Add Page Numbers to PDF
Stamp page numbers onto a PDF.
Upload a PDF and stamp page numbers onto every page. Choose the position, the starting number and the font size. Everything runs locally in your browser. You can also work on several PDFs at once: add up to 20 files, apply the same settings to all of them, and download the results one by one or together as a ZIP.

Frequently asked questions
Are my files uploaded to a server?
No. PDF processing happens locally in your browser with pdf-lib, so your files never leave your device and nothing is stored.
Where are the numbers placed?
At the bottom of each page — center, left or right, as you choose — using the standard Helvetica font.
Can I process several PDFs at once?
Yes. Add up to 20 PDFs (25 MB each, 150 MB in total). Each one is processed separately in your browser and gets its own download, with "Download all as ZIP" for the whole batch. A file that fails — a password-protected or damaged PDF, for instance — is reported on its own row and does not stop the others.
Is it really free?
Yes — free, with no signup, no watermark and no limits.
