Color Converter: HEX, RGB, HSL Online Free Tool

Converting between color formats is a daily task for web developers and designers. Whether you're working with CSS custom properties, adjusting brand colors in Figma, or debugging UI rendering issues — having a reliable color converter saves time and prevents frustration.

Supported Color Formats

Our free online color converter handles all standard web color formats:

• HEX — 6-digit hex code (e.g., #6366f1) used in CSS and design tools
• RGB — Red/Green/Blue values (e.g., rgb(99, 102, 241)) for digital displays
• HSL — Hue/Saturation/Lightness (e.g., hsl(239, 84%, 67%)) for intuitive color adjustments
• HSB/Hue — Hue/Saturation/Brightness used in Figma and Adobe tools

Common Conversion Formulas

Understanding how color conversion works helps when debugging. Here are the key formulas:

HEX to RGB

// #6366f1 → rgb(99, 102, 241)
const hexToRgb = (hex) => {
  const r = parseInt(hex.slice(1, 3), 16);
  const g = parseInt(hex.slice(3, 5), 16);
  const b = parseInt(hex.slice(5, 7), 16);
  return `rgb(${{r}}, ${{g}}, ${{b}})`;
};

RGB to HSL

const rgbToHsl = (r, g, b) => {{
  r /= 255; g /= 255; b /= 255;
  const max = Math.max(r, g, b), min = Math.min(r, g, b);
  let h, s, l = (max + min) / 2;

  if (max === min) {{
    h = s = 0;
  }} else {{
    const d = max - min;
    s = l > 0.5 ? d / (2 - max - min) : d / (max + min);
    switch (max) {{
      case r: h = ((g - b) / d + (g < b ? 6 : 0)) / 6; break;
      case g: h = ((b - r) / d + 2) / 6; break;
      case b: h = ((r - g) / d + 4) / 6; break;
    }}
  }}
  return `hsl(${{Math.round(h * 360)}}, ${{Math.round(s * 100)}}%, ${{Math.round(l * 100)}}%)`;
}};

Best Practices for Color Handling

• Use HEX for production CSS — smallest file size, widely supported
• Use HSL for color manipulation — adjusting lightness/saturation feels natural
• Consider alpha with RGBA/HSLA — for overlays and transparency
• Test in both light and dark modes — some colors look drastically different
