One PDF at a time. Adding another file replaces the one in the list.

Numbering

Preview of the stamp: "1"

Numbers are printed in Helvetica, a standard PDF font, so the file opens the same way everywhere. In "Page 3 of 12" style formats, the second number is the last printed number, which changes if you set a different starting number.

How it works

Your browser does the work

When you add a PDF, an open-source library (pdf-lib, MIT licensed, stored on this site) loads and reads the file on your device. It then draws the number you chose at the bottom of each page as real text, in the standard Helvetica font. The rest of each page is left as it was: the numbering does not re-render or compress anything. There is no server involved at any step.

Questions

Are my PDFs uploaded anywhere?

No. The numbers are added in your browser, on your device. There is no server receiving your documents, which you can verify by loading this page, going offline, and numbering a PDF anyway.

Can it open a password-protected PDF?

No. A protected PDF cannot be read without its password, and this tool has no way to ask for one. To use a protected file here, open it in your browser with the password, then use Print and Save as PDF to make an unprotected copy, and add that copy instead.

Can I remove the numbers later?

Not from the saved file. The numbers are drawn onto each page as real text, so keep your original PDF if you might want an unnumbered copy later. This tool never changes the original: it downloads a new file with -numbered at the end of the name.

What does the bottom corners position mean?

It follows the layout of a printed book. Odd pages (1, 3, 5) carry the number at the bottom right and even pages at the bottom left, so the number always sits at the outside edge of the page.
