How can I copy bookmarks or replace all the pages from one document to another in a PDF file using Foxit Reader?
You can't do that since Foxit Reader is practically a viewer application. It allows you to to view PDF files with minimum features. To modify the PDF, another application is required. The Foxit developers have another software called: PhantomPDF Standard 7. It's not free, but this has the power and features available for editing.
