WiFi QR Code Generator
100% private — runs on your device, never uploaded. Works offline once loaded.
Generate a QR code that lets guests join your WiFi by scanning it with their phone camera — no typing the password. Enter your network name, password and encryption type, then download the code as PNG or SVG. Everything is generated in your browser.
What the QR code actually contains
A WiFi QR code encodes a short, standardised text string that phones know how to interpret: WIFI:T:WPA;S:MyNetwork;P:mypassword;;. The T field is the security type (WPA, WEP or nopass), S is the SSID (network name), P is the password, and an optional H:true flags a hidden network. When a phone camera reads this pattern it recognises the WIFI: prefix and offers a one-tap Join network prompt instead of just showing raw text.
This tool builds that string from your inputs and renders it as a scannable code on the fly. Special characters in your SSID or password — semicolons, commas, colons, quotes and backslashes — are automatically escaped with a backslash so the code parses correctly even if your password contains them.
Perfect for guest and cafe WiFi
The classic use is guest access. Instead of reading a long, random router password aloud or writing it on a whiteboard, you print the QR code once and guests scan it to connect in seconds. It is a staple of cafes, restaurants, holiday rentals, waiting rooms and home offices, and it means you can use a genuinely strong password without the friction of everyone typing it by hand.
Because the code is just an image, you can drop it into a printed sign, a table tent, a welcome card, a slide, or a sticker by the router. Downloading the SVG version lets you scale it to any size — from a business card to a poster — without the blurriness you would get from enlarging a small PNG.
Choosing the right encryption setting
The encryption menu must match how your router is actually configured or the scan will fail to connect.
- WPA / WPA2 / WPA3 — the right choice for essentially every modern network; the WiFi standard treats these interchangeably in the QR payload.
- WEP — an obsolete, insecure standard found only on very old hardware; use it only if your router genuinely still runs WEP.
- None — an open network with no password; the password field disappears and the code encodes
nopass. - Hidden network — tick this only if your router does not broadcast its SSID, so the phone knows to search for it by name.
A note on printing and privacy
A WiFi QR code is a convenience, not a secret-keeping device: anyone who can photograph the printed code can join your network, exactly as if they had read the password. For a home or business, consider putting guests on a separate guest network rather than sharing your main WiFi, so a scanned code never exposes your primary devices. On the privacy side, this generator runs completely on your device — your password is turned into a QR image locally and is never uploaded, logged or stored, so it is safe to create codes for even sensitive networks here.
Frequently asked questions
Do I need an app to scan the code?
Usually not. Recent iPhones (iOS 11+) and most Android phones detect WiFi QR codes with the built-in camera app — just point and tap the join prompt. Very old phones may need a dedicated QR scanner.
Can I use it for a hidden network?
Yes. Tick the hidden network option so the code includes the H:true flag, which tells the phone to search for the non-broadcast SSID by name when connecting.
Why should I download the SVG instead of the PNG?
SVG is vector-based, so it stays perfectly sharp at any size — ideal for printing large signs or posters. Use the PNG when you need a ready-to-share image file for screens or documents.
My password has special characters — will it still work?
Yes. Characters like semicolons, colons, commas, quotes and backslashes are automatically escaped in the QR payload so the code encodes and scans correctly.
Is generating the code safe with my real password?
Yes. The entire code is built in your browser with JavaScript; your SSID and password are never sent to a server, logged or stored, and they vanish when you close the tab.
Someone photographed my WiFi QR code — is that a risk?
Anyone with the image can join your network just as if they knew the password. For safety, share a guest network rather than your main one, and regenerate a fresh code if you later change the password.
