Free Online Color Converter — HEX, RGB, HSL & More

OptiDrop's Color Converter lets you pick any color or enter a HEX code and instantly see it in multiple formats: HEX, RGB, RGBA, HSL, and HSLA. Each format can be copied to clipboard with one click. If the color matches a CSS named color (like "blue" or "coral"), the name is displayed.

Color Picker & Manual Input

Use the native browser color picker to visually select a color, or type a HEX code manually for precise values. The alpha slider lets you adjust opacity from 0% (fully transparent) to 100% (fully opaque), which updates the RGBA and HSLA values.

CSS Named Color Matching

If your selected color matches one of the 148 standard CSS named colors (like "steelblue", "tomato", or "gold"), the tool displays the matching name. This is helpful for writing more readable CSS code.

Large Color Preview

A large preview square shows exactly how the color looks, including transparency. All conversions happen instantly in your browser — no data is sent to any server.

Frequently Asked Questions

Enter a HEX color code (like #FF5733) in the HEX input field or use the color picker. The tool instantly displays the equivalent RGB values (e.g., rgb(255, 87, 51)). Each pair of HEX digits represents the Red, Green, and Blue channels in decimal (0-255).
HSL stands for Hue, Saturation, and Lightness. Hue is the color angle on the color wheel (0-360 degrees), saturation is how vivid the color is (0-100%), and lightness is how bright the color is (0-100%). HSL is often more intuitive than RGB because it mirrors how humans think about color.
Click the color picker input to open your browser's native color picker. Select any color visually and the tool instantly converts it to HEX, RGB, RGBA, HSL, and HSLA formats. You can also type a HEX code manually for precise control.
RGB and HEX represent the same colors but in different formats. RGB uses decimal numbers (e.g., rgb(255, 87, 51)) while HEX uses hexadecimal notation (e.g., #FF5733). HEX is more compact and commonly used in CSS and design tools, while RGB is more readable for understanding individual color channels.
