Color Converter

A color converter translates color values between different CSS color formats — HEX, RGB, RGBA, HSL, and HSLA. Each format represents the same color differently: HEX uses hexadecimal notation (#3b82f6), RGB uses red/green/blue channel values (rgb(59, 130, 246)), and HSL uses hue/saturation/lightness (hsl(217, 91%, 60%)). Designers and developers constantly need to convert between these formats when working across different tools and codebases.

Modern CSS supports multiple color formats, and different contexts favor different ones. HEX codes are compact and ubiquitous in design tools. RGB is intuitive for programmatic color manipulation. HSL makes it easy to create color variations by adjusting lightness or saturation. RGBA and HSLA add alpha channel support for transparency. Understanding and converting between these formats is a daily task in frontend development.

This color converter instantly converts any color input to all major CSS formats simultaneously. It includes a visual color picker, alpha channel slider, live preview with transparency checkerboard, and individual RGB/HSL component values. All conversions happen in your browser — no data is sent anywhere.

1. Enter a color value — Type or paste any color in HEX (#3b82f6), RGB (rgb(59, 130, 246)), RGBA, HSL, or HSLA format. The tool auto-detects the format.
2. Use the color picker — Click the visual color picker to select a color interactively. The selected color updates all format outputs in real time.
3. Adjust the alpha channel — Use the alpha slider to set transparency from 0 (fully transparent) to 1 (fully opaque). The preview shows a checkerboard pattern behind the color to visualize transparency.
4. Copy any format — Each output format (HEX, HEX8, RGB, RGBA, HSL, HSLA, CSS Custom Property) has its own copy button. Click to copy the value you need.

• All major CSS formats — Converts between HEX (3, 4, 6, and 8-digit), RGB, RGBA, HSL, HSLA, and CSS custom property format in one tool.
• Auto-format detection — Paste any color value and the tool automatically detects whether it's HEX, RGB, HSL, or their alpha variants.
• Visual color picker — Interactive native color picker for selecting colors visually when you don't have a specific value in mind.
• Alpha channel support — Full transparency control with HEX8, RGBA, and HSLA output. The preview uses a checkerboard background to visualize transparency.
• Component breakdown — See individual R, G, B, Alpha, Hue, Saturation, and Lightness values for any color at a glance.
• 100% client-side — All color calculations happen in your browser. No server communication, no tracking.

• Design-to-code translation — Convert colors from Figma, Sketch, or Adobe XD (usually HEX) to the CSS format your project uses (RGB, HSL, or custom properties).
• Creating color variations — Use the HSL output to easily create lighter/darker variants by adjusting the lightness value, or desaturated versions by lowering saturation.
• Adding transparency — Convert opaque HEX colors to RGBA or HSLA with a specific alpha value for overlays, backgrounds, and hover states.
• CSS custom properties — Get the space-separated RGB format (e.g., 59 130 246) used with CSS custom properties and Tailwind CSS: rgb(var(--color-primary) / 0.5).
• Accessibility checks — View the exact RGB and HSL components to evaluate contrast ratios and color accessibility compliance.
