Wi-Fi QR code generator
Create a QR code that connects guests to your Wi-Fi network — no password typing. Free PNG and SVG downloads.
There's an API for this — free, no key
Everything this generator does is also one GET request away. Build any QR code above, press API, and you get a shareable URL that renders the exact same design — PNG or SVG, any size up to 2048px, all dot styles, marker shapes, and colors.

A Wi-Fi QR code lets guests join your network by scanning — no spelling out passwords, no typing on tiny keyboards. Enter the network name, password, and security type, and print it for cafés, offices, waiting rooms, rentals, and events. Frame it on the table and you are done.
What a Wi-Fi QR code encodes
The code holds a standard WIFI: string with your network name (SSID), password, and security type (usually WPA/WPA2). It is a recognised format every modern phone understands natively. The credentials are encoded in the pattern itself — nothing is stored on our servers — so the code works forever, entirely offline, with no app in between.
What happens when someone scans it
Both iPhone and Android offer to join the network straight from the built-in camera — the phone reads the code, shows a Join "NetworkName" prompt, and connects on tap. There is nothing to install and nothing to type. For a guest, connecting drops from spelling out a 20-character password to a single scan.
A note on password safety
Be deliberate about where you post it. The password is encoded in the pattern in readable form — anyone who can scan the code can join, which is exactly the point for guest Wi-Fi, but means the code is as sensitive as the password itself. Put it only where the right people see it, use a separate guest network where you can, and generate a fresh code whenever you rotate the password.
Print it to last
Guest Wi-Fi codes live on tables and walls, so print an SVG that stays sharp and laminate or frame it. Keep strong contrast and a clear margin. Many venues pair the Wi-Fi code with a second QR code — a short link to the menu, a review page, or an offer — so the same table tent both connects guests and drives a tracked action. See table-tent ideas on the blog.
Guest Wi-Fi done properly
The safest way to share Wi-Fi by QR code is to share a network you do not mind being on a wall. Put guests on a separate guest SSID rather than your main network, so a scannable password never exposes internal devices, and rotate that password on a schedule — regenerating the code takes seconds. If your router supports client isolation on the guest network, turn it on so scanned-in devices cannot see each other.
For venues, the Wi-Fi code rarely travels alone. Many pair it on the same table tent with a second QR code — a trackable short link to the menu, a review page, or an offer — so connecting a guest and prompting a measurable action happen in one glance. Print the pair as an SVG so both stay crisp, laminate them, and you have a table card that earns its place.
Other QR code types
Need a different kind of code? Try the vCard QR code and URL QR code. Any code here can become a dynamic QR code you edit after printing and track on every scan — and if you just need a short link, the URL shortener counts every click.
