About PDF page number tool

Professional documents — contracts, reports, manuals, and academic submissions — nearly always need page numbers. If you have a PDF that was created or assembled without them, DocumentFlipper makes it easy to add clean page numbers in any position without altering the existing content.

You can place numbers in the header or footer, aligned left, centre, or right. You can also set the starting number, which is useful when the PDF is one chapter of a larger document and numbering should begin at a specific page. Numbers are rendered in a clean, legible font that is consistent across all pages.

The tool adds numbers as a PDF overlay, preserving all original content including hyperlinks, form fields, and annotations. Files are processed securely and deleted within two hours.

Frequently asked questions

Can I choose where the page numbers appear?
Yes. You can place numbers in the header or footer, and align them left, centre, or right.
Can I start numbering from a number other than 1?
Yes. Set any starting number you need, useful when this PDF is part of a larger numbered document.
Will existing header and footer content be overwritten?
The numbers are added as a separate layer and may overlap content that is very close to the page edges. Check the result after adding.
Are hyperlinks and form fields preserved?
Yes. Page numbers are added as an overlay. Existing content, including interactive elements, is not modified.
How long are my files stored?
Your uploaded PDF and the output are automatically deleted from our servers within two hours.
