Add PDF Page Numbers
Use Add PDF Page Numbers to stamp page numbers on every page — free, immediate, and with nothing to install. Pages are read and rewritten inside your browser with the PDF-lib engine, so the document never travels to a server and nothing is stored after you close the tab. It is used most by accountants and admin staff preparing invoices, statements and signed contracts. Works comfortably with documents up to roughly 100 MB; larger files depend on the memory your browser has free. Free, unlimited, and free of the upsells most tools of this kind carry.

Frequently asked questions
- Will Add PDF Page Numbers reduce the quality of my pages? — No. Add PDF Page Numbers copies pages at their original resolution and keeps embedded fonts and images untouched, unless you deliberately choose a compression option.
- Does Add PDF Page Numbers upload my document anywhere? — No. Add PDF Page Numbers opens the PDF with JavaScript inside your own browser tab. The file is never sent to a server, which is why it also works with confidential contracts and medical or legal paperwork.
- Can Add PDF Page Numbers open a password-protected PDF? — Not while it is encrypted. Remove the password in the app that created the file first, then the tool can read it normally.
- What is the largest file Add PDF Page Numbers can handle? — There is no hard limit set by us — the practical ceiling is your device's memory. Documents up to about 100 MB are routine; several-hundred-megabyte scans may be slow on an older phone.
