WiFi QR Code Generator

Q: Does a Wi-Fi QR code work on both iPhone and Android?

Yes. iOS has read the WIFI: format in the built-in Camera app since iOS 11, and Android since version 10 (earlier versions need a scanner app or Google Lens). Both show a 'Join network' prompt rather than joining silently, so the person scanning always confirms first.

Q: Can someone read my Wi-Fi password from the QR code?

Yes — assume they can. The password is stored in the code as plain text, and any scanner app can display it instead of connecting. A Wi-Fi QR code is a convenience, not a security measure. Put it on a guest network rather than the network your NAS and printers sit on, and do not post one anywhere the public can photograph it if the password also protects something else.

Q: Why does my code scan but fail to connect?

Three causes account for almost all of it. The SSID is spelled or capitalised differently from the real network; the network is hidden and the code does not say so; or the password contains a semicolon, comma, colon, backslash or quote that was not escaped by whatever tool built the code. This tool handles the escaping and reports it, and the hidden-network checkbox covers the second case.

Q: Will the code still work if I change my Wi-Fi password?

No. The password is baked into the code itself, so changing it makes every printed copy dead. There is no way to update a code after printing without generating a new one — this is a static code, and nothing about it phones home. If you rotate the guest password on a schedule, print the code on something cheap to replace.

Make a QR code that connects a phone to your Wi-Fi without anyone typing the password.

What It Does

This tool turns a network name and password into a WIFI: payload that Android and iOS both understand natively. A guest points their camera at it, taps the prompt, and joins — no password read aloud across a room, no typos, no laminated card by the door. The code is built entirely in your browser, so the password never leaves your machine.

When to Use It

You run a cafe or salon and want guests on the Wi-Fi without staff repeating a 20-character password all day.
You are setting up a holiday rental and want a card by the door that works for every guest without your involvement.
Your office has a guest network and you want a code on the meeting-room wall instead of a whiteboard scrawl.
Your home password is long and random because it should be, and typing it into a visitor's phone is the only reason you ever consider shortening it.

Worked Examples

CafeGuest / WPA2

A straightforward guest network. Note the analysis reporting the code as low density — a short SSID and password give large modules that scan from across a room.

Password containing a semicolon

The semicolons are field terminators inside the WIFI: payload. Watch the analysis report which characters it escaped — without that escaping the password would be read as just 'sun' and the code would connect to nothing.

Hidden network

A network whose SSID is not broadcast. The hidden flag is what makes the phone search for it explicitly — leave it off and the code scans perfectly but never finds the network.

Common Mistakes

Not escaping semicolons, commas, colons, backslashes and quotes in the password. These characters terminate fields inside the WIFI: payload, so a password of 'sun;flower' is read as 'sun' and the code silently connects to nothing. This tool escapes them for you and tells you which ones it had to escape.
Getting the SSID case wrong. Network names are case-sensitive, so 'CafeGuest' and 'cafeguest' are different networks — and the phone will simply fail to find one of them with no useful error.
Leaving the security type on WPA for an open network. If the network has no password, set the security to 'No password' — a code that claims encryption on an open network fails on many Android builds.
Forgetting to tick 'Hidden network' for an SSID that is not broadcast. A phone will not find a hidden network from a code that does not flag it, and this is the single hardest Wi-Fi QR failure to diagnose because everything looks correct.

How to Use

1. Type your network name (SSID) exactly as it appears in the Wi-Fi list — it is case-sensitive. 2. Type the password, special characters and all; escaping is handled for you. 3. Pick the security type, and tick 'Hidden network' if the SSID is not broadcast. 4. Read the scannability analysis, then download as PDF or SVG if you are printing it.
