Wi-Fi QR code generator

Set up your guest code

1. Check the network first. Connect a phone manually with the details you plan to share. Choose a guest network if one is available, and ask the network owner before posting its login.
2. Enter Network name. This is the Wi-Fi name shown in the phone's network list, not your router's model or the name of your business. Copy its spelling, spaces, and capital letters exactly.
3. Match Security to the router. Select WPA for a network using that password security, WEP only if the network actually uses WEP, or None for an open network. Check the router settings or ask its owner if unsure.
4. Enter Password. Use the Wi-Fi joining password, not the password for the router's administration page. For None, the tool leaves the password out.
5. Use a visible network. Hidden networks are not supported by the Wi-Fi form. Use a visible guest network for this code.
6. Download and try joining. Pick PNG or SVG, then scan with a phone that is not already connected. Confirm the network name, accept the joining prompt, and open a web page to check the connection.

A worked example: a guest room

Suppose your guest network is named Garden Guest, uses WPA2, and has the password GardenVisitors42. Enter Garden Guest in Network name, choose WPA, enter that password, and use the Wi-Fi tab for this visible network. These details illustrate the fields; they do not identify a working network. Use your own login. Label the print “Scan to join guest Wi-Fi” and test it in the room where guests will use it.

What the code can and cannot do

The password is stored in the code and can be read by anyone with the image. A QR code does not make a shared password secret. Treat the printed sign like a written login, and avoid posting a private network's code where strangers can photograph it.

This form handles a network name and shared password. It has no fields for a work or school login with a separate username, certificate, or sign-in method. It also cannot bypass a network's welcome page or grant internet access when the router is offline. Follow the network owner's instructions for those cases.

The code is static: its settings cannot be edited after download, and this tool does not count scans. If the network name, password, or security changes, make a new code and replace the old signs. The image has no expiry timer, but old login details will no longer join the changed network.

Print a sign that scans

Use at least 2 cm / 0.8 in for the code's width; make it larger when the pattern is dense. PNG size is the number of pixels in the file, not centimeters on paper. SVG can scale for printing. The tool uses dark squares on a light background. Keep the blank quiet margin around the code. Test one print before printing many.

If a guest cannot connect

If the phone does not recognize the image, try its built-in QR scanner, brighter lighting, and a larger print. If it recognizes the network but joining fails, compare the SSID, security, and password with a successful manual login. Check that the guest is within range. If joining succeeds but websites do not load, check for a welcome page or router connection problem.
