Suppose you have an PDF with 100 pages.
Each page takes has a 99 Kb image and 1 Kb of data.
The total size of such a file would be
(100 x 1 Kb) + 99 Kb = 199 Kb.
Note that the image is stored only once:
it is the same on all pages; no need to duplicate.

Now you split the PDF into 100 pages.
All have 1 Kb of data and an image of 99 Kb.
The size of all these files together is
100 x (1 Kb + 99 Kb) = 10,000 Kb

Amazing, isn't it. An in my sample, I only
talk about an image, I haven't even told you
about embedded fonts and other resources.

This is elementary logic, dear Walter.
