I'm looking for a way to permanently delete the cropped area in acrobat (batch).
I have a 7 paged document which is cropped into 7 different sizes (news paper adds). I have a batch which does this perfectly, the problem is that each page can be quite big, as all the cropped elements remains in each page. I know I manually can remove these elements, open the pdf in illustrator and remove it or flatten it, but this is not an option.
I have tried using "Remove hidden information", but this removes transparency as well. If I uncheck "deleted or cropped content" there's no transparency error, but the file size won't change much (stay too big). I have tried "preflight fixup" that removes cropped areas, it removes the cropped ares all right but the file size remains unchanged.
In the above you mention that you have tried a "Preflight fixup" that removes the cropped areas and that works but it doesn't reduce the file size, Can I check that you called a "Save As" on the document after that process?
The reason I ask is that "Save" in most PDF viewers just does and incremental save and therefore the file size does not actually get any smaller,, it just removes the references to the objects, not the objects themselves, if you do a "Save As" this will force the PDF to be rebuilt and should remove any objects that are not needed anymore.
