Color Converter is a 100% free, browser-based utility that enables you to convert hex, rgb, hsl, hsv and cmyk colors. Unlike traditional cloud converters, all processing executes locally on your device with zero server uploads, delivering immediate results and ironclad data privacy.
About the Color Converter
The Color Converter understands every common way of writing a colour: hex codes like #ff8800 or #f80, rgb() and rgba(), hsl() and hsla(), and the 148 named CSS colours such as "tomato" or "rebeccapurple". Type or paste one and it instantly shows the same colour as HEX, RGB, HSL, HSV and CMYK, each ready to copy.
It also calculates the WCAG contrast ratio of the colour against white and black text, so you can see at a glance whether a background colour is accessible for normal or large text.

Frequently asked questions
How do I convert HEX to RGB?
Split the six hex digits into three pairs and convert each pair from base 16 to base 10. For #ff8800, ff = 255, 88 = 136 and 00 = 0, giving rgb(255, 136, 0). This tool does it instantly.
Why is CMYK only an approximation?
Screens mix light (RGB) while printers mix ink (CMYK). The conversion here is the standard mathematical formula; exact print colours depend on the paper, ink and colour profile your printer uses.
What contrast ratio do I need for accessibility?
WCAG 2 level AA requires at least 4.5:1 for normal text and 3:1 for large text (18pt or 14pt bold). Level AAA requires 7:1 for normal text and 4.5:1 for large text.
