WiFi QR code generator

Turn a network name and password into a QR code that phones can scan to join the network. Everything is built locally in your browser: the credentials never leave your device, and the finished code works forever without an account or a redirect.

Create a WiFi QR code

WiFi QR code generator: step by step

  1. Open the generator and choose WiFi network as the content type.
  2. Enter the exact network name (SSID) as it appears in the WiFi list. It is case sensitive.
  3. Add the password and select the security type: WPA covers WPA, WPA2 and WPA3, while WEP and open networks have separate options.
  4. Download the SVG for print or the PNG for screens, then test the code with a phone camera before printing a large run.

What is inside a WiFi QR code

A WiFi QR code is plain text written in a format that mobile operating systems already understand: WIFI:T:WPA;S:MyNetwork;P:MyPassword;H:false;;. T is the security type, S is the SSID, P is the password, and H says whether the network is hidden.

Because the credentials are encoded directly in the pattern, this is a static QR code. There is no short link, no account, and no server that can switch it off later. Every person who scans it gets the same network details, and the code keeps working as long as the network name and password stay the same.

Semicolons, commas, colons, backslashes and quotes in an SSID or password have to be escaped or the scanner will misread them. The generator does that automatically, but it is worth knowing if you are comparing tools.

Which security type should you select

Choose WPA for almost every modern router. The QR format uses the same WPA value for WPA, WPA2 and WPA3, so you do not need to work out which generation your router uses.

Choose WEP only for old hardware that cannot be upgraded, and None for an open network with no password. Hidden networks can be encoded with the H field, but many phones are unreliable at joining them from a scan, so broadcasting the SSID is the safer choice.

  • WPA - WPA, WPA2 and WPA3 networks, including most home and office routers
  • WEP - legacy equipment only, not recommended for new networks
  • None - open networks and captive-portal guest networks

Where a WiFi QR code is useful

Print the code wherever someone would otherwise have to ask for the password or type a long string on a phone keyboard. A small sign is enough: the camera does the work.

  • Guest WiFi in cafes, holiday rentals and small offices
  • Conference rooms and shared coworking spaces
  • A framed sign at reception or a table tent
  • A label on the router card for family members and house sitters

Before you print a large batch

Test the finished code with both an iPhone and an Android phone. Current iOS and Android versions offer to join the network straight from the camera app; older devices may need a third-party scanner or manual entry.

Use a dark foreground on a light background with a clear quiet zone around the pattern. Inverted colours, glossy laminates and very small print are the most common reasons a code fails to scan. The generator warns you when the contrast of the chosen colours is too low.

Anyone who can see the sign can read the credentials. For shared spaces, put guests on a separate SSID with client isolation, and reprint the code whenever that password changes.

Frequently asked questions

Do WiFi QR codes work on both iPhone and Android?

Yes. Recent iOS and Android versions recognise the WIFI: format directly from the built-in camera app and show a tap-to-join prompt. Older phones may only display the raw text, in which case the network details are still visible and can be entered manually.

Is my WiFi password stored on your server?

No. The QR pattern is drawn by JavaScript inside your browser and the network details are never transmitted. You can verify this by loading the page, disconnecting from the network, and generating a code: it still works because no request is made.

Can I change the WiFi password without reprinting the code?

Not with a static QR code. The password is part of the pattern, so changing it requires a new code. Dynamic generators can redirect to a new value, but that depends on their server staying online and usually requires a paid account.

Why is my WiFi QR code not recognised by a phone?

The usual causes are a wrong security type, an SSID with mismatched capitalisation, low contrast colours, a missing quiet zone, or printing the code too small. Regenerate with the default dark-on-light colours, keep at least four modules of white border, and print at 3 cm or larger for close-range scanning.

Should I use a hidden network?

It is possible but not recommended. Hidden networks need the H flag set to true, and some phones still fail to connect from a scan. A visible guest SSID with a strong password and client isolation is both more reliable and no less private.
