Wi-Fi QR Code Generator
Let people join your Wi-Fi by scanning.
Enter the network name and password below. Scanning the finished code prompts a phone to join the network directly. No password read aloud, no laminated sign, no typing a string of random characters into a phone keyboard.

Scanning opens the phone's default maps app centered on this point.
The end time must be after the start time.
Leave the date blank to preview with a sample event. Defaults to a 1-hour event if no end time is set.

Light backgroundsLight dots read fine on dark backgrounds on screen, but most scanners are tuned for dark-on-light -- test before printing at volume. Scan reliability tips.
No background means no contrast check. Place this on a light, solid area; a dark or busy backdrop will stop it scanning. Scan reliability tips.
These colors are close in tone and may be hard for some scanners to read. Consider more contrast. Choosing colors that scan.

Logo Your artwork, or one of ours
Manage these under Assets in your profile.
Use only artwork you have the right to use. A logo you add is yours to clear: trademarks and copyright belong to whoever owns them.
Drawn for this product, so there is nothing to clear. These are yours to use.
Create a free account to save this logo and reuse it on any code.
This logo isn’t in your library, so saving this code won’t keep it, and the code will reopen without it. Save the logo above first.
We tested this against a real scanner: codes start failing between 16% and 20% of the area, so 15% is the safe ceiling. How we measured it.

Nice one. Want to keep this design?
Create a free account and this exact style, colors, shapes and logo, is one click away next time. Free accounts also get 2 dynamic QR codes you can repoint after they are printed.
Dynamic QR codes redirect to a web address, so they're available for the URL and WhatsApp types. Other types encode their content directly and can't be repointed later.

You will see this page load its own files: a stylesheet, two typefaces from Google Fonts, and our analytics. Like most sites, this one loads those. What you will not see is a request carrying the link you typed, the contents of your code, or the image itself, because the code is drawn here on your device and there is nowhere for it to be sent.
Understand what you are printing
The password is inside the code in plain text. There is no encryption and no lookup. Anyone who scans it, or photographs it and decodes it at home a week later, has your password. That is how the format works, on every generator that produces one.
Treat a printed Wi-Fi code as equivalent to writing the password on the wall, because functionally that is exactly what it is. For a café that is completely fine and is the entire point. For the network your file server and printers sit on, it is not.
The fix is one setting on your router, not a different QR code: put visitors on a separate guest network and generate the code for that. Then a leaked password buys someone internet access, which you were giving away anyway, rather than a foothold on your LAN.
The three fields people get wrong
- The network name is matched, not displayed. It has to be exactly right, including capitalization and spaces, because the phone compares it against the networks it can actually see.
Cafe Guestandcafe guestare two different networks, and only one of them exists. - Security type has to match reality. WPA/WPA2 covers essentially every modern network, WPA3 included in practice. WEP is long obsolete and is only there for genuinely old hardware. Choosing No password removes the password field entirely, because there is nothing to encode.
- Hidden network is not cosmetic. If your SSID is not broadcast, the phone cannot find it by name and the code fails silently unless that box is ticked. If it is broadcast, leave it alone; ticking it unnecessarily causes its own problems.
Paste your real password, symbols and all
Semicolons, colons, commas, backslashes and quotes are field delimiters in this format. A password containing one would, in a naive generator, corrupt every field after it, producing a code that looks perfect and joins nothing.
This generator escapes them for you, so paste the password exactly as it is. You do not need to simplify it, and you should not.
In fact this is the argument for making guest passwords longer. The reason guest passwords are short is that humans have to type them. Once nobody types it, that constraint disappears, and a long random passphrase behind a scannable code is both easier for guests and considerably harder to guess than coffee123.
Print it big enough, and somewhere you can swap it
Wi-Fi codes encode a network name, a password and a security type, so they are denser than a short link: a finer grid that needs more printed area to stay reliable. A table tent at a couple of inches across is comfortable. A tiny code tucked into the corner of a menu is where these fail.
Second, plan for rotation. The credentials are baked into the pattern, so the day you change the password every printed code becomes wrong simultaneously. Table tents and card holders you can reprint beat vinyl laminated to a wall. A Wi-Fi code also cannot be made dynamic, because the phone reads the credentials straight out of the pattern and never contacts a server, so there is nothing to repoint.
Frequently asked questions
Does this work on both iPhone and Android?
Yes, and it is one of the most reliably supported QR types there is. Both platforms' built-in camera apps recognize the format and offer to join: iOS since iOS 11, Android natively since Android 10 and earlier via Lens.
Someone scanned it and nothing happened.
Most often the phone is out of range. The prompt only appears when the network is actually visible, or when Hidden network is ticked. After that, check the name for a typo or wrong capitalization and confirm the security type. A third-party scanner app is the other common cause: many just display the raw text instead of acting on it. Use the built-in camera.
Is it safe to put this in a shop window?
Only if it is a guest network you are content for passers-by to use, since anyone who can photograph it can read the password. That is usually fine for the intended purpose. What is never fine is doing it with the password to the network your business actually runs on.
Can I add my logo to it?
You can, but be conservative here specifically. Wi-Fi codes are dense, and the denser the code the less area a logo can safely cover before error correction runs out. The generator warns you when the combination gets risky. Heed it, and test the printed proof with a real phone rather than the screen.
Do I have to reprint when the password changes?
Yes. The credentials are part of the printed pattern, so an old code simply stops working. If you rotate guest passwords on a schedule, print the code onto something you can replace in seconds.
