Make a Wi-Fi QR code

Guests point their camera at it and join your network, without you reading out the password.

Make a QR code that joins your Wi-Fi when guests scan it. Your network password is turned into a code on this page and never sent anywhere. It is free, and what you type is not uploaded: everything runs in your browser on your device. The codes are static, so they never expire, and after one visit and a short wait the page works offline.

    A Wi-Fi QR code holds your network name, password and security type in the format phone cameras understand. Scanning it on an iPhone or Android phone shows a “Join network” prompt, so guests, customers and Airbnb visitors connect in one tap.

    Typing your Wi-Fi password into a website is exactly what you should be wary of, and most QR sites do send it to their server. This page builds the code in your browser: the password never leaves your device, and after one visit and a short wait the page works with your internet switched off.

    Print it for a guest room, a café table or a rental welcome book. If you change the password, make a new code; the old one stops joining.

    How it works

    1. Type the network name exactly as it appears (it is case-sensitive) and the password.
    2. Leave security on WPA unless your router is very old, and tick Hidden network only if your network does not broadcast its name.
    3. Scan the preview with your phone to check it joins, then download a PNG or an SVG to print.

    In your browser, not on a server

    A QR encoder written for this site (byte mode, versions 1 to 40, Reed–Solomon error correction and the standard’s mask scoring) turns your text into the grid of squares in your tab. The PNG is drawn on a canvas by your browser and the SVG is written as one path, so both are exact, with no blur.

    Compared with upload-based tools: Most QR code sites make you sign up, send your link and Wi-Fi password to their servers, and hand out “dynamic” codes that redirect through their domain, so they can count scans and switch your code off when a trial ends. Here the code holds your text directly, never expires, and nothing you type leaves your device.

    Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.

    Questions

    Which phones can scan a Wi-Fi QR code?

    Every iPhone since iOS 11 and almost every Android phone since 2018, straight from the camera app. Older Android phones can use Google Lens.

    My phone does not offer to join. What is wrong?

    Usually the network name: it must match exactly, including capitals and spaces. Also check the security type; WPA covers WPA2 and WPA3. A 5 GHz-only network will not join from a phone that cannot use 5 GHz.

    Is it safe to put my Wi-Fi password in a QR code?

    It is as safe as writing the password on a card: anyone who scans it can read it. For a public place, use a separate guest network, which most routers can create, and put that in the code.
