Color Code Converter

Free Color Code Converter — All Formats

Convert a color between every notation in use on the web, in print and in app code. Paste HEX, RGB, HSL, HSV/HSB, HWB, CMYK, CIE LAB, LCH, OKLab, OKLCH, CIE XYZ, a CSS color name, a 0x literal or a decimal integer, and every other format is produced at once. The converter runs entirely in your browser — nothing is sent to a server.

Formats it reads

Hex in 3, 4, 6 and 8 digits (#39f, #3b82f6, #3b82f6cc); both the legacy comma syntax and the modern space syntax with a slashed alpha (rgb(59 130 246 / 50%)); hue in deg, rad, grad or turn; percentages or plain numbers for channels; all 148 CSS named colors including rebeccapurple; and the transparent keyword.

Formats it writes

• CSS & web — HEX, short HEX, 8-digit HEX with alpha, RGB, RGBA, modern RGB, HSL, HSLA, HWB, and the CSS color name when there is an exact one.
• Perceptual & print — HSV/HSB, CMYK, CIE LAB, CIE LCH, OKLab, OKLCH and CIE XYZ.
• Numeric — decimal integer, hex literal, Android ARGB, percentage RGB and normalised 0–1 RGB.
• Code — CSS custom property, Tailwind arbitrary value and nearest Tailwind class, SwiftUI, UIKit, Android/Kotlin, Flutter, .NET, Java AWT, a Python tuple and a GLSL vec4.

How to Use

1. Paste or type a color code into the box — it converts as you type.
2. Check the “Read as” line to confirm which notation was recognised.
3. Drag the alpha slider if you need a translucent variant.
4. Click any row to copy that single value, or use Copy all or JSON to take everything.

Notes on accuracy

LAB, LCH and XYZ use a D65 white point, matching CSS. LAB, LCH, OKLab and OKLCH can describe colors that no sRGB screen can display; when you enter one, it is clipped into sRGB and the tool tells you so. CMYK is a naive device conversion, not an ICC-managed one — use your print provider's profile for production work. A bare string of 3 or 6 hex characters is read as hex even when it is all digits, so the unambiguous way to enter a decimal is dec(255).
