How to Make a WiFi QR Code in 3 Steps

Enter your network details

Type your network name (SSID) exactly as it appears in your router settings, pick the security type, and enter the password. WPA/WPA2 is the right choice for nearly every modern network.

Generate and preview the code

Click Generate and a scannable code appears instantly. The whole tool runs in your browser, your credentials never leave the page. Point your own phone at the screen to test it before printing.

Download and print it

Grab a print-ready PNG or an infinitely scalable SVG. Print at least 2 x 2 cm with the white margin intact, then place it where guests naturally look: table tents, the counter, the guest-room folder.

What Is a WiFi QR Code?

A WiFi QR code packs your network name, security type, and password into a single scannable image. It is the fastest way to share a WiFi password: a guest points their phone camera at it, the phone reads the credentials, and offers a one-tap "Join network" prompt. No hunting through a network list, no reading a password off a chalkboard, no "is that a capital i or a lowercase L" back-and-forth.

That makes a WiFi QR code with the password embedded the standard fixture for cafes, offices, Airbnbs, and home guest rooms: print the code once, put it where people sit, and WiFi questions disappear. Both iPhone (iOS 11 and later) and Android (10 and later) recognize a QR code for WiFi natively in the camera app, so it works for virtually every guest without installing anything.

How the WIFI: Format Works

Under the hood, the QR code contains a short text string in a standard format phones understand.

WIFI:T:WPA;S:MyCafe-Guest;P:scan-to-join;H:true;;

WIFI:

The scheme prefix. Tells the phone this is a network join payload, not a URL or plain text.

T:WPA;

The security type: WPA (covers WPA2/WPA3), WEP, or nopass for open networks.

S:MyCafe-Guest;

The network name (SSID), exactly as the router broadcasts it. Case-sensitive.

P:scan-to-join;

The password, in plain text. Omitted entirely for open networks.

H:true;

Optional flag for hidden networks whose SSID is not broadcast. Left out otherwise.

;;

The terminator that closes the payload. Special characters inside values (\ ; , : ") are escaped with a backslash.

WPA vs WEP vs Open: Which to Pick

The security setting in the code must match what your router actually uses. A WPA QR code covers WPA2 and WPA3 networks too, phones negotiate the strongest protocol the router offers.

WPA/WPA2 (and WPA3)

Nearly every network made after 2006. The default choice.

Phones treat the WPA setting as "modern secured network" and negotiate the strongest protocol the router offers, including WPA3.

WEP

Legacy routers from the early 2000s only.

WEP encryption is broken and crackable in minutes. If your router only offers WEP, replacing it is a better security upgrade than any QR code.

None (open)

Genuinely passwordless networks, like some venue guest WiFi.

The code then only stores the network name, guests still join in one scan instead of hunting through a network list.

Static WiFi QR vs Dynamic QR: When Each Wins

A WiFi code must be static, the phone needs the credentials offline at scan time. For everything else you print, a dynamic QR is usually the smarter choice.

	Static WiFi QR (this tool)	Dynamic QR (Flyn short link)
What it encodes	Your credentials, directly in the image	A short link that redirects to any destination
Works with no internet	Yes, joining WiFi needs no connection	No, the scan resolves through a redirect
Change after printing	No, new password means new print	Yes, re-point the destination anytime
Scan tracking	None, there is no server involved	Total scans counted free, full breakdowns on Pro
Best for	WiFi access, one job forever	Menus, house guides, promos, booking pages

Most hosts end up printing both: a static WiFi code so guests get online, and a dynamic QR code next to it for the menu or house guide, one you can re-point after printing and measure scans on.

How Big Should You Print It?

The working minimum is 2 x 2 cm for a code scanned at arm's length, roughly a table tent or counter card. The general rule: print width should be at least one tenth of the scanning distance. A code on a wall poster read from 1 meter away should be 10 cm wide. When in doubt, go bigger, oversized codes never fail, undersized ones fail constantly.

Always keep the white quiet zone around the code (this tool includes it in every download), print dark modules on a light background, and prefer matte over glossy finishes to avoid glare. For the full sizing math, including distance tables for posters and shelf labels, see our QR code size guide.

Why WiFi QR Codes Fail to Scan

WiFi QR code not working? Six failure modes cover nearly every report. Check them in order.

Printed too small

Below 2 x 2 cm, phone cameras struggle to resolve the modules at a normal scanning distance. Scale up, especially for wall posters scanned from farther away.

Quiet zone cropped

The white border around the code is part of the spec, not empty space to trim. Crop it and many scanners cannot find the code edges.

Low contrast or inverted colors

Dark modules on a light background scan best. Light-on-dark (inverted) codes fail on many phones, and pastel-on-white lacks the contrast cameras need.

Glare from lamination

Glossy lamination reflects overhead light straight into the camera. Use matte lamination or place the code away from direct light sources.

Wrong SSID or stale password

The code fails silently if the network name has a typo or the password changed after printing. Verify with your own phone every time you reprint.

Router blocks new devices

MAC filtering or a guest-device cap on the router can reject a phone even when the code is perfect. Check the router settings if scans succeed but joining fails.

Guest WiFi QR Codes: Airbnb, Cafe, and Office

The same three-field code adapts to every place guests ask for the password.

