Wi-Fi QR code generator
Guests scan, their phone joins your network. No spelling out the password, no typos, no “is that a zero or an O?”.
Phones that scan the code join the network — nobody has to type the password. The network name is case-sensitive.
Static code: it never expires and has no scan limit. Generated in your browser — nothing is uploaded.

PNG, JPG, WebP or SVG. It stays on your device, and the code switches to the highest error correction so it still scans.
How Wi-Fi QR codes work
A Wi-Fi QR code stores your network name, password and security type in a standard format that phone cameras recognise. When someone scans it, their phone offers to join the network — iPhones have done this from the camera app since iOS 11, and so do most Android phones, either from the camera or from a QR icon in the Wi-Fi settings.
The password sits inside the code itself, not on a server. That is what makes the code free forever, and it also means anyone who can see the code can join the network — so display it where your guests are, not in a window facing the street.
Setting it up for an event
Type the network name exactly as it appears in your phone's Wi-Fi list: it is case-sensitive, and a stray space counts. Choose WPA/WPA2/WPA3 for virtually every router made in the last fifteen years, WEP only for very old equipment, and No password for an open network. Turn on Hidden network only if your network does not broadcast its name.
At a venue, put a small card on each table or next to the entrance, with the network name written underneath for laptops and older phones that cannot scan. If the password changes, the code has to be generated and printed again.
Wi-Fi and photo uploads go together
At weddings and conferences, the Wi-Fi card and the photo-sharing card often end up side by side on the table, and for good reason: a video uploads in seconds on venue Wi-Fi and in minutes on a weak mobile signal. If you are collecting your guests' photos, put both codes on one card — one to join the network, one to open your upload page.
Common questions
Do guests need an app to scan a Wi-Fi QR code?
+
No. The built-in camera reads Wi-Fi codes on iPhone (iOS 11 and later) and on most Android phones; on some Android models the scanner sits in Settings > Wi-Fi, behind a small QR icon.
Is it safe to put my Wi-Fi password in a QR code?
+
The password is stored in plain text inside the code, so anyone who scans it can read it and join. Use a guest network for events, rather than the network your computers and cameras are on.
Which security type should I choose?
+
WPA/WPA2/WPA3 for nearly every router in use today. WEP only if your router is very old, and No password for an open network.
What if my network is hidden?
+
Turn on Hidden network. The code then tells phones to look for the network even though it does not broadcast its name.
Does the code expire?
+
No. It keeps working until you change the network name or the password.
Why doesn't my phone offer to join?
+
Check that the network name matches exactly, capitals and spaces included, and that the security type is right. Then check the phone is in range: a code for the venue's Wi-Fi scanned at home has nothing to connect to.
