Free Wi-Fi QR code — let guests connect with one scan

How to create a Wi-Fi QR code in 3 steps

1. Open the generator — the “Wi-Fi” mode is already selected if you arrived from this page.
2. Fill in the network: the network name (SSID, the one shown in the Wi-Fi list), the security type and the password.
3. Generate and export: PNG up to 3000 px for printing, vector SVG for a perfect rendering at any size, or a print-ready PDF. A text frame (“Guest Wi-Fi — scan me”) is available to make the code self-explanatory.

The whole thing takes less than a minute. Your credentials never leave your device: generation runs locally in the browser.

WPA, WEP or open network: which should you pick?

The generator offers three security types, matching the Wi-Fi QR code sharing standard:

• WPA/WPA2 — the default choice, and the right one in the vast majority of cases. It also covers WPA3 networks: recent phones interpret the code correctly.
• WEP — only for very old hardware. WEP encryption is obsolete and can be broken in minutes; if your router still offers it, change the setting on the router instead.
• None (nopass) — for an open network with no password: the code connects directly, asking nothing.

If in doubt, check the label on your router or the network settings: reproduce the type shown next to the network name.

Where to use a Wi-Fi QR code?

• Holiday rental / Airbnb: a laminated code on the entrance furniture or slipped into the welcome booklet. No more “what’s the password?” messages at 11 pm — and no need to change it out of caution at every checkout, the guest network stays the same.
• Office and meeting room: display the guest network code in the reception area. Visitors connect without asking the front desk or IT.
• Café, restaurant, salon: on the counter or the tables, next to the menu. Connection becomes self-service, and your team stops dictating the password a hundred times a day.
• Events: a large-format code (the 3000 px PNG is enough for an A3 poster) at the welcome point.

Why this code will never expire

The Wi-Fi QR code is a static code: the network name, security type and password are encoded in the pattern itself, in the standard WIFI: format. There is no redirection through an intermediate server — unlike “free” generators that kill their codes after a few days to push a subscription. The code you print today will still work in ten years. → Static vs dynamic QR codes explained

Good practices and limits to know

• The password is readable by anyone who scans the code — it is written inside the pattern. Display the code where you would display the password: in a guest or customer area, not on the street-facing window.
• If you change the network password, the old code becomes unusable: generate a new one (it is free and instant) and replace the printout.
• Ideally, use a dedicated guest network, separate from your main network — most routers offer one. That way, sharing the code only gives access to the Internet.
• Test the printed code with a real phone before distributing it — and if you use custom colors, check the contrast. → QR codes and color contrast

Frequently asked questions

Does the Wi-Fi QR code work on iPhone and Android?

Yes. The iPhone camera (iOS 11+) and most recent Android devices natively recognize the WIFI: format and offer to join the network in one tap, with no app to install.

Can someone who scans the code see the password?

Yes: the password is written in plain text inside the code’s content — that is what lets the phone connect. Treat a displayed code like a password written on the wall: keep it for people you would give the Wi-Fi to anyway.

What happens if I change the Wi-Fi password?

The existing code stops working, because the password is frozen in the pattern. Simply generate a new QR code with the new password and replace the printed one.

Can I create a QR code for an open network?

Yes: choose “None” in the security type. The code will connect directly, without asking for a password — handy for a captive portal or a public network.

Does the Wi-Fi QR code expire?

Never. It is a static code: the data lives in the pattern, not on a server that could delete it. As long as the network and its password stay the same, the code works.

And how do I scan QR codes I receive?

Use our online QR code scanner: paste an image or use the camera, nothing to install.
