Among the most popular conversion formulas are the "Average Color Values" formula, which takes equal amounts of red, green, and blue channels and calculates their average value as "(Red+Green+Blue)/3" for the amount of light left in the image. This tool provides the three most popular grayscale conversion formulas as well as gives you the freedom to create a custom formula. There are also multiple methods for removing the color information from an image. As the information about the amount of color is lost, we obtain a grayscale or a black-and-white image. To create a grayscale image, the tool removes information about how much color is in each of these channels and leaves only information about the amount of light in these channels. These three colors are stored in three separate color channels, called the red color channel, the green color channel, and the blue color channel. By combining various amounts of these three colors together, we get images of all possible colors. As you may know, all colors that you see in images are actually made out of just three primary colors – red, green, and blue. This tool converts color images into grayscale images.
