That is a good question, maybe resizing it (scratch that as I just read juliakponsford's comment 😅). Or maybe if you use irfanview to extract the images of the gif, to recompile it with a different program after. Irfanview gave me great size reduction results, and since you can extract all the image from a GIF into a folder, remaking a GIF with those converted images could do wonders. Also Irfanview is free, it you wanna give a shot. Eitherway, I am curious of what you will find to fix your challenge 🙂
