About this add page numbers to pdf
Put page numbers on a PDF that does not have them. Every page gets a label in the form 3 / 12 — the page and the total — set in 10-point black and centred near the bottom. It is what a printed submission, a contract or a bound report usually needs before it goes out, and it is written into the document rather than added by a viewer. The file is rewritten in your browser and never uploaded, which matters when the thing being numbered is an agreement or an application.
How the add page numbers to pdf works
The total page count is read first, then each page receives a label reading its own number over that total, drawn in 10-point black type centred near the bottom of its crop box. The label is drawn onto the page, not inserted as a header field, so it sits on top of whatever is already there. On a page whose content reaches the bottom margin the two can overlap.

Limitations & privacy
One PDF up to 20 MB and 200 pages. Crop boxes must be at least 100 × 60 points. Numbering always starts at 1 and runs to the end — there is no option to start from a different number, skip a cover page, or change the position, size or format of the label. Labels can overlap existing content near the bottom of a page, and rotated pages keep their original coordinate orientation, so a label on a rotated page may not sit where you expect. Encrypted PDFs cannot be opened, and rewriting invalidates digital signatures.

Add Page Numbers to PDF: frequently asked questions
How do I add page numbers to a PDF?
Choose the file and download the result. Each page is labelled with its number over the total, as 1 / 12, centred near the bottom.
Can I start numbering from a page other than the first?
No. Numbering runs from 1 to the last page. Skipping a cover page or starting at a different number is not supported.
Can I move the numbers or change how they look?
No. The label is fixed at 10-point black, centred near the bottom of each page. Position, size and format are not adjustable.
Will the number overlap my content?
It can. The label is drawn on top of the page, so content reaching the bottom margin may sit underneath it. Check the downloaded file.
What happens on rotated pages?
Rotated pages keep their original coordinate orientation, so the label may not appear where you expect. Rotate first, then number.
Is my PDF uploaded?
No. It is read and rewritten by a worker in your browser.
