WiFi QR Code Generator

Let guests join your network by scanning a code instead of typing a long password. Built in your browser — your password is never sent anywhere.

Network name (SSID)

Exactly as it appears in your WiFi list — capitals and spaces included.

Password

Use the eye button to check it before printing.

Security

Hidden network (does not broadcast its name)

Your QR code will appear here.

How a WiFi QR Code Works

There is no image format for "WiFi". A WiFi QR code is just a QR code containing one line of text in a specific shape, which phones recognise and turn into a join-network prompt:

WIFI:T:WPA;S:MyNetwork;P:MyPassword;;

T is the security type, S the network name, P the password, and H:true marks a hidden network. That is the whole format. Which leads directly to the thing most generators get wrong.

The escaping problem — and why some WiFi QR codes silently fail

Because ; and : separate the fields, a password containing one of them would cut the record in half. The format therefore requires five characters — ; : , \ and " — to be escaped with a backslash when they appear inside a value. A password of pa;ss has to be encoded as pa\;ss.

Plenty of generators paste your password in unescaped. The resulting code looks completely normal, scans fine, and then either fails to connect or joins with a mangled password — with no error that points at the cause. This tool escapes those characters and tells you when it did, so you can see it happen.

Which Devices Can Scan a WiFi QR Code

Device	Support
iPhone / iPad	iOS 11 and later: point the built-in Camera app at the code and tap the prompt.
Android	Android 10 and later: the camera or Settings handles it natively. Earlier versions usually need a QR scanner app.
Laptops	No native support — a laptop has no reason to scan. Keep the password available for those.
Smart TVs, consoles, printers	No camera, so no scanning. These are exactly the devices where an easy-to-type password matters.

Because of that last row, a QR code complements a good password rather than replacing one. Generate a strong, typeable password with our WiFi password generator, then make a QR code from it for the phones.

WPA3 and the Security Setting

The format has no separate WPA3 marker. Use WPA for WPA, WPA2 and WPA3 alike — the device negotiates the strongest protocol your router offers. Pick WEP only for genuinely ancient equipment (and replace that router), and "No password" only for a genuinely open network.

Printing and Sharing It Sensibly

Print it reasonably large. The downloaded PNG is sized for printing; roughly 3 cm across is plenty for a phone at arm's length.
Keep the white border. That margin around the code is part of the standard — crop it off and scanners struggle.
Do not invert the colours. Dark-on-light is what scanners expect; a light-on-dark code is rejected by some readers. This tool always renders dark-on-light, in both light and dark mode.
Remember what it contains. The code holds your password in plain text. Anyone who can photograph it can read the password, so a code taped in a public place is a written-down password. For a café or an office, put the QR code on the guest network, not the main one.

Frequently Asked Questions

How do I create a WiFi QR code?

Enter your network name (SSID) exactly as it appears, enter the password, pick the security type (WPA/WPA2/WPA3 for almost every modern router), and the QR code appears instantly. Download it as a PNG and print it or stick it on the fridge. Guests point their phone camera at it and get a prompt to join - no typing.

Is it safe to generate a WiFi QR code online?

With this tool, yes: the QR code is built entirely inside your browser using JavaScript, and neither the network name nor the password is ever sent to a server. Be aware of what the code itself means, though - a WiFi QR code contains your password in plain text, so anyone who can photograph it can read your password. Treat a printed code like a written-down password.

Can iPhones and Android phones scan WiFi QR codes?

Yes. iPhones running iOS 11 or later scan WiFi QR codes with the built-in Camera app. Android 10 and later does the same from the camera or from Settings. Older Android versions may need a QR scanner app, and some very old devices cannot join from a code at all - keep the password written down as a fallback.

Which characters break a WiFi QR code?

The WiFi QR format stores the network as WIFI:T:WPA;S:name;P:password;; so semicolon, colon, comma, backslash and double quote are structural characters and must be escaped with a backslash inside the password. Many generators skip this, producing a code that looks fine and silently fails. This tool escapes them and tells you when it did.

Does a WiFi QR code work with WPA3?

Yes. The QR format has no separate WPA3 marker - you use the WPA type for WPA, WPA2 and WPA3 alike, and the device negotiates the strongest protocol the router offers. Choose WEP only for genuinely old equipment, and No password only for a genuinely open network.

Can I make a QR code for a hidden WiFi network?

Yes - tick the hidden network option. That adds an H:true field telling the phone the network does not broadcast its name, so it will connect instead of searching for a visible network and failing. If you tick it for a normal broadcasting network, some devices will still connect but others may not, so only use it for genuinely hidden networks.
