WiFi QR Code Generator

The Wi-Fi QR Code Generator creates a scannable QR code that lets any phone join your wireless network instantly — no reading a long password off a sticker and typing it in by hand. Enter your network name, password, and security type, and the tool builds the code right in your browser.

Point a modern iPhone or Android camera at the finished code and a "Join Network" prompt appears in a second. Because everything is generated locally, your Wi-Fi password never leaves your device.

How to make a Wi-Fi QR code

1. Type your network name exactly as it appears, including capital letters, into the SSID field.
2. Choose the encryption type: WPA/WPA2/WPA3 for almost all modern routers, WEP for very old ones, or None for an open network.
3. Enter the password (skip this if the network is open).
4. Tick hidden network if your router does not broadcast its name.
5. Click Generate, then Download PNG to save or print the code.

What is a Wi-Fi QR code?

A Wi-Fi QR code stores your network's connection details in a single standardized string that phones know how to read. The format looks like WIFI:T:WPA;S:MyNetwork;P:MyPassword;;, where T is the security type, S is the network name, and P is the password.

When a camera scans it, the operating system parses those fields and offers to connect — the same experience as the codes printed on cafe walls and hotel welcome cards.

Where should I use one?

Print it and stick it by the router for house guests, drop it on a poster in a waiting room or shop, or add it to an event handout. Anywhere people repeatedly ask "what's the Wi-Fi password?" is a good place for a scannable code.

Why escaping special characters matters

The Wi-Fi QR format uses semicolons and colons as separators, so if your password contains a character like ; , : " or a backslash, it must be escaped with a leading backslash or the code will break.

This tool escapes those characters for you automatically. A password such as p;a,ss is encoded as p\;a\,ss inside the payload, so the phone reads the whole password correctly instead of stopping at the first semicolon.

Do I need a special app to scan it?

No. The native camera app on current versions of iOS and Android recognizes Wi-Fi QR codes without any extra software. Older phones may need a dedicated QR scanner app, but the code itself follows the same universal standard.

Security and privacy

Sharing a QR code is exactly as secure as sharing the password itself — anyone who can scan the code can join the network, so treat a printed code the way you would treat the written password. For guests you do not fully trust, a separate guest network is the safest option.

All generation happens client-side, so your SSID and password are never transmitted anywhere. Need codes for other things? The general QR Code Generator handles links, text, email, and phone numbers, while the QR Code Decoder reads existing codes back into plain text. For retail and inventory labels, the Barcode Generator produces standard 1D barcodes.

Frequently Asked Questions

Is my Wi-Fi password uploaded to a server?

No. The QR code is generated entirely in your browser with client-side JavaScript. Your network name and password are never sent to, stored on, or seen by any server.

Which encryption type should I choose?

Choose WPA/WPA2/WPA3 for virtually every modern router, as they all use the same "WPA" type value in the QR payload. Pick WEP only for very old equipment, and None for open networks that have no password.

Will the code work if my password has special characters?

Yes. Characters like semicolons, commas, colons, quotes, and backslashes are automatically escaped in the payload, so passwords with tricky symbols still scan and connect correctly.

Do phones need an app to scan a Wi-Fi QR code?

Most do not. The built-in camera on recent iPhone and Android devices reads Wi-Fi QR codes natively and shows a prompt to join. Older phones may need a separate QR scanner app.

What does the hidden network checkbox do?

It adds an H:true flag to the payload, telling the phone the network does not broadcast its name. Enable it only if your router is configured to hide its SSID, otherwise leave it unchecked.

Can I print the QR code or put it on a poster?

Yes. Download the code as a PNG and print it at any size. Higher error-correction levels make the code more tolerant of smudges or partial damage, which helps on physical prints.
