Convert HEX, RGB, and HSL color values directly in your browser.

The guide and instructions on this page are available while the tool loads.
Color Converter helps developers and designers switch between HEX, RGB, and HSL color formats quickly and accurately.
It is useful for CSS styling, design systems, UI work, branding, frontend development, and visual experimentation.
The tool also includes a live preview so users can see the actual color while copying the exact format they need.
Typical tasks this tool is built for.
Inputs are processed in the browser for a faster workflow.
Practical tips before you download or share the output.
HEX is common for CSS and design tools, RGB is useful for screen-based color values, and HSL is easier for color tuning.
Longer reads that pair well with this tool.

Situations where this workflow saves time.
You can enter a three- or six-digit hexadecimal value in the HEX field, or adjust RGB and HSL values in their separate numeric inputs. The component does not parse CSS rgb(...), hsl(...), or named-color text as input.
It shows normalized HEX, rgb(...), and hsl(...) text, plus a CSS snippet containing those three forms and a --brand-color declaration. All of these values are opaque because no alpha control is implemented.
No. There is no alpha channel in the HEX parser, RGB state, HSL state, picker, copy values, or CSS snippet.
The calculation clamps RGB values to 0 through 255 and HSL saturation and lightness to 0 through 100. The HSL conversion wraps hue for RGB calculation, while the displayed HSL state is constrained to its 0 through 360 range.
The HEX formatter rounds RGB channel numbers before writing two-digit hexadecimal pairs. The RGB and HSL conversion paths otherwise operate on the entered numeric values.
They derive five HSL-based swatches from the current color: the current value, a lighter value, a darker value, a complement, and a lower-saturation lighter soft background. Selecting a swatch applies it as the active color.
It accepts valid HEX foreground and background colors, calculates relative luminance from their RGB channels, and shows the resulting ratio. Its two pass labels use thresholds of 4.5 for normal text and 3 for large text.
The tool calculates the active color’s relative luminance and suggests either #000000 or #ffffff using its built-in threshold. It is a simple suggestion rather than a complete text-accessibility review.
You can copy HEX, RGB, HSL, or the CSS variable through the browser clipboard API. The component does not provide a file or palette download option.
