Im already skilled with Aseprite, its my main pixel art software. Im just curious if they are compatible.

If not, what is juiceFX compatible with?

JuiceFX is not a pixel software tool. Is a tool to add animations using pixel displacement/transformations, all by code, nothing manual. All working with layers. You can test the demo. The exported files are .png, gif or single pngs of the animation and they are compatibles to any software
