Choose a fileFusionPDF adds page numbers to any PDF using pdf-lib, entirely in your browser. Choose header or footer position, left, center, or right alignment, font size, and the number to start from. Works on any PDF, any number of pages. No upload, no account, instant download.
Drop your PDF into the upload area. Once loaded, the options panel appears with all numbering settings. Choose your format, set the position and alignment, pick a font size and color, and set the starting number. Click Number and download. The numbered PDF downloads in seconds, with page numbers stamped as crisp vector text on every page.
Page numbers can appear in six positions on the page. Footer positions (bottom left, center, right) are the most common choice for most documents, as readers expect numbers at the bottom. Header positions (top left, center, right) are used when the footer is reserved for other content, such as a company name or a copyright notice stamped with the Header and Footer tool.
Left-aligned numbers work well in books and bound documents where the binding covers the inner margin. Right-aligned numbers are standard in single-sided printing. Centered numbers are the most universal choice and the default setting. All six positions can be fine-tuned with the edge margin control, which sets the distance between the page edge and the number text in points.
The starting number option is useful when a document is one section of a larger work. If you have a 200-page report split into five separate PDF files, each section needs to start where the previous one ended. Setting the starting number to 43 on a 20-page section, for example, produces pages numbered 43 through 62, ready to merge into the full report with continuous numbering.
Custom formats extend this further. Using the custom format field, you can write any template with {n} for the current page and {total} for the total page count. "Section 3, Page {n}" or "Draft — {n} of {total}" are both valid. This covers most professional and academic requirements without needing a separate tool.
Academic papers submitted to journals or universities almost always require page numbers in a specific position. Legal documents, court filings, and contracts are easier to reference in disputes or negotiations when pages are numbered. Internal reports assembled from multiple team contributions need numbering to be navigable in meetings. Presentation handouts printed for attendees benefit from numbers so presenters can say "turn to page 4."
Technical manuals and product documentation are another common case. A 60-page installation guide distributed as a PDF is nearly unusable in support calls without page numbers. Adding them takes under a minute with this tool.
The Page Numbers tool is focused: it adds numbering only, with control over format, position, and starting number. If your need is simply "stamp a number on each page," this is the right tool. It's faster to configure and produces a clean result.
The Header and Footer tool is the right choice when you need to add text other than a page number: a company name, a document title, a "CONFIDENTIAL" label, a preparation date, or a combination of these across both the header and footer zones. It also supports dynamic fields like {n} and {total}, so you can include page numbers as part of a larger text string, such as "Acme Corp — Page {n} of {total}."
