STATIC QR WORKSHOP
Wi-Fi QR Code Generator
Let guests join your Wi-Fi with one scan instead of typing a long password. Enter the network name and password, check the code, and print it for the table, the front desk or the fridge door.

What happens when someone scans it
A Wi-Fi QR code contains a short line of text in a format that phones recognise, for example WIFI:T:WPA;S:Cafe Guest;P:espresso-2026;;. When the camera sees it, the phone shows a prompt such as “Join network Cafe Guest”. One tap and the phone connects, using the password from the code. Nobody has to read a password off a card or ask staff to spell it out.
Most recent iPhones and Android phones read Wi-Fi codes in the built-in camera app. On some Android models the scanner lives in the Wi-Fi settings screen (a small QR icon next to “Add network”) or in Google Lens. If a guest's camera only shows the raw text, that is the place to look.
How to fill in each field
Network name (SSID)
Type the name exactly as it appears in the list of networks on your phone, including capital letters, spaces and punctuation. “Cafe Guest” and “cafe guest” are different networks. The name can be at most 32 bytes long, which is the limit Wi-Fi itself sets.
Security
Choose WPA / WPA2 / WPA3 for almost every home and business router made in the last fifteen years — the code format uses the same “WPA” value for all three. Choose WEP only for very old equipment; WEP is broken and you should upgrade the router if you can. Choose None for an open network without a password.
Password
WPA passwords are 8 to 63 characters long (or exactly 64 hexadecimal characters). The form checks this before drawing the code, so a typo like a missing character is caught before you print. Press “Show” next to the field to reveal the password and compare it with the sticker on your router.
Hidden network
Tick this only if your router does not broadcast the network name. It adds H:true to the code so phones know to look for a network that is not in the list.
Special characters are escaped for you
The Wi-Fi format uses semicolons, colons and commas as separators. If your password contains ; , : " they must be preceded by a backslash or the phone will cut the password short. QR Studio adds the escapes automatically and tells you when it did. Open “Encoded content” under the form to see exactly what goes into the code.
Common mistakes
- Changing the password later. The password is printed inside the code. If you change it on the router, every printed code stops working and you need to make and print a new one.
- Separate 2.4 GHz and 5 GHz names. Some routers show two network names. Make the code for the one you want guests on, or one code for each.
- Enterprise networks. Networks that ask for a username as well as a password (WPA2-Enterprise, often found in offices and universities) are not supported by this form.
- Login pages. If your guest network shows a sign-in or terms page after joining, the code still connects the phone, but the guest will see that page next.
- Posting it in public. Anyone with a QR reader can see the password inside the code. Only display it where you would be happy to show the password itself, and consider a separate guest network.
Where Wi-Fi codes work well
Table tents in cafés and restaurants, the reception desk of an office, a framed card in a holiday rental, a waiting room, a classroom whiteboard or the fridge door at home. For printing, download the SVG, add a label such as “Scan to join Wi-Fi” under the code, and test a printed proof with both an iPhone and an Android phone before laminating it.
Questions
Can people see the Wi-Fi password in the code?
Yes. The password is stored as readable text inside the code, so any QR reader app can show it. Treat a printed Wi-Fi code like a printed password and put a guest network on it where possible.
Is my Wi-Fi password sent to your server?
No. The code is made in your browser and nothing you type is uploaded. You can disconnect from the internet after the page has loaded and the generator still works.
Does the code work on iPhone and Android?
Most recent iPhones and Android phones join Wi-Fi from the built-in camera. Some Android phones scan from the Wi-Fi settings screen or Google Lens instead. Test your printed code on the kinds of phones your guests use.
What happens if I change my router password?
The old code stops working because the old password is inside it. Make a new code with the new password and replace the printed copies.
Which security option should I choose?
WPA / WPA2 / WPA3 for nearly all modern routers, None for an open network, and WEP only for very old equipment. The code format uses the same WPA value for WPA, WPA2 and WPA3.
Can I make a code for a hidden network?
Yes. Tick “This is a hidden network” so the code tells phones to look for a network that does not broadcast its name.
