Add Page Numbers
Insert page numbers anywhere on your PDF pages — bottom-centre, bottom-right, top corners — choosing the start number and format.
How it works
- Pick position, starting number and font size.
- Applies consistently across every page.
Private by design
The file never leaves your device — everything runs inside your browser tab using JavaScript PDF libraries, with nothing uploaded to any server. That also means there's no per-day limit on how many files you process, since nothing is metered on a server.
Good to know
The finished file downloads straight to your device's normal Downloads folder with a new file name, so the original stays untouched and you can tell the two apart at a glance.
Frequently asked questions
Can numbering start from something other than 1?
Yes, set any starting number — useful when this PDF is one part of a larger, already-numbered bundle.
Is there a sign-up or a watermark?
No — no account needed and the output file carries no watermark.
Does it work on mobile?
Yes, it runs in any modern mobile browser on Android or iPhone, not just on desktop.
Is my file kept or deleted after processing?
Neither — it's never uploaded in the first place, so there's nothing stored on any server to delete.
