Color Converter – Convert HEX, RGB, HSL, CMYK & HSV Online
Convert colors between HEX, RGB, RGBA, HSL, HSLA, CMYK, and HSV formats. Type any value and all other formats update instantly. Copy each format with one click.
What Is the Color Converter?
The Color Converter is a free online tool that instantly translates any color value between seven industry-standard formats: HEX, RGB, RGBA, HSL, HSLA, CMYK, and HSV. Whether you are a web developer writing CSS, a graphic designer preparing files for print, or a UI designer working in Figma or Sketch, this tool ensures you always have the exact color code you need in the format your workflow demands. Simply type or paste any value into any field and all other formats update instantly — no page reload, no waiting.
How to Use the Tool
Enter Any Color Value
Type or paste a color into any input field — HEX (#1E88E5), RGB (30, 136, 229), HSL (210, 79%, 51%), or any other supported format. You can also click the color swatch on the left to open a native color picker and choose a color visually.
See All Formats Instantly
Every format field updates simultaneously in real time. The large color preview swatch reflects your chosen color so you can visually confirm it. The tool also displays the nearest named color and whether white or dark text should be used on top of it for accessibility.
Copy & Use Anywhere
Click the copy icon beside any field to copy that specific format to your clipboard. Use HEX in CSS stylesheets, RGBA for transparent overlays, CMYK when sending files to a print house, or HSV for design applications.
Why This Tool Is Useful
Different tools and environments use different color formats. CSS traditionally relies on HEX and RGB. Modern CSS also supports HSL, which is more intuitive for humans. Print design requires CMYK because printers mix four inks (Cyan, Magenta, Yellow, Key/Black). Design applications like Adobe Photoshop and Illustrator often display colors in HSV (Hue, Saturation, Value). Having a single tool that handles all these conversions eliminates manual formula calculations and prevents costly color mismatches between digital and print outputs.
100% free with no sign-up. Open the tool, convert your color, close the tab.
Most converters handle two or three formats. Ours converts all seven industry formats simultaneously.
The tool automatically tells you whether white or dark text achieves better contrast on your chosen color.
Zero latency. All conversions happen in the browser using accurate mathematical algorithms.
Fully responsive. Convert colors on your phone or tablet just as easily as on a desktop.
RGBA and HSLA formats include an alpha (opacity) channel, letting you work with semi-transparent colors.
Frequently Asked Questions
A HEX (hexadecimal) color code is a six-character string preceded by a # symbol (e.g., #1E88E5) that represents red, green, and blue color channels, each with a value from 00 to FF. It is the most widely used color format in web development and CSS stylesheets.
RGB stands for Red, Green, Blue — three color channels with values 0–255. RGBA adds a fourth Alpha channel that controls transparency, ranging from 0 (fully transparent) to 1 (fully opaque). Use RGBA when you need semi-transparent colors in your CSS.
Split the 6-digit HEX string into three pairs. Convert each pair from hexadecimal to decimal: the first pair = Red, second = Green, third = Blue. For example, #1E88E5 → Red: 30, Green: 136, Blue: 229. Our tool does this instantly when you type any HEX value.
HSL stands for Hue, Saturation, Lightness. Hue is the color type (0°–360°), Saturation describes intensity (0%–100%), and Lightness controls brightness (0% = black, 100% = white, 50% = pure color). HSL is considered more intuitive than RGB because it maps closely to how humans think about color.
CMYK (Cyan, Magenta, Yellow, Key/Black) is used for print design. Printers physically mix these four inks. If you are preparing artwork for physical printing, always convert your screen colors to CMYK to ensure what comes out of the printer matches what you see on screen.
Yes. Click the color swatch or the native color picker input at the top of the tool to open your browser's color picker dialog. Choose any color visually and all seven format fields will populate automatically.
Completely free. No account, no subscription, and no limit on how many colors you convert. The tool runs entirely in your browser, so it also works offline once the page has loaded.
