What is Online Rgba to Hex Converter

The RGBA to HEX Converter is a free online utility that converts RGBA files to HEX color codes.

In CSS, there are several color formats to choose from when defining a color. HEX (Hexadecimal Colors), RGB & RGBA, HSL & HSLA are a few examples. Predefined color names, such as "red, green, blue...", are also available.

HEX and RGBA are the most often used color formats. RGBA stands for "red, green, blue, alpha" and HEX stands for "hexadecimal colors."

The length of a HEX color code can range from one to eight characters without the # sign. The first six characters indicate how much red, green, and blue there is.

Each color is represented by two hexadecimal characters. Each character can be any combination of 0-9 and a-f, giving a total of 16 possibilities. There are 256 options for two characters. The color's alpha is represented by the final two characters of an 8-character HEX code.

If two hexadecimal characters for each color are identical, we can merge them into one hexadecimal character, for example:

  • #ffffffff becomes #ffff.
  • #ffffff becomes #fff.

There are four arguments in the RGBA color format. The first three are red, green, and blue, with values ranging from 0 to 255, while the final is alpha (or opacity), with values ranging from 0 to 1.

If the alpha value is 1, we can ignore it in both HEX and RGBA formats and express it as:

  • #ffffffff is same as #ffffff.
  • rgba(255, 255, 255, 1) is same as rgb(255, 255, 255).
