How do I add page numbers to a PDF?

Select your PDF file, choose your preferred position (bottom center, bottom right, top, etc.), select the numbering format such as 'Page 1 of N', preview the result, and click 'Download Numbered PDF'.

Can I skip numbering on the first cover page?

Yes! Set 'Start numbering on page' to 2. The first page (cover page) will be left blank with no numbers, and numbering will begin on page 2.

Are my documents kept private when adding page numbers?

Yes. DocumentAlter processes your files 100% locally in your browser memory. No documents are ever uploaded to cloud servers.

Page Numbering FAQs

What happens if my PDF contains mixed landscape and portrait pages?

DocumentAlter dynamically measures the exact width and height of each individual page, ensuring footers and headers are positioned accurately regardless of page orientation.

Does adding page numbers increase the PDF file size?

No! The font definitions and text strings add only a few kilobytes of clean vector data to your PDF.
