Tool QR code generator — Generate QR codes from any URL or text with customizable styling options. This tool supports multiple design styles including square and liquid patterns, adjustable sizes, custom colors, and optional borders. The generated QR codes can be downloaded as PNG files or copied directly to your clipboard for immediate use.

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.

This is a beat by Simon Willison, posted on 15th May 2026.
