Wi-Fi QR code

How to make the code

1. Enter the network name (SSID) exactly as it appears, including capital letters. SSIDs are case-sensitive.
2. Choose WPA for compatible personal WPA/WPA2 networks, WEP for old equipment, or Open for a network with no password. WPA3-only and enterprise networks are not supported by this tool.
3. Enter the password, tick Hidden network if the SSID is not broadcast, then test the preview with a phone.
4. Download a PNG for a card or label, or an SVG for print. Place it where guests can scan comfortably.

What is inside the code

The code uses the common Wi-Fi QR format, with the SSID, security type, password, and hidden-network flag encoded as plain text. It is not encrypted and it does not connect to a captive portal or configure enterprise authentication.

Treat a Wi-Fi code like a password

Anyone who can scan or photograph the code can read the credentials and may be able to join the network. Use a guest network for visitors, change the password when a printed code is no longer under your control, and do not post a photo of a private network’s code in a public place. The generated image contains the password, even though this page does not upload or save it.

Limits and good practice

• WPA, WEP, and open networks are supported. Enterprise Wi-Fi (802.1X/EAP), captive portals, and device-specific setup are not.
• Some camera apps handle hidden networks differently. Test with the phones and apps your guests are likely to use.
• If the password changes, the old code still contains the old credential. Print a new code; this page cannot update a code that is already printed.
• The payload is capped at 2,000 UTF-8 bytes. Very long SSIDs or passwords can produce a denser code, so keep the print size generous.
• Keep the four-module quiet zone clear and avoid placing the code over a photograph or pattern.
