Stop reading your WiFi password out loud. Make a code your guests point a camera at, print it on a card for the wall — or scan a WiFi QR you already have to read it back. Your password is encoded in this tab and never sent anywhere.
Higher levels survive scuffs and glare but make the code denser. M is right for a printed card; use H if you add a logo or the code will live somewhere it gets touched.
Up to 2 MB. Adding a logo switches error correction to H so the code still scans with part of it covered.
Fifteen templates for the places these actually get stuck: a guest room, a counter, a reception desk, a classroom wall. Pick one, edit the wording, print it.
Worth printing for laptops and older phones, which cannot join from a code. Leave it off in a public room where the card is on show and only phones will use it.
Read an existing WiFi QR code — a card in a hotel room, a sticker on a router, or a screenshot someone sent you.
It decoded to the text below. WiFi codes start with WIFI:.
Enter your network name and password and the code appears here.
Open the Camera app and point it at the code. Tap the Join WiFi Network banner at the top. Works from the lock screen, iOS 11 and later.
Open the Camera app or Google Lens and point it at the code, then tap the network prompt. On Android 9 and older, use the QR button in Settings → Network & internet → WiFi.
Desktop operating systems do not join WiFi from a QR code. Scan it with a phone, or read the password off the printed card and type it in.
There is no button here that connects you, because no browser is allowed to change your WiFi. Any page offering one is either opening your settings app or pretending.
Fill in the network details on the Create tab to see your card.

A WiFi QR code contains your password in plain text. That is how the standard works — the phone needs it to join. So the only question that matters is who else sees it, and the answer here is nobody.
The QR code is drawn by JavaScript in this tab. There is no server that generates it and none that could.
No request carries your network name or password. Open your browser's network panel and check — that is the point of saying it.
Nothing is written to the URL, so your password cannot end up in browser history, a bookmark or a shared link.
Only your colour and shape choices are remembered between visits. Credentials are deliberately left out of that.
We count page views. No event on this page carries a field you typed.
The scanner releases the camera the instant it reads a code, and again if you switch tabs. Frames are never recorded.
One honest caveat, since it is the thing people get wrong: a printed WiFi card is readable by anyone who can photograph it. The privacy guarantee is about this website, not about the wall you tape it to. For a network you care about, use your router's guest network and put that password on the card instead.

Copy the SSID exactly as your phone shows it. Case matters, spaces matter, and a trailing space you cannot see is the single most common reason a WiFi QR code fails.
WPA/WPA2/WPA3 covers essentially every router made this century. WEP is for genuinely old equipment. Open is for a network with no password at all.
It goes straight into the code, never to a server. Semicolons, colons, quotes and backslashes are escaped for you, so an awkward password is not a problem.
Point your own phone at the code on screen. If it offers to join, everything after this is just formatting. If it does not, check the SSID for typos first.
PNG for screens and small prints, SVG for anything larger than a postcard. Or pick a card template and print a finished sign.
Eye level, out of direct glare, and big enough — roughly 1 cm of code for every 25 cm of scanning distance. Behind glass on a reception desk is the usual failure.
A WiFi QR code is an ordinary QR code that holds one short line of text in a format phones recognise. It looks like this:
WIFI:T:WPA;S:My Home WiFi;P:hunter2example;H:false;;
T is the security type, S the network name, P the password and
H whether the network is hidden. When a camera decodes text starting with WIFI:,
the operating system offers to join that network instead of opening a browser. There is no lookup, no
account and no service in the middle — everything the phone needs is in the code itself, which is why a
WiFi QR code still works years later and keeps working if the site that made it disappears.
The format came out of the ZXing project and was adopted by Android and then iOS. It is not a formal
internet standard, which is why the details matter: characters like ; and : have
to be escaped inside the values or the phone reads the password as the end of the field. This generator
handles that for you, and the scanner on this page reads it back the same way.
On any iPhone running iOS 11 or later, open the Camera app and hold it over the code. A banner slides down saying Join WiFi Network; tap it and you are on. You do not need to take a photo, open an app or unlock into anything — it works from the lock screen.
Android 10 and later behave the same way through the built-in camera or Google Lens. On Android 9 and earlier there is no camera integration, but the WiFi settings screen has its own scanner: go to Settings → Network & internet → WiFi, tap Add network, and use the QR icon next to the name field. Most Android phones can also generate a code for the network they are already on from the same screen, which is a quick way to check that yours matches.
Laptops are the gap. Neither Windows, macOS nor most Linux desktops will join a network from a QR code, so if guests bring laptops, print the password as text on the card as well. That is what the print the password option on the card designer is for.
The pattern is always the same: somewhere a password gets read out loud several times a day, and gets typed wrong about a third of those times.
A card on the desk or inside the welcome folder removes the most repeated question at the front desk, and it removes it in every language your guests speak. Put the QR on the same card as the room number and the checkout time and it gets read. If your property runs a per-room or per-stay password, generate a fresh code when the password rotates — it takes about fifteen seconds and the old cards simply stop working, which is the behaviour you want.
Tape it to the inside of the menu, or print it as a small table tent. Restaurants have the strongest case for a guest network with a separate password: the code will be photographed by strangers, and you do not want the network holding your card terminal behind the same key. A short, friendly SSID also helps, because guests glance at the network name to check they joined the right one.
Cafes are where people sit down and open a laptop, so this is the one setting where printing the password as text next to the code genuinely matters — laptops cannot scan. Keep the card near the counter rather than on each table; it stays cleaner and people expect to look for it while they wait. Matte card stock beats a laminated sheet, because gloss under a spotlight defeats phone cameras.
Guests arrive tired, often late, and frequently with a phone on the last of its battery. A framed card by the door is the highest-value five minutes of setup in the whole property, and it heads off the message at eleven at night asking for the password. Add it to your digital guidebook as an image too: a guest reading the guidebook on their phone can screenshot the code and scan it from another device.
Meeting rooms are the obvious place — a visitor should not need to find someone to get online before a presentation. Use the guest VLAN, not the staff network, and treat the printed code as a credential that needs rotating on the same schedule as the password behind it. A code stuck on a wall in 2021 with a password nobody has changed since is a genuine finding in a security review.
Almost every router made in the last decade can run a second network with its own name and password, isolated from the devices on your main one. That is the right thing to put behind a QR code, at home or in a business. It means a scanned code gives someone the internet and nothing else — not your network drive, not your printer, not the camera in the hallway.
Home passwords tend to be the long random string printed on the underside of the router, which is precisely the kind of thing nobody wants to read out character by character. A small card in the hallway or on the fridge solves it permanently, and it works for babysitters, relatives and trades without you having to be there.
Print the code on the badge, the lanyard insert or the back of the programme, and repeat it on the slides between sessions. Attendees join in the first minute rather than during the opening talk. For venue WiFi you do not control, ask for the guest credentials in advance and generate the code yourself — venues rarely have one ready, and the alternative is a password projected on a screen at the back of a room.
Customers who stay connected stay longer, and a code at the till or in the waiting area costs nothing to put up. Keep the SSID recognisably yours — a guest looking at a list of nearby networks should be able to tell which one is the shop they are standing in.
Both have the same shape of problem: a lot of visitors, a network that must stay separated from sensitive systems, and staff who should not be spending their day on connection support. A printed guest code in reception and in waiting areas handles it. Keep the clinical or administrative network well away from anything printed.
The obvious benefit is that nobody types anything, which matters more than it sounds. A modern WPA2 password is long and deliberately unmemorable, and typing it into a phone keyboard is where the mistakes happen. A code removes the transcription step entirely, and with it the round of "is that a capital I or a lowercase L".
It also removes the moment where the password is read out across a room. Saying it aloud in a busy cafe reaches more people than the QR code on the counter ever will, and a code lets you use a longer, stronger password than you would ever be willing to dictate.
Finally, it looks finished. A printed card with your own wording and colours reads as somewhere that has thought about the guest, in a way that a password biroed onto a Post-it does not. That is a small thing, but it is the first thing a guest touches.
The trade-off is worth stating plainly: the password is in the code in the clear, and a code on a wall is a password on a wall. Use a guest network, rotate it when it makes sense, and the trade is a good one.

