Updating large pdf file on multi devices but do I have to download the entire file every time?

So I have a pdf file that is 500mb (already on acrobat.com cloud) and I want to read this across tablet, desktop, and phone. I will be updating this file bit by bit on every one of those devices. Does this mean that every time I want to see the updated version I have to wait for a download of 500mb? Because that is just ridiculous!
