About Add Page Numbers
Add Page Numbers writes a number onto the pages you choose. You can set the corner, margin, size, color, starting number, and a prefix or suffix, including a Page n of N style. The same placement rules are used for the position preview and the saved file, including landscape and rotated pages.
How to use Add Page Numbers
- Choose a PDF.
- Pick a corner, style, starting number, and margin. Skip the first page or limit the range if you need to.
- Check the position preview, then select Number pages.
- Download the PDF. The original page count is unchanged.
Examples
Skip a cover
Turn on Skip the first page so the cover stays blank and page 2 starts at 1.
Page n of N
Choose Page n of N. N is the number of pages in the file, not only the pages that receive a number.
Limitations
- Text is Helvetica. Emoji and most non-Latin scripts are rejected.
- An existing digital signature will no longer verify after the file is modified.
- Encrypted PDFs must be unlocked first.
- The position preview is a letter-sized schematic of the corner and margin. Each real page uses its own size and rotation.

Frequently asked questions
Are my PDFs uploaded to a server?
No. The file is read and processed by JavaScript running in your browser tab. Utilhex never receives the document, and closing the tab discards it.
Can I use password-protected PDFs?
Not yet. Encrypted PDFs are detected and rejected with an explanation instead of producing a broken file. Remove the password in the application you used to protect it, then try again.
Does “of N” count only numbered pages?
No. N is the page count of the document. Pages you skip are still part of that count, and they do not consume a number.
