RGB to HEX Converter

Enter the red, green, and blue channels as whole numbers from 0 to 255. The converter maps each decimal channel to a two-digit hexadecimal pair and joins the three pairs after a hash sign.

For example, RGB 255, 87, 51 becomes #FF5733. The live swatch helps confirm the result before you copy it into a stylesheet, component theme, CMS, or design file.

Decimal RGB uses values from 0 through 255. Hexadecimal uses sixteen symbols, 0–9 and A–F, so each channel fits into two characters from 00 through FF. A value of 255 is 15×16 + 15, represented as FF.

The conversion changes notation, not the displayed sRGB color. rgb(59, 130, 246) and #3B82F6 describe the same three channel values in different formats.

Paste the result into properties such as color, background-color, border-color, fill, or stroke. A named design token such as --brand-accent is usually easier to maintain than repeating the literal code across components.

Six-digit HEX does not include transparency. When opacity is part of the requirement, use an eight-digit HEX value or a modern rgb() color with an alpha component and verify support for the target environment.

Each channel must be a whole number between 0 and 255. The controls constrain values to that interval and round decimal input, preventing invalid pairs from entering the generated code.

If the source already gives percentages or a color profile other than sRGB, convert it into sRGB channel values first. This page performs numeric RGB-to-HEX notation conversion; it does not perform print-profile or wide-gamut color management.
