Add Page Numbers to PDF — Free, Customizable

Last Updated: April 1, 2026

Last updated: 2026-03-11

You merged 5 PDFs into one 47-page document and now there are no page numbers. Or you need to submit a document with numbered pages but the original does not have them. Adding page numbers after the fact should not require Adobe Acrobat.
