This online utility lets you create grayscale GIF animations. It removes colors from a GIF by applying the light intensity extraction formula that averages the intensities in RGB color channels and converts them into gray tones. If needed, you can set custom weights for the red, blue, and green channels via the custom grayscale mode. The monochromatic output GIFs can be viewed in the built-in canvas animator in the browser, as well as downloaded to your computer. Created by GIF experts from team Browserling.

This is a browser-based program that converts color GIFs into grayscale GIFs. It replaces color pixels in all frames with shades of black and white. In color animations, each pixel carries information about red, green, and blue colors but in grayscale animations, each pixel carries information only about the amount of light (or intensity of light). The maximum color intensity produces bright white light and the minimum intensity the darkest black. In the absence of color, the human eyes become more sensitive to details and often it's useful to view your animation in just gray tones. Such grayscale GIF processing emphasizes the texture, shape, and shadow outlines, and viewers' attention falls on the tiniest object details in the animation. By default, the color conversion to monochrome intensities is calculated using the formula I = ⅓R + ⅓G + ⅓B. There are also many other grayscale conversion formulas and standards. For example, for HDTV, a different set of coefficients is used: I = 0.21×R + 0.72×G + 0.07×B, and for HDR television, the formula is: I = 0.26×R + 0.68×G + 0.06×B. You can create a grayscale animation using any red, blue, and green color coefficients by selecting the custom color coefficient mode. The coefficients can be applied to both animated and static GIFs, and you can immediately see the result in the preview canvas. You can turn the animation canvas on and off in the options, and download the grayscale version of your GIF by clicking a button below the output canvas. Gifabulous!

In this example, we convert a rotating color animation of a rainbow into a grayscale rainbow. Each color component has a different brightness level, so we average all of them to a single shade of gray by using the (R + G + B)/3 formula. (Source: Pexels.)
In this example, we use the grayscale effect to create a retro animation. We apply a custom grayscale formula 0.4×R + 0.6×G + 0.1×B to all pixels in all GIF frames. This formula makes the blue color the darkest as the coefficient before B is 0.1 (which means leave just 10% of the original intensity of the blue color). The output GIF of flying birds gives an impression that it was filmed a long time ago. (Source: Pexels.)
This example uses the high definition television (HDTV) standard formula to create a monochromatic GIF of a 3D surface projection. The HDTV model uses different color coefficients: 0.2126×R + 0.7152×G + 0.0722×B that prioritize the green color and almost ignore the blue color. (Source: Pexels.)
