Choose the right payload
Open the QR Code Generator and select Wi-Fi to share a guest network, or Link or text for a website address, sign, or short message. The code stores the exact payload; it does not point through a JuzhenWork redirect.
Enter Wi-Fi details carefully
Enter the network name exactly as shown on the router or device, including spaces and capitalization. Select WPA/WPA2, WEP, or Open to match the network. Choose Hidden network only when the SSID is not broadcast. A network name can contain at most 32 UTF-8 bytes. WPA/WPA2 passphrases must contain 8 to 63 UTF-8 bytes; WEP accepts only supported legacy key lengths and is outdated, so choose WPA/WPA2 whenever possible. The tool escapes punctuation used by the standard Wi-Fi payload so it is not mistaken for a field separator.
Understand what the image reveals
The Wi-Fi password is encoded inside the QR image itself. It is processed in the current browser tab and is not uploaded by this tool, but anyone who can photograph, copy, or scan the image may be able to join the network. Share the guest-network code only with people who should have access; avoid putting a private home-network password on a public sign.
Scan-test before printing
Generate the code, then scan it with at least one phone that will be used by your visitors. Confirm that the camera recognizes the network or opens the intended link. Wi-Fi QR support varies among camera apps and operating systems. Keep the dark modules on a light background, preserve the white margin, and test the printed size from the distance people will scan it.
Choose an export format
Use PNG for slides, chat, and most screens. Use SVG when the artwork needs to scale for print without becoming pixelated. These are static codes: they have no scan analytics, redirect service, expiry setting, or editable destination. If a URL later changes, create and distribute a new QR image.
