Add Page Numbers
Add page numbers to your PDF files easily.
What is Add Page Numbers?
Add sequential page numbers to the bottom centre of every PDF page, starting from any number. Free, private, and processed entirely in your browser.
When should you use it?
This tool is useful when you need to add, change, or clean up visible content inside a PDF while staying in your browser.
How Add Page Numbers handles your file
Numbers are drawn onto each page with pdf-lib inside your browser. No upload.
Your device's own CPU does the work, so there is no upload wait and no server-side copy of your document to retain.
Good to know before you convert
- Plain numerals only — the 'Page X of Y' format and custom label styles are not available.
- Placement is fixed at the bottom centre of each page in 10pt grey Helvetica; header placement and left/right alignment are not selectable.
- There is no option to skip a cover page or restrict numbering to a page range.

Frequently Asked Questions
Can I choose where the numbers appear?
Numbers are always placed at the bottom centre of the page. Header placement and left or right alignment are not available in this version.
Can I use the 'Page X of Y' format?
No. The tool writes plain sequential numerals. It does however let you set the starting number, so a document that continues from a previous file can begin at any value.
Can I skip the first page (cover page) when numbering?
Not currently. Every page is numbered. If you need to exclude a cover page, number the document first and then merge it with an unnumbered cover using the Merge PDF tool.
Is my document secure?
Yes. Numbering is applied locally inside your browser and the file is never uploaded.
