HSL to HSB Converter

About the HSL to HSB Converter

What is HSL to HSB conversion?

HSL and HSB (also called HSV) both start with the same Hue, but they describe the rest of a color differently. HSL uses Saturation and Lightness; HSB uses Saturation and Brightness. They aren't interchangeable — the Saturation numbers usually differ between the two — so you can't just copy the values across. This converter does the math for you and also shows HEX, RGB, and CMYK with a live preview.

You'll want this when a color is defined in CSS-friendly HSL but you need to recreate it in a design app like Photoshop or Figma, which work in HSB. Drag the Hue, Saturation, and Lightness sliders and the HSB equivalent updates instantly. Everything runs in your browser.

How to Use This Tool

1. Set your HSL color. Drag the Hue, Saturation, and Lightness sliders, or type exact values.
2. Read the HSB value. The matching Hue, Saturation, and Brightness appear at the top and update live.
3. Or start from HEX. Paste a HEX code and the HSL sliders snap to match.
4. Take what you need. Copy HSB, HEX, RGB, or CMYK, and explore the shades and harmonies.

Common Use Cases

• CSS to design tools: Bring an HSL color from a stylesheet into Photoshop or Figma's HSB pickers.
• Comparing models: See how the same color reads in HSL versus HSB side by side.
• Tuning a color: Adjust in whichever model feels natural and read the other instantly.
• Learning color theory: Understand why HSL Lightness and HSB Brightness behave differently.

Frequently Asked Questions

Are HSL and HSB the same?

No. They share the Hue, but HSL's Lightness and HSB's Brightness are different scales, and the Saturation values usually differ too. A color that's hsl(0, 100%, 50%) is hsb(0, 100%, 100%) — both pure red, but written very differently.

Is HSB the same as HSV?

Yes. HSB (Brightness) and HSV (Value) are two names for the identical model, so this tool's output works for either.

Why does the Saturation change between HSL and HSB?

Because Saturation is measured relative to a different reference in each model. The conversion accounts for that, which is exactly why a tool is more reliable than guessing.

Is this tool free and private?

Completely. The conversion runs entirely in your browser with JavaScript, so your colors are never uploaded or logged, and it works offline once loaded.
