Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.

Add page numbers to any PDF right in your browser — “page / total” at the bottom center of every page, and nothing else changes. Merged reports, scanned contracts and print-bound documents get numbered in one pass, with no uploads.

How it works

  1. Drop files anywhere on the page, click to browse, or paste with ⌘V.
  2. Pick a quality or preset — or set an exact target size and let the tool find it.
  3. Compress, compare before/after, and download — individually or as a ZIP.

Made for merged documents

Numbers matter most right after combining files — a stitched-together report reads like one document once its pages count through. The natural flow is Merge PDF first, then number the result here. The numbering is drawn into each page like any footer; the content above it is untouched.

Where “page X of Y” matters

The “3 / 12” form does more than count — the total is a completeness claim. Anyone holding page 3 of 12 can see that nine pages are missing, which is exactly what several kinds of documents need:

DocumentWhy the numbers matter
Contracts and agreementsX of Y shows no page was added or removed after signing
Court and agency filingsClerks and reviewers cite by page — many portals require it
Print-and-bind handoutsA dropped stack reassembles itself
Merged scan bundlesSeparate receipts and letters read as one countable document

Frequently asked questions

What format do the numbers use?

“3 / 12” — the page and the total, small and gray at the bottom center. Every page gets one, starting from 1.

Will numbers overlap my footer?

They sit in the bottom margin (about 8 mm up). Documents with unusually deep footers could collide — check one page after running; the original file stays untouched either way.

Does numbering change quality or size?

No — it draws a few characters of text per page. The content is not re-encoded and the size change is negligible.

Is it private?

Yes. The document never leaves your browser — nothing is uploaded, and the server only delivers this page. That makes it safe for contracts, invoices, medical records — anything you would not email to a stranger. Want proof? Run one file through, switch your connection off, and run another — it still works.
