About the RGB to HSB Converter

What is RGB to HSB conversion?

RGB describes a color as amounts of red, green, and blue light from 0 to 255. HSB — also called HSV — describes the same color as Hue (which color), Saturation (how pure), and Brightness (how much light it gives off). This converter reads your RGB values and returns the matching HSB, along with HEX, HSL, and CMYK and a live preview.

HSB is the model built into design apps like Photoshop, Figma, and GIMP, so converting RGB to HSB lets you dial in the exact same color inside your design file. Move the R, G, and B sliders and the HSB values update instantly. Everything runs in your browser, so nothing you enter leaves your device.

How to Use This Tool

  1. Set your RGB color. Drag the Red, Green, and Blue sliders, type 0–255 values, paste a HEX code, or use the eyedropper.
  2. Read the HSB value. Hue in degrees plus Saturation and Brightness as percentages appear at the top and update live.
  3. Grab the rest. HEX, HSL, and CMYK are listed too, each with a copy button.
  4. Explore. Click any shade, tint, or harmony swatch, and check the contrast panel.

Common Use Cases

  • Matching design tools: Convert a web RGB value to HSB to enter it in Photoshop or Figma.
  • Toning a color: Lower the Saturation while keeping the Hue for a muted version.
  • Building shade scales: Drop the Brightness in even steps for a clean dark-to-light ramp.
  • Understanding a color: The Hue number tells you what an RGB triple really is at a glance.

Frequently Asked Questions

Is HSB the same as HSV?

Yes. HSB (Brightness) and HSV (Value) are two names for the exact same model, so the numbers here work in any program that asks for either. Adobe writes HSB while many code libraries say HSV.

What's the difference between HSB and HSL?

They share the Hue but treat the third value differently. In HSB, full Brightness at full Saturation is the most vivid color. In HSL, full Lightness is always white. HSB maps better onto design software; HSL is native to CSS.

Can I use HSB values in CSS?

Not directly — CSS has no hsb() function. Use the hsl() value this tool also gives you for stylesheets, and keep HSB for design apps and image editors.

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.
