The conversion uses mathematical formulas to map hue (color angle 0-360°), saturation (intensity 0-100%), and lightness (brightness 0-100%) to red, green, and blue values (0-255 each).

HSL is intuitive: H selects the color, S controls vibrancy, L controls brightness. RGB is how displays work, but HSL is easier for humans to manipulate mentally.

Yes! Use rgb(R, G, B) for solid colors or rgba(R, G, B, A) for transparency. Example: rgb(255, 128, 0) for orange, rgba(255, 128, 0, 0.5) for 50% transparent orange.

HSLA adds alpha transparency to HSL. Example: hsla(30, 100%, 50%, 0.7) is orange at 70% opacity. Alpha ranges from 0 (fully transparent) to 1 (fully opaque).

RGBA adds alpha transparency to RGB. Example: rgba(255, 128, 0, 0.7) is orange at 70% opacity. When converting HSLA to RGBA, alpha passes through unchanged.

Alpha (transparency) is copied directly from HSLA to RGBA without modification. Only the color channels (H, S, L → R, G, B) undergo mathematical conversion.

Use HSL for intuitive color adjustment (creating palettes, adjusting brightness). Use RGB when working with displays, image processing, or APIs that expect RGB values.

In HSL, decrease L for darker shades, increase L for lighter tints. Keep H and S the same to maintain the same hue. In RGB, you'd need to adjust all three values proportionally.

Yes. All conversion happens locally in your browser using JavaScript. No color data is sent to any server.

Currently this tool converts one HSL value at a time. For batch conversion, you can use the sliders to quickly adjust values, or copy and repeat the process for each color in your palette.
