Hex to RGB Converter Online Tool

This online Hex to RGB converter tool helps you to convert one Hex color (base 16) into a RGB color (base 10), and test the result color within the website.

the Color System used in HTML is also be written down as Hex number, from #000000 (pure black) to #FFFFFF (pure white). For example, #123456 means the Red is "12" (in range "00" to "FF"), the Green is "34", the Blue is "56". The Hex color system also support 3-digits color, for example, color #e1a is equivalent to #ee11aa.

The RGB color ("R" stands for "Red", "G" stands for "Green", "B" stands for "Blue") is specified how much red, green and blue light are combined together. The syntax is rgb(16,110,190).

1. Step 1: Get the hex number of each sub-color (Red, Green and Blue).

2. Step 2: Convert each hex number into decimal number.

3. Step 3: Write the RGB Color result String in correct syntax.

Example 1: Convert Hex Color "#106ebe" to RGB Color (result is "rgb(16,110,190)"):

Example 2: Convert Hex Color "#ea3" to RGB Color (result is "rgb(238,170,51)"):
