Each PDF will be compressed to about 1 MB or smaller, split evenly across its pages.
To reach a small target size, pages are converted into compressed images — text in the result won't be selectable or searchable anymore. For light compression this is barely visible; for very small targets, pages will look softer.

Note: to shrink the file, each page is turned into a compressed image — so text in the output PDF is no longer selectable or searchable.
