- Why would I convert HSL to RGB?
- Some environments and libraries expect RGB values: canvas APIs, image processing libraries, older design tools, and certain CSS-in-JS setups. Converting from HSL (where you often design) to RGB (where you sometimes need to deliver) is a common workflow step.
- Does this only accept HSL input?
- No. The input accepts any CSS color format: HSL, HSLA, HEX, RGB, RGBA, or a named color. All six output formats are shown at once so you can copy whichever you need.
- What is the valid input format for HSL?
- Type a standard CSS HSL value such as hsl(239, 84%, 67%). Hue is a number from 0 to 360, saturation and lightness are percentages from 0% to 100%. HSLA with an alpha value like hsla(239, 84%, 67%, 0.5) is also supported.
- Does it support transparency?
- Yes. Enter an hsla() value with an alpha channel and the tool outputs RGBA and 8-digit HEX alongside the standard formats. The color preview uses a checkerboard background to show transparency.
