It extracts Red, Green and Blue in equal parts. Use only red channel for converting JPG to grayscale. Custom weights used in this example ignore green and blue colors but sets red to maximum. As a result only the red channel controls the amount of gray in the example JPEG graphics file. All jpg tools. Didn't find the tool you were looking for?

This tool converts color images to grayscale images. It removes all information in color channels and only leaves gray color information in the output image. As a result you simply get a black and white image. As there are many ways how to remove color from an image, you can choose the conversion algorithm or enter your own constant weights for how much grayscale to extract from each color channel.
