Every time I open a PDF file that has not already been converted to editable text and images, Acrobat immediately begins the process when I open the file.
I have cut apart many of my books and scanned them to pdf, and some of them are quite large. Not only does automatic conversion take time that I don't have, it doesn't always do the best job.
How do I stop this?
As per the description mentioned above, you want OCR to not run automatically when trying to edit a scanned file in Acrobat, is that correct?

Let me know if that is not the case.
