I am taking PDFs of documents made for printing and reformatting them & compressing them to be downloadable PDFs on our website.
This requires cropping some pages manually using the crop tool. I then use the PDF Optimizer to compress the file into a web suitable file size.
I just realized that cropping a page DOES NOT discard the content outside of the crop. Even after using PDF Optimizer or Reduce File Size, the content outside of the crop still remains. Anyone with Acrobat can remove the crop or change the crop.
I'm trying to create PDFs with the smallest file size possible, so it's silly to keep the content outside of the crop. Is there a way to discard this content?
