Web

Free online web tools for tasks specific to building and debugging websites: converting colors between HEX, RGB, and HSL with full alpha support, breaking a URL down into its protocol, host, port, path, query parameters, and fragment, building a linear, radial, or conic CSS gradient visually, and turning a URL, WiFi network, or vCard into a scannable QR code. Frontend developers and designers use Color Converter when translating a design system's color tokens between formats a codebase or graphics API expects, URL Parser when inspecting a long or unfamiliar URL — a redirect target, a tracking link, a query string full of parameters — without hand-parsing it, and QR Code Generator when a link needs to move from a screen to something scannable, like a printed flyer or a business card. Like every tool on this site, all four run entirely in the browser: a pasted URL's credentials, a color value, or QR content never leaves your machine.
