doPDF permit links and/or images in its PDF files. Files PDf's protection is allowed ?
Does doPDF permit links and/or images in its PDF files ?.
Yes, images are converted in the pdf file (I think that's what you're asking). Links are converted too, if they're in a visible format (not hidden links) like http://www.novapdf.com for example (but novaPDF with a hidden link won't be converted).
Is Files PDf's protection allowed?
No, doPDF doesn't protect the PDF file.
