Why ComicSlice?

Hi, I'm Elijah Joseph—comic creator and marketer. I write both vertical and traditional comics (check them out at heyycomics.com). Getting my work onto every webcomic platform meant battling different upload specs and tedious manual scrolling conversions. So I built ComicSlice to make it effortless. I hope you love it as much as I do!
