Generate and download a Wi-Fi QR code from a network name (SSID) and password — just scan it with your phone's camera to connect
Here is a summary of what each item in the settings panel means and how to choose it. Click to expand.
The name of the Wi-Fi network you want to connect to. It is printed on the router label or shown in its admin screen. Enter uppercase, lowercase, and symbols exactly. Even when it contains special characters, it is safely escaped internally when converted into the QR string.
The Wi-Fi password (encryption key). By default it is shown masked, and the "Show" button reveals it. When the encryption type is set to None, this field is ignored and the code is output as an open network with no password. Note that the generated QR code contains the password as-is, so be careful about who you share it with.
Choose it to match your Wi-Fi's encryption. Most home and business routers use WPA/WPA2 (choose this for WPA3 too, as it is compatible). Choose WEP only if an older device uses WEP. For an open network with no password, choose None.
Check this when connecting to a network configured not to broadcast its SSID (stealth / hidden SSID). In that case H:true is added to the QR string so a compatible device treats it as a hidden network. Normally you can leave it off.
A rough guide to how much of a damaged code can still be recovered (L≈7%, M≈15%, Q≈25%, H≈30%). A higher level is more resistant to damage but adds redundant data and makes the grid more complex. For details on how it works, see the error correction explainer article.
Size is the pixel length of one side of the output PNG image (128-1024). Larger is a good guide for printing, smaller for on-screen display. SVG scales infinitely. Margin is the white border around the code (the quiet zone); the standard recommends 4 or more, and a narrow margin increases the chance of read failures.
PNG can be used directly as an image and is convenient. SVG is a vector format that does not degrade when enlarged, making it ideal for printing, large-format posters, and signage — handy when posting it on a store counter or in a guest room.
A WiFi QR code encodes the network name (SSID), password, and encryption type together in a single QR code. When you scan it with your smartphone's built-in camera or a QR reader app, you can connect to Wi-Fi without typing the password by hand. Printing it and posting it in a store or at home lets you share the network with guests quickly.
Most home and business routers use WPA/WPA2 (choose WPA/WPA2 for WPA3 too, as it is compatible). Choose WEP only if an older device uses WEP. For an open network with no password, choose None; the password field is then ignored and the code is output as T:nopass. Check your router's settings screen to confirm the encryption type.
No, they are not sent. From entering the SSID and password to generating and downloading the QR code, all processing happens entirely within your browser (JavaScript). Your input is never uploaded to a server. Note that the generated QR code contains the password as-is, so be careful about who you share it with.
