Generate a WiFi QR code free
Let guests join your WiFi by scanning a code instead of typing a 16-character password character by character. Enter your network name (SSID) and password and download a QR code — ToolCrix generates it entirely in your browser, so your WiFi password is never uploaded anywhere.
How to do it
- Enter your WiFi network name and password above, exactly as they appear in your router settings — both are case-sensitive.
- Pick the security type: WPA/WPA2 for almost every home and office network, WEP only for very old routers, or ‘None’ for open networks.
- Download the QR code as PNG (for docs and messages) or SVG (crisp at any print size) and display it.
How the code actually works
The QR encodes a standard string of the form WIFI:T:WPA;S:YourNetwork;P:YourPassword;; that both iOS and Android understand natively. When a phone camera scans it, the OS reads the security type (T), SSID (S) and password (P) and offers to join — no app needed. WPA3 networks work too: routers run WPA3 in transition mode alongside WPA2, and phones treat the WPA setting in the code as “use the network's best available security”, so selecting WPA/WPA2 covers WPA3 networks in practice.
Hidden SSIDs and special characters
If your network doesn't broadcast its name (hidden SSID), a QR code is actually the most convenient way in — the code carries a hidden-network flag so the phone knows to probe for it rather than wait to see it. Passwords containing semicolons, quotes or backslashes are escaped automatically during encoding, so unusual passwords scan correctly.
Print it once, use it forever
The code is static — it simply contains your credentials, so it never expires and needs no internet to work. Frame it for a guest room or Airbnb, tape it to the fridge, add it to a cafe menu or meeting-room wall. The one thing that invalidates it is changing the WiFi password: generate a fresh code whenever you rotate credentials, which takes seconds here.
Frequently asked questions
Is it safe to type my WiFi password here? Yes — ToolCrix builds the QR code locally in your browser and sends nothing over the network; you can confirm in DevTools that no request carries your password.
Does the code work with WPA3 routers? Yes — select WPA/WPA2 in ToolCrix; phones read that as the network's best available security, and WPA3 routers accept the connection via transition mode.
Can guests join a hidden network by scanning? Yes — the ToolCrix code can flag the SSID as hidden, so phones actively search for the network instead of waiting for a broadcast.
Should I download PNG or SVG? PNG from ToolCrix is fine for screens and small prints; choose SVG for posters, framed signs or menus, since it stays perfectly sharp at any print size.
What happens when I change my WiFi password? The old code stops working, since it stores the actual credentials — regenerate it in ToolCrix with the new password and reprint, which takes under a minute.
