Imagine you're working on a PDF and want to combine several pages from the other file into this PDF file at a specific position. Well, you cannot do this using batch combine. In such cases, UPDF can insert pages into PDF files to meet your requirement.

UPDF will now insert the source PDF into the target PDF file at the specified position with selected pages.
