It is part of ToolsMonk's pdf tools collection, so you can finish the job without downloading software, creating an account, or jumping between multiple websites.
This tool is especially useful for workflows such as numbering the pages of a report, contract, or thesis, adding 'page x of y' to a document before printing or binding, and numbering a merged document so pages stay in order. Because it runs directly in your browser, you can use it on desktop, tablet, or mobile while keeping the process fast and easy for one-off tasks as well as repeat work.
Add Page Numbers is also a strong fit for people searching for add page numbers, pdf page numbers, and number pdf pages, because it combines a simple interface with instant results and privacy-friendly processing.

Add Page Numbers is a powerful free online tool available on ToolsMonk that helps you add customizable page numbers to your pdf with flexible positioning and formatting. Whether you're a professional, student, or casual user, our add page numbers provides instant, accurate results right in your browser without requiring any software installation or account creation.
As part of our PDF Tools collection, this tool is designed with simplicity and power in mind. All processing happens client-side, ensuring your data remains completely private and secure. The tool works seamlessly across all modern browsers on desktop, tablet, and mobile devices.
Add Page Numbers stamps customisable page numbers onto a PDF — choose the position, number format, font, size, and colour, and optionally skip the first page when it's a cover.
The format options matter for different documents: a plain number is clean, 'Page X of Y' suits formal reports and contracts because it shows the total length, and 'X/Y' is a compact alternative. Positioning and font controls let the numbers blend with your document's style rather than looking bolted on.
Everything runs locally with pdf-lib, so your PDF — which might be a confidential contract or thesis — is never uploaded, and no watermark is added. Because numbers are applied to the pages as they exist at processing time, it's best to number as the final step, after any merging, splitting, or page removal.
It's part of the ToolsMonk PDF suite, so a typical flow is to merge documents, remove unwanted pages, add page numbers, then compress — all free and in your browser.
Use 'Page X of Y' for formal documents so readers can see the total length at a glance
Skip the first page when it's a cover, so numbering starts on the real content
Add page numbers as the last step, after merging or removing pages, so the count is final
