🔢Add Page Numbers to PDF — More Options Than You'd Expect

Adding page numbers to a PDF sounds simple until you actually need to do it a specific way. The cover page shouldn't have a number. The numbering should start at 7 because the first six pages live in a separate document. The numbers should sit bottom right, not bottom center. You need it to say "Page 3 of 18" not just "3." These are all real requirements that come up constantly, and most tools handle maybe two of them if you're lucky.

This tool handles all of it. You get six position options across top and bottom, four number formats including "Page N of Total," a custom prefix field for things like chapter labels, adjustable font size, colour picker, configurable starting number, a skip field for cover and intro pages, and margin control. It all runs in your browser using pdf-lib — a proper PDF manipulation library that draws the numbers as native text on each page without touching anything else in the document.

Because it uses pdf-lib rather than a render-and-rebuild approach, the output is still a proper text-based PDF. All your original text stays selectable and searchable. The file size barely increases. The formatting is exactly as it was. The page numbers are just added on top as a new text element on each page.

📋How to Add Page Numbers to a PDF

🔬Number Formats — Which One to Use

For most office documents and reports, "Page N of Total" is the clearest choice — readers can see at a glance how far through the document they are. For academic submissions, plain numbers are usually the required format. For multi-part documents where you're stitching sections together, the custom prefix lets you add context to each number.

👥Situations Where This Gets Used Every Day

• Reports and proposals: You've got a 30-page business report that needs page numbers before it goes to the client. The cover shouldn't have a number. Set skip to 1, format to "Page N of Total," position to bottom center — done in 20 seconds.
• Multi-part documents: You're assembling a document from several separate PDFs. Part 2 starts at page 14 because Part 1 was 13 pages. Set the starting number to 14 and the numbering continues seamlessly across the merged document.
• Contracts and legal documents: Legal submissions often need numbered pages in a specific format and position. Bottom right is standard for contracts. "Page N of Total" tells the reader and any court exactly where each page sits in the full document.
• Academic theses: The title page, abstract, and table of contents are often unnumbered or use Roman numerals in a separate section. Set skip pages to handle the intro, then apply plain Arabic numbers from where the body starts.
• Technical manuals: A user manual that needs section-aware numbering. Use the custom prefix to add "Section 3 — " before each number so readers navigating a printed copy know exactly where they are.
