Add Page Numbers to PDF

Stamp a running number on every page of a PDF. Choose where the number sits, which number it starts from, whether it reads as a plain 1, Page 1, 1 / N or Page 1 of N, plus the font size and font. Numbers are added as new text on top of each page, so your original content, links and images stay untouched and the document keeps its selectable text layer. Your file is opened and numbered in the browser and never leaves your device.

How to add page numbers to a PDF

Add your PDF

Drop one PDF into the tool or click to browse. The page count is read on your device, so nothing is uploaded.

Choose the position, the starting number, the format, the font size and the font, and turn on skip first page if the cover should stay blank.

Add and download

Click Add page numbers, wait for the pages to be stamped, then download the numbered PDF to your device.

Why use Aihangsoft Add Page Numbers

Number any layout

Six placements and four number styles cover reports, contracts and manuscripts, whether the number belongs in the middle of the footer or the corner of the header.

Keep the original file

Numbers are drawn as new text on top of each page. The PDF is not rasterized, so text stays selectable, links keep working and photos keep their resolution.

Private by design

Your file is opened and stamped in the browser. Contracts, invoices and IDs are never uploaded, stored or queued on a server.

Page numbering for everyday documents

Stamp a full report

Add a running number to a long document so printed pages stay in order and every section is easy to reference.

Use case: reports, manuals, theses

Start from any number

Continue the numbering of a chapter that follows another file, or set the counter so the printed book starts at the page you need.

Use case: chapters, book parts, continuations

Match a house style

Pick Page 1 of N for formal documents, a bare number for a clean footer, and a serif or mono font to match the rest of the layout.

Use case: contracts, briefs, filings

Leave the cover clean

Skip first page keeps the title page free of numbers while the rest of the document still counts up in sequence.

Use case: covers, title pages, letterheads

Add Page Numbers FAQ

Yes. The numbering runs inside your browser, so your PDF is never uploaded to a server. There is no sign-up, no page limit and no fee, and the page numbers are added without a watermark.
Add your PDF, choose a position such as Bottom center, set the starting number and the format, then click Add page numbers. The numbered file is built on your device and can be downloaded right away.
Yes. Set Skip first page to Yes and the numbering starts on the second page with the number you chose. The cover page is left untouched, and the following pages continue in sequence without a gap.
Four formats are built in: a plain 1, Page 1, 1 / N and Page 1 of N, where N is the total number of pages in the document. Pick the one that fits the document style.
Six positions are available: bottom center, bottom right, bottom left, top center, top right and top left. The margin is fixed at three percent of the page height, so the number keeps the same distance on every page size.
No. The numbers are drawn as new text on top of each existing page, so the original content, links and images stay exactly as they were. The document is not flattened, which means the text layer remains selectable and searchable.
