Quick answer: Open the Add Page Numbers tool, choose where the numbers go (e.g. bottom-center), pick the format and starting number, and click apply. You don't need Adobe Acrobat or any software — it runs free in your browser, and your file is never uploaded.

Can I add page numbers without Adobe Acrobat?

Yes. Adobe Acrobat Pro is paid software, but you don't need it just to paginate a document. A browser-based tool adds page numbers to your PDF for free, with no install and no subscription — and because everything runs locally, your document stays private.

Formatting options that matter

Position: bottom-center is the most common; corners work well for reports.
Format: plain numbers, "Page X of Y", or Roman numerals for front matter.
Starting number & range: skip a cover page by starting on page 2, or number only a section.
Font & size: match your document's typography for a clean look.

Is it private to add page numbers online?

With CustomizedPDF, yes — the tool stamps the numbers in your browser and never uploads your file. That matters for contracts, legal bundles, and financial reports. Learn how we keep your files on your device.
