Can I skip the cover or first page?

Yes. Tick Skip first page, or enter a range such as 3-20 to number only those pages. The starting number controls what the first numbered page shows.

Can I put numbers on the outer edge for double-sided printing?

Yes. Pick a left or right position and enable Mirror on even pages — numbers switch sides on even pages, like a printed book.

Will it change the rest of my PDF?

No. Numbers are drawn on top of each page; existing text, images, links and bookmarks are kept.

Does it work with rotated or landscape pages?

Yes. Page rotation and size are read from each page, so numbers appear upright and in the right place on every page.

Is the Add Page Numbers to PDF free to use?

Yes. Add Page Numbers to PDF is completely free with no sign-up, no watermarks and no usage limits.

Are my files uploaded to a server?

No. Add Page Numbers to PDF runs entirely in your browser — your files and data never leave your device.

Does it work on mobile and offline?

Yes. It works in any modern browser on desktop or mobile, and the toolkit is a PWA that keeps working offline after your first visit.

About the Add Page Numbers to PDF

Add page numbers to a PDF — pick the position, formats like 'Page 1 of 10', starting number, font and margin, skip the cover, with a live preview. Runs in your browser.

Page numbers are drawn with standard PDF fonts (Helvetica, Times or Courier), so they stay crisp at any zoom, print sharply and add almost nothing to the file size. The document is processed with pdf-lib entirely in your browser, which matters for contracts and other files you'd rather not upload.

Add Page Numbers to PDF is part of a free, privacy-first toolkit. Your files are handled entirely in the browser with pdf-lib and PDF.js, so nothing is uploaded to a server and there are no page or size limits.

Because add page numbers to pdf works without any sign-up or installation, you can use it as often as you like and it's always available — on desktop or mobile, and even offline.
