Guest Wi-Fi QR checker and maker

Add a photo of your current Wi-Fi QR and type the real details. See whether they match, which characters guests will misread, and print a correct QR card.

How it works

“The Wi-Fi doesn’t work” is one of the most common guest messages. Often the QR code was made before the password changed, a capital letter or a trailing space slipped in, or a ; or : in the password was not escaped, so the phone reads only half of it.

How to use it: type the network name and password exactly as on the router sticker or admin page, choose the security type, and add a photo or screenshot of the QR you use now. Press Check and make QR. The image is read in your browser with the open-source jsQR library and never uploaded.

You get a field-by-field comparison, warnings for spaces, non-English network names, WEP and easily confused characters, and a new standard WIFI: QR code with a character table guests can read — print it or download the SVG.

iPhone camera (iOS 11+) and most Android camera apps join WIFI: codes directly.
