Lock the content in place
Form fields and annotations are baked permanently into the page — nobody
can edit or un-fill them afterwards. The document looks identical, your text stays
selectable, and the file usually gets smaller. Right for almost everyone.
Turn every page into a picture
Redraws each page as an image, so nothing at all can be selected, copied
or extracted. Only for when that's specifically what you want — it makes the file much
bigger and the text unsearchable.