It is an ordinary QR code containing a short line of text in a standard format: WIFI:T:WPA;S:NetworkName;P:password;;. Phone cameras recognise that format and offer to join the network instead of opening a web page, so a guest connects without typing anything.
Type your network name and password into the generator on this page and pick your security type — WPA/WPA2/WPA3 for almost every modern router. The QR code appears as you type. Test it with your own phone, then download it as a PNG or SVG or print it as a WiFi card.
Yes. On iPhone (iOS 11 and later) and Android (version 10 and later) the built-in camera app recognises a WiFi QR code and shows a prompt to join the network. Older Android phones can scan the same code from the QR button in the WiFi settings screen.
Yes — it has to, because the phone needs the password to join. The password is stored as plain text inside the code, not encrypted. Anyone who can photograph the code can read the password out of it, so treat a printed WiFi card the same way you would treat the password written on a sticky note.
Yes, completely. There is no sign-up, no watermark on your QR code, no limit on how many you make, and no paid tier. The codes never expire and do not stop working if this site goes away — a WiFi QR code is a self-contained piece of text, not a link back to us.
No. The QR code is generated by JavaScript running in your browser. Your network name and password are never sent to a server, never written into the page URL, never saved to your browser's storage and never included in analytics. You can open your browser's network panel and watch: nothing carrying your password is sent.
Yes. Open the Camera app on iOS 11 or later and point it at the code. A notification appears at the top of the screen saying "Join WiFi Network" — tap it to connect. It works from the lock screen too, and no third-party app is needed.
Yes. Android 10 and later recognise WiFi QR codes in the built-in camera and in Google Lens. On older versions, go to Settings, then Network & internet, then WiFi, and use the QR scan button next to Add network. Samsung, Pixel and most other Android phones can also share their current network as a QR code the same way.
Yes. Turn on the Hidden network switch and the code will include the hidden flag, which tells the phone to search for a network that is not broadcasting its name. Without that flag most phones will scan the code and then report that the network cannot be found.
Yes, as a PNG at up to 2048 pixels or as an SVG. The SVG is vector, so it stays sharp at any size — use it if the code is going on a poster, a menu or anything printed larger than a postcard. You can also export a finished WiFi card as a PNG or a PDF.
Yes. Pick one of the 15 card templates, edit the heading and the message, and print it directly or save it as a PDF. Print the QR code at least 3 cm across for a card people hold, and larger for anything read from across a room — roughly 1 cm of code for every 25 cm of scanning distance.
No, and no browser is planning to allow it. A list of nearby network names is enough to locate a device to within a few metres, so scanning is restricted to the operating system behind a permission prompt. Any site claiming to show you nearby networks is either guessing from your IP address or making it up. The Network Information API comes closest and it only describes the connection you already have, never its name.
