Color Converter

Convert colors across HEX, RGB, HSL, OKLCH, and related formats. Free online developer tool for fast browser-based work.

What is this tool?

Color Converter translates color values between formats such as HEX, RGB and HSL so frontend work, design handoff and UI QA stay consistent.

How to use

  1. Paste a color value in a supported format.
  2. Convert it to the format needed by CSS, design specs or documentation.
  3. Check the result in the interface where contrast and theme context are visible.

Practical example

A design token may be documented as HEX but implemented as RGB or HSL in CSS.

HEX: #7c6dfa
RGB: rgb(124, 109, 250)
Use case: align CSS variables with design tokens.

Frequently asked questions

What is the difference between HEX and RGB?

HEX is a compact hexadecimal notation. RGB expresses the red, green and blue channels numerically.

Can this check accessibility contrast?

Use conversion as one step, then verify contrast with a dedicated accessibility check.

Why use HSL?

HSL can be easier when adjusting hue, saturation or lightness for UI states.

Limitations / when not to use

Color conversion does not guarantee accessible contrast. Check contrast ratios and visual states separately.
