Stop spelling out "the password is lowercase-b-capital-R-seven-underscore..." to every guest. Create a WiFi QR code once, and anyone can connect to your network by pointing their phone camera at it. Takes 30 seconds. Free. No app needed.
Every time a guest asks for your WiFi password, the same awkward ritual plays out: you dictate it character by character, they mistype it, you spell it again, and eventually someone pulls out the router to read the sticker on the back. WiFi QR codes eliminate this entirely.
When someone scans a WiFi QR code, their phone automatically connects to the network using the embedded credentials. No typing. No mistakes. No revealing your password in a group chat where it lives forever. Both iOS (11+) and Android (10+) support this natively through their built-in camera apps.
For businesses, it is even more valuable. Restaurants, hotels, co-working spaces, and clinics can print a QR code on a table tent, a wall sign, or a menu card. Guests scan and connect in two seconds. No staff time spent on password support, no need to change signage when the password rotates (just regenerate and reprint the QR code).
You need three pieces of information: your network name (SSID), your password, and your encryption type. The SSID is the name that appears when you search for WiFi on your phone. The encryption type is almost always WPA/WPA2 for modern networks. If you are unsure, check your router’s settings page (usually at 192.168.0.1 or 192.168.1.1) or the sticker on the back of the router.
Go to pure-flon.com/tools/qr-generator and select the WiFi tab. The generator runs entirely in your browser — your WiFi password is never sent to any server, which makes it safe even for networks with sensitive access.
Type your SSID exactly as it appears on your network (including capitalization and spaces). Enter the password. Select the encryption type from the dropdown: WPA/WPA2 is correct for nearly all modern routers. If your network has no password (open network), select None.
Click Generate. Your QR code appears instantly. Download it as PNG (for digital use, messaging, email) or SVG (for printing at any size without losing quality). SVG is ideal for posters and signage because it stays sharp at any resolution.
Print the QR code and place it where guests can see it. Popular spots: on the fridge at home, near the front door, at the reception desk, on restaurant table tents, inside hotel room folders, or on co-working space welcome boards. Tip: make it at least 2×2 cm for reliable scanning.
WiFi QR codes use a standardized text format that mobile operating systems recognize automatically. When you encode your WiFi credentials, the QR code contains a string like this:
Here is what each part means:
| Parameter | Meaning | Example |
|---|---|---|
| T | Encryption type | WPA, WEP, or nopass |
| S | SSID (network name) | MyHomeNetwork |
| P | Password | Sup3rS3cure! |
| H | Hidden network (optional) | true or false |
The T field accepts three values: WPA covers both WPA and WPA2 (and WPA3 in most implementations). WEP is for legacy networks. nopass is for open networks with no password. If your SSID or password contains special characters like semicolons, colons, commas, or backslashes, they need to be escaped with a backslash — but our generator handles this automatically.
If your router was made after 2006, it almost certainly uses WPA2. This is the correct choice for 90%+ of home and business networks. When in doubt, select this one. WPA3 networks also work with the WPA setting in most QR implementations.
WPA3 is the latest security standard, found on routers from 2020 onward. Most WiFi QR code implementations treat WPA3 the same as WPA. If your QR code does not connect, try using WPA as the encryption type instead.
WEP is an outdated encryption standard that was cracked decades ago. If your network still uses WEP, you should upgrade to WPA2 or WPA3 for security. It still works with WiFi QR codes, but the network itself is not secure.
For networks with no password at all. Common in some public spaces. The QR code will only encode the SSID, and scanning it will connect the device without any password prompt.
Print and stick on your fridge or near the router. Guests scan instead of asking for the password. Update it whenever you change your WiFi password.
Place on table tents, menus, or at the counter. Eliminates the most common question staff get asked. Pair it with a branded design or laminated card.
Include in the room welcome packet or print on a card near the TV. Guests connect without calling the front desk. Update per-stay if you rotate passwords.
Display in meeting rooms and common areas. New employees and visitors connect instantly. Use a guest network SSID to keep internal traffic separate.
Project on screen or print on badges and programs. Hundreds of attendees connect without a help desk bottleneck. Generate a fresh code for each event.
Let customers browse while they wait. A small printed sign at the entrance or waiting area does the job. Use a bandwidth-limited guest network to keep business traffic fast.
Most modern routers support a separate guest WiFi network. Create a QR code for the guest network rather than your main network. This way, guests get internet access but cannot see your computers, printers, or NAS drives. You can change or disable the guest network without affecting your own devices.
For reliable scanning, print your QR code at least 2 cm × 2 cm for close-range use (table tents, menu cards) and at least 10 cm × 10 cm for wall signs. The rule of thumb: the scanning distance is roughly 10 times the QR code width. A 3 cm code works from about 30 cm away.
Always scan your QR code with at least two different phones (one iPhone, one Android) before printing 50 copies. Verify that it connects to the correct network and that the password works. Common mistakes: wrong capitalization in the SSID, trailing spaces in the password, or selecting the wrong encryption type.
Download the SVG version if you plan to print. SVG files are vector graphics that stay perfectly sharp at any size, from a business card to a billboard. Use PNG for sharing via messaging apps, email, or embedding in documents.
If your network is set to "hidden" (the SSID is not broadcast), WiFi QR codes still work. The QR code format supports an optional H:true parameter that tells the phone to search for a hidden network with the specified name. Some generators handle this automatically when you check a "hidden network" option. Without this flag, phones may fail to connect to hidden SSIDs even with the correct credentials.
Note: hiding your SSID does not meaningfully improve security. Your network still broadcasts traffic that reveals its presence to anyone with basic tools. If security is a concern, use a strong WPA2/WPA3 password instead.
Yes. iPhones running iOS 11 or later can scan WiFi QR codes with the built-in Camera app. Android phones running Android 10 or later support it natively too. Older Android devices can use any free QR scanner app. When scanned, the phone automatically joins the WiFi network — no manual password entry needed.
A WiFi QR code is as safe as writing your password on a sticky note — anyone who can see or photograph the QR code can extract the password. For home use, this is typically fine since you control who sees it. For businesses, it is ideal for guest networks. Never use a WiFi QR code for a network that has access to sensitive systems. Our generator creates the QR code entirely in your browser, so your password is never sent to any server.
A WiFi QR code encodes three pieces of information: the network name (SSID), the password, and the encryption type (WPA/WPA2, WPA3, WEP, or none). The data follows the standard format: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;. When a phone scans this, it reads the format and auto-connects to the specified network using the embedded credentials.
