Add Page Numbers
Add custom page numbers to every page of a PDF.
or drag and drop · max 50 MB
Add Page Numbers stamps page numbers onto every page of a PDF document directly in your browser. Page numbers are a fundamental navigation aid for any multi-page document that will be printed, shared, or reviewed — they let readers refer to specific pages in conversation, help reviewers cross-reference comments, and are often a formal requirement for legal documents, academic submissions, and business reports. Many PDFs arrive without page numbers — presentation exports, assembled documents, converted files — or with numbers that don't match the final page count after editing. iSavePDF's Add Page Numbers tool uses pdf-lib to stamp numbers onto the pages of your PDF in your chosen position, font size, and format, entirely in your browser. Your file is never uploaded to a server. The tool is free with no account required and no watermark on the output.
Step by step
How to add page numbers on iSavePDF
Open Add Page Numbers on iSavePDF
Visit isavepdf.com/add-page-numbers in any modern browser — Chrome, Edge, Firefox, Safari, or Brave on desktop or mobile. No installation, extension, or account is required.
Upload your PDF
Drag your PDF onto the upload zone or click to browse your device. The tool accepts a single PDF of up to 50 MB. A preview of the first page appears so you can see where the numbers will be placed before applying.
Choose number position and format
Select where the page number appears — bottom centre, bottom right, bottom left, top centre, top right, or top left. Choose the number format: plain numbers (1, 2, 3), Page X of Y format (Page 1 of 24), or Roman numerals. Set the starting number if you want the sequence to begin at a value other than 1 — useful when the PDF is one chapter of a larger document.
Set font size and offset
Adjust the font size to match the document's typography, and set the margin offset to ensure the number doesn't overlap the existing content near the page edge. The live preview updates so you can verify placement before converting.
Apply and download
Click Add Numbers. pdf-lib stamps the number onto each page at the specified position in your browser's memory and saves the result to your downloads folder. No upload occurs.

When to use it
Common use cases
Adding page numbers before submitting legal or academic documents
Courts, law firms, and academic institutions frequently require that submitted documents have page numbers. A contract, a brief, a dissertation, or a research paper assembled in parts often arrives without consistent page numbering. Adding page numbers before submission ensures compliance with the formatting requirements and makes it easy for reviewers to reference specific pages in their notes and correspondence.
Numbering assembled reports and presentations
PDFs assembled from multiple sources — a slide deck merged with appendices, a report combined with supporting data tables — often lack consistent page numbers. Adding them after assembly gives the combined document proper navigation. The 'Page X of Y' format is particularly useful for long reports where readers want to know how far through the document they are.
Renumbering after editing
When pages are added, removed, or reordered in a PDF, the existing page numbers (if any) become wrong. Stripping the old numbers and adding new ones that reflect the current page count is the correct fix. Use iSavePDF's Delete PDF Pages, Extract PDF Pages, or Reorder PDF Pages to make the structural edits first, then use Add Page Numbers to apply a fresh, accurate numbering sequence.
Preparing print-ready documents
Documents that will be printed and physically distributed — handbooks, training materials, meeting agendas, reference guides — need page numbers so readers can navigate and discuss specific sections. Adding page numbers as the final step before printing ensures the sequence is accurate and positioned consistently on every page.
Why iSavePDF
The privacy-first way to add page numbers
Most online page number tools require uploading your PDF to a remote server. For documents that are being prepared for legal submission, academic review, or professional distribution, that upload is an unnecessary exposure of content that may be confidential or subject to professional privilege. The document is going to have your name on it in court or before a committee — it should be processed on your device, not someone else's server.
iSavePDF adds page numbers entirely in your browser using pdf-lib. The PDF is read from your local storage, the numbers are stamped onto each page in your browser's memory, and the result is saved to your downloads folder. No data is transmitted to any server. The tool is free and supported by display advertising.
Tips & limits
Tips for the best results
Set the starting number for chapter PDFs
If the PDF is one section of a larger document and needs to continue a numbering sequence from a previous section, set the starting number to match the correct page number in the full document. For example, if your section starts at page 47 of the full report, set the starting number to 47.
Use 'Page X of Y' for reports shared externally
The 'Page X of Y' format (e.g. 'Page 3 of 24') gives readers instant context about where they are in the document without needing to flip to the last page to count. It's particularly useful for documents emailed to clients or stakeholders who may read them on a phone and benefit from knowing how much remains.
Check placement on the last page
The preview shows the first page, but check that the number position doesn't overlap existing footers or content on other pages — particularly if the document has a cover page, a table of contents, or pages with different layouts. Use the 'skip first page' option if the cover page should not be numbered.
Stamp page numbers last in your editing sequence
Add page numbers as the final step after all structural edits (merging, splitting, deleting, reordering) are complete. Numbering before editing means the numbers won't reflect the final page count.
