes and pale brand colors fail on some phones.
• Quiet zone: keep a blank border of at least 4 modules (the code’s small squares) around it. Don’t crop it or put text and graphics right up against the code.
• File type: use the SVG for print, since it stays sharp at any size. The 2048 px PNG is enough for print up to about 17 cm (6.8 in) wide at 300 dpi.
• Surface: avoid glare from glossy laminate, tight curves (bottles, cups) and folds that cut through the code.
• Test: scan a printed proof with an iPhone and an Android phone, at the real distance and in the real lighting, before you print in bulk.

A WiFi QR code works because the phone reads the network name and password straight from the code, so it can’t be a dynamic code that redirects somewhere. That’s also why it never expires: there’s no server in between. If you change your password, make a new code.

If your password changes often, or you want the WiFi details next to other information like check-in times and house rules, use a hosted page instead: a dynamic code opens a page showing the network name and password with copy buttons, and you update the page rather than reprinting the sign. CirculateQR’s Airbnb check-in template is built for this. The trade-off is that guests copy the password rather than joining in one tap.

The code you make on this page is static: free, permanent and private, but fixed once printed. Static and dynamic codes compared.
