Color Converter
Convert between HEX, RGB and HSL with a live preview and one-click copy.
About this tool
This color converter translates between the three most common color notations β HEX, RGB, and HSL β and shows a live swatch of the result so you can see exactly what you are working with. Whether you need to turn a design spec into CSS-ready HEX or convert an RGB value you received into another form, the tool handles it in one click. Everything runs in your browser, so the color values you enter are never sent to a server.
HEX writes red, green, and blue intensities as hexadecimal in the #RRGGBB form and is the most common notation on the web. RGB expresses the same three channels as decimal numbers from 0 to 255, while HSL describes a color by hue, saturation, and lightness β axes that map more closely to how people perceive color. Since different notations suit different tasks, being able to convert freely makes the work smoother.
Usage is simple: type a value into any one format and the others are computed automatically. Each format has a copy button so you can paste it straight into CSS or a design tool. HSL is especially handy in the fine-tuning stage, when you want to make a color a little lighter or a touch less saturated without changing its overall character.
When picking colors, it helps to keep contrast in mind so text stays comfortably readable against its background. Once you have a palette here, it is worth verifying that the contrast ratio meets accessibility guidelines with a dedicated checker.

FAQ
Are the colors I enter sent to a server?
No. All conversion is calculated in your browser (JavaScript), so the values you enter never leave your device.
Does it support the 3-digit HEX shorthand (#RGB)?
Shorthand like #RGB is normally expanded to #RRGGBB before interpreting. If it is not recognized, try entering the full six-digit form.
When should I use HSL versus RGB?
RGB pairs well with displays and CSS declarations, while HSL is better for intuitive adjustments like changing brightness while keeping the hue. Switch between them as your task requires.
Can it handle transparency (alpha)?
This tool focuses on converting opaque colors (HEX, RGB, HSL). If you need rgba() or 8-digit HEX with transparency, add the alpha component to the converted value.
Can the color shift slightly after converting?
Rounding occurs when converting between RGB and HSL, so a round trip may nudge the last digit slightly. It is not visually noticeable, but if you need exact values, treat your original notation as the reference.
Can I pick colors like a color picker?
The tool centers on entering and editing values directly. By adjusting the numbers while watching the live preview, you can dial in the color you want.
