Color Picker & Converter – HEX, RGB, HSL

About this tool

The Color Picker & Converter is an essential utility for web designers, UI/UX developers, and brand managers who need to maintain consistent color values across different formats and contexts. When building websites or applications, CSS properties can accept colors in multiple formats — HEX codes for shorthand declarations, RGB values for precise channel control, and HSL for intuitive hue-based adjustments. This tool bridges the gap between these representations, letting you start with any format and instantly see the equivalent in all others.

Frontend developers frequently encounter color values in different formats depending on the tools they use. Design software like Figma and Sketch typically exports colors as HEX or RGB, while CSS animations and gradient definitions often work more naturally with HSL. Rather than manually calculating conversions or switching between multiple online tools, this converter unifies everything in one place. The large preview swatch gives you immediate visual feedback, confirming the color is exactly what you expect. The picker opens your browser's native color chooser; there is no screen eyedropper or image upload. Each format includes a dedicated Copy button, so you can grab the representation you need — whether that is a HEX code for a CSS file, an RGB value for an HTML canvas context, or an HSL declaration for a Tailwind configuration. All processing happens locally in your browser, so your color data never leaves your device.

Design work rarely stops at one format. If the palette lives in a JSON design-token file, format JSON design tokens with our JSON Formatter & Validator before editing the values. When a CSS change needs review, compare the old and new CSS values with our Text Diff Checker. For layout work around a palette, measure the angle in a design with our online protractor. To publish a palette guide, convert the palette guide from Markdown to HTML with our Markdown to HTML Converter.
