Color Converter

Color Converter takes a single color value and translates it between the three formats web designers and developers reach for most: HEX (like #3A7BD5), RGB (like rgb(58, 123, 213)), and HSL (like hsl(215, 63%, 53%)). Type or paste a value into any one field and the other two update instantly, alongside a live swatch that shows exactly what the color looks like on screen. Everything happens in your browser using plain JavaScript math — the conversion runs on your own device, and no color value, project data, or anything else is ever uploaded to a server. You can use the tool offline once the page has loaded, and nothing is logged. The math itself is straightforward but tedious to do by hand: HEX is just RGB written in base-16, so each pair of hex digits maps to a 0-255 channel, while HSL requires converting those RGB channels into hue (0-360 degrees on the color wheel), saturation, and lightness percentages. Doing that repeatedly during a design session is exactly the kind of thing a converter should handle for you. Real uses come up constantly. A front-end developer pulls a HEX code out of a Figma export but needs HSL so they can programmatically darken it by dropping the lightness value. A marketer has an rgb() string from a brand guideline PDF and needs the HEX to paste into an email template. Someone building a CSS gradient wants to nudge only the hue while keeping saturation and lightness fixed — far easier in HSL than juggling three RGB numbers. The one-click copy button drops the formatted value straight onto your clipboard so you can paste it into a stylesheet, a design tool, or a code comment without retyping. A practical tip: work in HSL when you want to build a palette of related shades, because adjusting lightness and saturation on a single hue gives you a consistent tint and shade family that RGB tweaking rarely matches. For anyone who touches color in code or design daily, having accurate three-way conversion a keystroke away removes a small but constant source of friction and copy-paste errors.
