Once you have merged several files into one long document, the lack of page numbers becomes obvious the moment someone needs to say “look at page 14”. Adding sequential numbers after the merge is a quick final polish that makes the whole package professional and easy to reference.
Choosing position and starting number
Common placements are bottom-centre or bottom-right. Top positions work when the bottom margin is already crowded. The starting number can be any integer — useful when the merged file is part of a larger set and needs to continue numbering from a previous section, or when a cover page should not count as page 1.

If you number the individual files first and then merge them, the numbers will restart or conflict. Numbering the final merged document once gives a single continuous sequence and avoids that confusion.
Existing printed numbers
If some pages already contain printed page numbers from the original documents, the new numbers are simply drawn on top. Review the result; in most cases the clean digital numbers are preferable for a newly assembled file.
Privacy
Adding numbers is a light operation, yet the underlying document may be sensitive. A local tool never uploads the file just to stamp a few digits.