Airbnb and vacation rentals

An Airbnb WiFi QR code in the house guide or framed on the fridge answers the most-asked question in hosting before it is asked. Guests are online before their bags are unpacked.

Cafes and restaurants

A cafe or restaurant WiFi QR code on a table tent, menu corner, or counter sign means staff never spell the password out mid-rush. Laminate it matte to avoid glare.

Office guest network

Print a code for the office guest network in reception and meeting rooms. Visitors connect in seconds, and your internal network stays untouched.

Home guest room

A small WiFi QR code sign on the guest-room nightstand beats texting the password to every visiting relative, and it still works when your phone is elsewhere.

Always point it at a guest network

Because the QR code hands out your password in plain text, the smart move for any business (and most homes) is to point it at a dedicated guest network. Nearly every modern router supports one: guests get internet, but they are isolated from your main network, your POS system, your printers, and your laptops. If a guest device is compromised, the blast radius is the guest VLAN, not your business.

A guest network also makes password rotation painless: change the guest password quarterly, reprint one card, and your main network credentials never circulate at all. For a deeper walkthrough, including router-by-router setup and printable sign ideas, read our complete WiFi QR code guide.

Frequently Asked Questions

How does a WiFi QR code work?

The code encodes your network name, security type, and password in a standard text format (WIFI:T:WPA;S:name;P:password;;) that phone cameras understand natively. When a guest scans it, the phone shows a "Join network" prompt and connects with the stored credentials. No app is needed on any modern iPhone or Android phone.

Is it safe to put my WiFi password in a QR code?

The password is stored in the code as plain text, so anyone who scans it can read the password with a decoder app. Treat a WiFi QR code exactly like a card with the password printed on it: perfect for a cafe counter or guest room, wrong for a network that protects sensitive systems. For businesses, put the code on a separate guest network so scanners never touch your main one.

Does the QR code stop working if I change my WiFi password?

Yes. The password is baked into the printed pattern, so changing your router password means printing a new code. That is the nature of every static WiFi QR code, not a limitation of this tool. If you rotate passwords often, keep this page bookmarked, regenerating takes ten seconds.

Which security type should I pick: WPA, WEP, or None?

Pick WPA/WPA2 unless you know otherwise, it covers WPA, WPA2, and WPA3 networks, which is nearly every router made since 2006. WEP exists only for legacy hardware and is trivially crackable, so upgrade the router if you still run it. Choose None only for genuinely open networks with no password.

Do WiFi QR codes work on both iPhone and Android?

Yes. iPhones running iOS 11 or later (2017) and Android phones running Android 10 or later join directly from the native camera. Older Android versions may need Google Lens or a QR scanner app, both free. The format is a cross-platform standard originally popularized by ZXing, so any compliant scanner understands it.

Do guests need an app to scan the code?

No. The built-in camera app on modern iPhones and Android phones recognizes WiFi QR codes automatically and shows a join prompt. Guests point the camera at the code, tap the notification, and they are on the network. That is the whole appeal: zero typing, zero misspelled passwords, zero support questions.

Does this tool store my WiFi password?

No. The code is generated entirely in your browser with JavaScript, and your network name and password never leave this page. The recent-networks list stores names only, passwords are deliberately never written to localStorage or sent to any server.

What if my network name or password contains special characters?

The tool escapes backslashes, semicolons, commas, colons, and double quotes automatically, per the WiFi QR specification. So an SSID like "Cafe;Sol" or a password with punctuation encodes correctly. Emoji and non-Latin characters also work, they are encoded as UTF-8, which modern phones read fine.

How big should I print a WiFi QR code?

A minimum of 2 x 2 cm works at arm's length, but bigger is safer: the rule of thumb is print size = scan distance divided by 10. A code on a table tent scanned from 30 cm should be at least 3 cm wide. Leave the white quiet zone around the code intact, cropping it is the most common reason codes fail.

Can I make a QR code for a hidden network?

Yes, tick the "Hidden network" checkbox and the code includes the H:true flag. That tells the phone to connect to the SSID even though the router does not broadcast it. Without the flag, phones may refuse to join a network they cannot see in a scan list.

Why is my WiFi QR code not working?

The usual culprits are printing too small, cutting off the white margin, low contrast between the code and its background, or glare from lamination. Reprint at higher contrast with the quiet zone intact and test with both an iPhone and an Android phone before laminating. Our guide on QR scan failures covers each fix in detail.

Does a WiFi QR code expire?

No. Your QR image itself never expires, the credentials are baked into the pixels and there is no server between the scan and the connection, so there is nothing to deactivate. Some QR services route codes through their servers and kill them when a trial ends; a code downloaded from this tool is yours forever. The same goes for short links in a Flyn account, free or paid, we never deactivate them because a trial ended or a plan changed. Only anonymous trial links made with our shortener tools, without an account, expire after 24 hours.

What is the easiest way to share a WiFi password with guests?

A scan-to-connect QR code. Sharing a WiFi password through a QR code removes the two classic failure points, mishearing it and mistyping it, and it works even when you are not around to recite it. Print the code once, place it where guests sit, and for businesses point it at a dedicated guest network so the shared password never exposes your main systems.
