How add page numbers to pdf works

A PDF page numberer overlays a small text label — '1', 'Page 1 of 10', etc. — at a chosen position on every page of a PDF. Unlike server-based tools that upload your file, this tool uses pdf-lib running directly in your browser. We embed Helvetica, compute the text position from your settings, and draw the label on top of each existing page. The underlying page content is not modified — the number is layered on top.

What's inside Add Page Numbers to PDF

100% client-side processing — your PDF never leaves your browser. Six positions: top and bottom × left, center, right. Four formats: '1', '1 / 10', 'Page 1', 'Page 1 of 10'. Custom font size, start number, and edge margin. Helvetica font for cross-reader compatibility. Lossless — original page content is preserved. No watermarks, no ads, no sign-up. Works on mobile and desktop.

Add Page Numbers to PDF workflow

When you drop a PDF, the tool parses it with pdf-lib and shows the page count. You pick a position, format, font size, start number, and margin. On click, the tool embeds the Helvetica standard font, iterates the pages, computes the text width at the chosen size, and uses that to position the label correctly (centered, left-aligned, or right-aligned). The label is drawn on top of the page in dark gray. The finished PDF is re-saved and offered as a download via an in-browser blob URL. Nothing is sent to a server.

Pro tips when you add page numbers to pdf

Bottom-center is the safest default — it matches most existing footers and printing conventions. Use 'Page X of Y' for formal documents; use plain numbers for casual ones. If your PDF already has a footer, pick top-right or top-center to avoid overlap. Set 'Start at' to skip front matter — e.g. start at 1 on page 5 by splitting the PDF first, numbering the body, and merging the front matter back.

Add Page Numbers to PDF — known limits

Cannot skip specific pages — every page gets a number. Cannot use custom fonts or colors beyond dark gray Helvetica. May overlap with existing footers — pick a different position in that case. Strong-password-protected PDFs need to be unlocked first using our PDF Password Remover.

add page numbers to pdf FAQ

Is this PDF page numberer really free?

Yes. No sign-up, no watermark, no limits. Number as many PDFs as you like.

Does it upload my file?

No. Page numbers are drawn locally using pdf-lib. Your file never leaves your browser — verify with DevTools → Network.

Can I start numbering from a number other than 1?

Yes. Set the 'Start at' field to any positive integer. If you set it to 5, the first page becomes 5, second becomes 6, and so on. Useful when your PDF is one chapter of a larger book.

What formats are supported?

Four formats: plain number ('1'), with total ('1 / 10'), 'Page 1', and 'Page 1 of 10'. The 'of N' formats use the total page count of the current document.

Where can I place the numbers?

Six positions: top-left, top-center, top-right, bottom-left, bottom-center, bottom-right. Adjust the margin slider to push the numbers further in or out from the edge.

Will the original content be touched?

No. We only draw text on top of the existing pages — the rest of the page (fonts, images, hyperlinks) is unchanged. The added numbers may overlap with existing footers if your PDF already has them; pick a different position in that case.

Is there a file size limit?

Up to 100MB per file. The numbering itself adds only a tiny amount to the file size.

Can I number only certain pages?

Not yet — every page gets numbered. To exclude pages, use our Split PDF first, number each piece, then Merge them back together.
