Wi-Fi QR code generator
Turn a network name and password into a QR code that joins Wi-Fi with a camera, no typing required.
Wi-Fi QR code generator
Enter a network name and password and this tool builds the standard WIFI: connection string and renders it as a QR code — the same format printers, routers and guest-network signs use. Point a phone camera at the result and it offers to join the network directly, which saves spelling out a long WPA passphrase to every visitor, houseguest or café customer.
Choose the security type — WPA (also covering WPA2 and WPA3), WEP, or an open network with no password — and mark the network as hidden if it doesn't broadcast its name, which adds the H:true flag a scanner expects. Escaping special characters is on by default: a semicolon, comma, colon, backslash or quote inside the name or password is backslash-escaped so a scanner reads the field boundaries correctly, since those exact characters separate one field from the next. Turn escaping off only when pasting a string that's already escaped.
Error correction, the quiet zone (margin) and the rendered size all affect how reliably a camera locks onto the code — more correction survives a scratched or partly obscured print at the cost of a denser pattern. Pick a foreground and background colour to match a sign or a wallet card; the tool flags colours that are too close in contrast or a light foreground on a dark background, either of which scans unreliably. Switch on "Show the raw WIFI: string" to see exactly what the code encodes before handing it out — and note that the password sits inside it as plain, readable text.
Everything runs locally in your browser: the network name and password are never uploaded anywhere. Copy the connection string, download the code as an SVG or PNG, or print it straight from the page.
