📶 WiFi QR Code Generator

The QR code holds a short line of text in a format phones understand: the network name, the password, and the security type. When a phone camera reads it, the operating system recognises the WIFI: prefix and offers to join that network instead of opening a web page. Nothing is downloaded and no app is involved — the credentials travel the same way they would if you typed them in by hand.

The QR code is just your password in a machine-readable shape. Anyone who can photograph the code can extract the password, so treat a printed code exactly as you would treat the password written on a card. Print it for your own wall, not for the internet. If you are putting one on display in a rental, an office lobby, a clinic waiting room, or anywhere the public can see it, point it at your guest network rather than your main one. Most routers made in the last decade can run a separate guest network with its own password and no access to your computers, printers, or cameras.

No. The QR code is built in your browser using JavaScript that is served from this site, and nothing you type is transmitted, logged, or stored anywhere. There is no form submission and the values never appear in the web address. The page does load Google Analytics, which records that someone visited the page but never receives anything you type. Nothing else is requested from a third party. You can disconnect from the internet after the page loads and the generator will still work.

iPhones and iPads have read WiFi QR codes from the built-in Camera app since iOS 11, so point the camera and tap the banner that appears. Android has supported it natively since Android 10, and Google Lens handles it on older versions. Some Samsung and Pixel devices can also display a QR code for a network you are already on, which is a quick way to check that yours works. If a camera opens a browser instead of offering to connect, the code was almost certainly built with the wrong format or bad escaping.

Choose WPA/WPA2/WPA3 unless you know otherwise — it covers essentially every home and office network in use today, and WPA3 networks read it correctly. Choose WEP only for genuinely ancient equipment. Choose No password for an open network, in which case the password field is ignored entirely. Some generators emit a special WPA3 or SAE value here, which looks more precise but fails to scan on older phones for no benefit at all.

Four common causes. First, a typo in the network name: it must match the broadcast name exactly, including capital letters and spaces. Second, special characters that were not escaped properly — semicolons, commas, colons, backslashes, and quotation marks inside a name or password all need escaping, which this page does for you. Third, printing the code too small or too pale: keep it at least one inch across and print in black on white. Fourth, a hidden network without the hidden box ticked, which makes phones look for a network that is not broadcasting.

Yes, but you have to tick the hidden network box so the code carries the flag telling the phone to search for a network that does not broadcast its name. Without it, the scan will appear to work and then fail to find anything. Hiding a network is worth mentioning here: it does not make you meaningfully safer, and it does make every device harder to connect.

About one inch square is the practical minimum for a phone held close, and larger is better if the sign will sit across a room. The rough rule is that scanning distance is about ten times the width of the code, so a two-inch code reads comfortably from around twenty inches. The full-page sign on this page prints far larger than it needs to be on purpose, because a sign on a wall gets read from further away than anyone expects.

Yes, in two forms. The printable sign downloads give you the finished layout, complete with the heading, the network name and the password, as a PDF, a PNG at 300 dots per inch, or an SVG. The QR code only downloads give you the bare code with nothing around it, as a PNG at 1200 pixels or an SVG, which is what you want when you are dropping it into your own design, a slide, or a welcome book. Choose SVG whenever the thing will be printed large, because it is vector and stays sharp at any size. Choose PNG when you need a plain image a phone or a word processor will accept without fuss.

No, on both counts. This page needs nothing but a browser, and modern iPhone and Android cameras scan WiFi codes without any app installed. A guest with a genuinely old phone may need a QR scanner app, which is why the printable layouts also show the network name and password as text underneath.
