Yes please, I have a very painful process of making individual pictures, shrinking them to fit dA's fussy standards and putting them into a GIF maker...time consuming, man!
ezgif.com/ Enjoy! To shorten them you have to split the gif, download it, then delete the frames you don't want, then re-upload and it'll re-animate it, then just resize, optimise and all that fandango! XD (It drives me most mad when it's like 15.01KB and dA is all "too big. 15KB only." Fiends...)
