Add Page Numbers to a PDF
Number the pages of any PDF automatically. Each page gets a clean "N / total" label centered at the bottom — perfect for reports, manuscripts, legal filings, and any document where readers need to reference specific pages. You can even start counting from a custom offset when your PDF continues a larger document. Numbering runs locally, so your file never leaves your device.

Verified behavior and practical limits
Last tested:
How it processes your file
A small Helvetica “N / total” label is drawn at the bottom center of each page inside your browser.
Verified behavior
- The default sequence begins at 1 and can start from another positive number.
- Existing page dimensions, text, images, and page order remain unchanged.
- The final label reflects the chosen starting number and document length.
Important limits
- Position, font, color, and “N / total” format are fixed in this version.
- Full-bleed content near the bottom margin can overlap the number, so review the download.
Reproducible example workflow
- Input
- A three-page appendix that follows twelve pages in another file.
- Action
- Set “Start numbering at” to 13 and run Add Page Numbers.
- Expected output
- numbered.pdf labelled 13 / 15, 14 / 15, and 15 / 15.

Frequently asked questions
What format do the page numbers use?
Pages are labeled "N / total" — for example "3 / 12" — centered at the bottom margin. This style makes both the current page and document length immediately clear.
Can I start numbering from a different number?
Yes. Set "Start numbering at" to any positive number. The total count adjusts accordingly, which is ideal for documents split across multiple files.
Will the numbers overlap existing content?
Numbers are placed in the bottom margin area used by most documents. If your PDF has full-bleed content at the very bottom, review the output before sharing.
