Tool QR code generator — Generate scannable QR codes from URLs, text, or WiFi network details with customizable styling options. The tool supports multiple encoding modes, including WiFi networks with security settings, and offers various visual styles such as square or liquid designs with adjustable sizes and colors. Generated codes can be downloaded as PNG images or copied directly to the clipboard.

Claude helped me build this tool for creating QR codes, for both text/URLs and for connecting to WiFi networks.

Screenshot of a QR code generator web form. Heading "QR code generator" with subtitle "Create a scannable code for a URL, text, or WiFi network." A segmented toggle shows "URL / text" and "WiFi" with WiFi selected. Below are fields: "Network name (SSID)" with placeholder "My WiFi"; "Password" with placeholder "Password" and a blue "Show" link; "Security" dropdown set to "WPA / WPA2 / WPA3 (most common)"; an unchecked "Hidden" checkbox; helper text "Not sure? Leave it on WPA / WPA2 / WPA3 — that covers almost every home WiFi network." Below that: "Style" dropdown set to "Square", an unchecked "Border" checkbox, "Size" dropdown set to "Medium", and a "Color" swatch showing black. At the bottom is a blue "Generate QR code" button.
