Add Page Numbers to PDF Online Free

Why add page numbers to a PDF?

Large PDFs without page numbers get confusing fast — especially once they're printed or shared, when there's no way to say "check page 12" or cite a specific section. Numbering fixes that with almost no effort.

Pick a position, a numbering style, and a starting number, and PDFly stamps every page in your browser — no upload, no software, no watermark left behind.

Common uses

Business reports and proposals
Academic theses and dissertations

Best Practices & Limitations

Tips for best results

Start numbering from a page other than 1 if your document has an unnumbered cover or title page.
Bottom-center is the most compatible position for printed documents; bottom-corner works better for double-sided binding.
Re-run the tool with a fresh copy of the original if you need to change the style — numbers aren't editable after saving.

Limitations & when not to use this tool

Doesn't renumber existing page labels used by some PDF readers' navigation panel, only adds visible printed numbers.
Not meant for documents that already contain page numbers in the design — that will produce duplicates.
Skip this if you need chapter-based numbering (like 1-1, 1-2, 2-1) — this tool applies a single continuous sequence.

Frequently asked questions

Can I choose where the numbers appear?

Yes — top or bottom, and left, center, or right. Bottom-center and bottom-right are the most common choices for reports and business documents.

Can I start numbering from something other than 1?

Yes. This is useful when a cover page or introduction should stay unnumbered and the count should start later in the document.

Will this overlap my existing headers or footers?

It can if the position you choose is already in use. If your PDF has its own header/footer content, pick an unused corner for the cleanest result.

Do I need to install anything?

No. Everything runs in your browser tab — no software, no account, no sign-up.
