Add page numbers to a PDF
Processed on this device. Nothing is uploaded.
Open your PDF, choose where the numbers go and what format to use, and they are added as real embedded text — so they stay selectable and searchable in any reader.
Doing more than one thing?
The full editor puts every operation in one workspace with undo, so you are not exporting and re-opening between each step. Same engine, same privacy, still nothing uploaded.
Why this one does not upload your file
Almost every free add page numbers to a pdf tool works by sending your document to a server, doing the work there, and sending a result back. That is a cost decision rather than a privacy one — server time costs money, which is why those tools meter you, ask for an account, or cap your file size.
This one runs the same work in your browser using JavaScript, so your file never travels anywhere. There is no upload step, no queue, no account, and no page limit — and the page keeps working if you disconnect from the internet partway through.
You do not have to take that on trust. Open your browser's network tab and watch while you work, or read how it works.
What happens to your file
- It is read from your disk into this tab's memory
- Every change happens on your own processor
- The result is built in memory, reopened and checked before you are offered it
- Your original file is never modified
- Closing the tab releases everything — nothing is stored
