Color Converter

HEX ⇄ RGB ⇄ HSL with a live preview — copy CSS-ready values in one click.

Which color format should you use?

  • HEX (#2563eb) — the most common on the web; compact and copy-friendly.
  • RGB (rgb(37, 99, 235)) — same info as HEX, easier to read the individual channels, and required when you need an alpha channel via rgba().
  • HSL (hsl(217, 83%, 53%)) — best for adjusting a color by intuition: change lightness for shades, saturation for vividness, hue to shift the color itself.

Type any format or use the picker — everything stays in sync and the preview updates live. Working on layouts too? The aspect ratio calculator handles sizes for the same projects.

Frequently Asked Questions

How do I convert a HEX color to RGB?

Enter the hex code (like #2563eb) and the RGB, HSL and CSS values update instantly. A hex color encodes red, green and blue as three pairs of hexadecimal digits; this tool does the math for you.

What is the difference between HEX, RGB and HSL?

They describe the same color three ways. HEX and RGB both specify red/green/blue amounts (HEX in base-16, RGB in 0–255). HSL uses hue, saturation and lightness, which is more intuitive for tweaking a color by feel.

Can I pick a color visually?

Yes — use the color picker swatch to choose a color by eye, or type any format. All fields and the preview stay in sync.

What are these values used for?

Web and app design. CSS accepts hex, rgb() and hsl(); designers copy whichever their tool or teammate expects. HSL is especially handy for generating lighter/darker shades of one hue.
