About PDF Page Numbering

Add page numbers to any PDF with full control over position, format, font, color, and starting number. A live preview shows the first page of your first PDF as you adjust settings. Everything runs in your browser — your files are never uploaded.

Common use cases

Reports & theses: number long documents before printing or sharing.
Legal & contracts: add consistent page references.
Booklets: use Roman numerals for front matter and Arabic for the body.

How it works

Upload one or more PDFs and pick a corner position.
Choose a format, font size, color, and starting number.
Click Apply & Download to save the numbered PDFs (as a ZIP if multiple).

Frequently asked questions

Are my PDFs uploaded?

No. Numbering is applied entirely in your browser using pdf-lib — your files never leave your device.

Can I use custom text like “Page 1 of 10”?

Yes. Enable custom syntax and use {n} for the current page and {p} for the total.
