I have a PDF that is used as readings for a test. We want the students to actually read the content and not search keywords in the text to quickly get to the answers.
I know that I can change the PDF to images, but i worry that this will decrease print quality and increase file size.
I see there is a way to remove copy from a PDF in the security section, but can't see how to make a PDF non-searchable.
Ideally I would like the make the text non searchable, but store the text/fonts as it is.
With Acrobat Pro and the Preflight Tool you can convert the fonts to outlines. This will also increase the file size.
