🔢 Add Page Numbers to PDF
🔒 Client-Side OnlyWhat Does Adding Page Numbers to a PDF Mean?
Adding page numbers means printing a small number, usually at the bottom or top corner of each page, so readers can track their place and reference specific pages easily. It's one of the simplest formatting touches that makes a long document feel organized and professional, whether it's a report, ebook, thesis, or legal filing.
Page numbers become especially useful once a document is printed or shared as a standalone PDF, where there's no on-screen scroll position to rely on. A quick "Page 12 of 40" at the bottom of a page tells the reader exactly where they are and how much is left.

People add page numbers to PDFs for many different everyday reasons. Some of the most common include:
Academic submissions. Number theses, essays, and reports as required by submission guidelines.
Print-ready documents. Add numbers before printing so loose pages stay in order.
Multi-part contracts. Keep track of lengthy agreements with clear page references during review.

How Your Privacy Is Protected
When you upload a file into the tool above, it is read directly by your browser's own file-reading APIs and processed with JavaScript running on your device. At no point is the file sent across the internet to a remote server or stored in any database. Once you close or refresh the tab, the file and the numbered PDF are simply gone from memory. This local-first design means there's nothing for anyone including NexaTools to access, log, or retain.
Common Problems & Troubleshooting
"Add Page Numbers" stays disabled. This button only activates after a valid PDF has been uploaded.
Numbers appear in the wrong spot. Try a different position from the dropdown some page layouts have content close to certain corners.
Numbering doesn't start where I expected. Double check the "Start numbering at" field it controls the very first page's number.
"This file could not be read." The PDF may be corrupted or password protected. Remove any password and try again.
