Extraction is the process of reusing selected pages of one PDF in a different PDF. Extracted pages contain not only the content but also all form fields, comments, and links associated with the original page content.
You can leave the extracted pages in the original document or remove them during the extraction process—comparable to the familiar processes of cutting-and-pasting or copying-and-pasting, but on the page level.
To remove the extracted pages from the original document, select Delete Pages After Extracting.
To create a single-page PDF for each extracted page, select Extract Pages As Separate Files.
To leave the original pages in the document and create a single PDF that includes all of the extracted pages, leave both check boxes deselected.
The extracted pages are placed in a new document named Pages From [original document name]-[n].
