Reports and dissertations
Merge the chapters, sort them, then number the result — in the same screen, without exporting in between.

Numbering is the last step, and that is the problem
Page numbers are almost never added to a finished document. They come after merging chapters, after dropping a draft page, after putting the annexes in the right order — which is exactly when a tool that processes on a server makes you upload the file one more time.
Documents with a cover
Leave the cover unnumbered and start counting from it, the way academic formatting asks.
Scanned pages
Scans often arrive rotated. The number still lands on the footer you see, not on the side of the sheet.
How to number the pages of a PDF
- 1
Open the document
Drop the PDF anywhere on this page, or use the button. The pages appear as thumbnails.
- 2
Choose the format and the corner
Plain number, "3 / 12" or "Page 3 of 12"; six positions; the starting number; and whether the cover is numbered.
- 3
Check and download
Each thumbnail shows the number it will carry. Export when the sequence looks right.
What this tool does differently
The document is not uploaded
The numbers are written into the file inside the tab. Nothing travels over the network, and you can check it in the browser network panel.
Rotated pages come out right
On a page turned 90°, the number still sits on the footer you see and reads upright — not sideways along the edge of the sheet.
The count follows your order
Reorder or delete pages first and the numbering follows. Deleted pages do not take a number and do not count.
Start wherever you need
Continuing a volume that ended at 48? Start at 49. The total adjusts with it.
Preview on every page
The thumbnail shows the corner and the text before the export, so you do not download twice to check.
No watermark
The exported file gets the numbers and nothing else — no stamp, no footer, no advertising page.
Why the file stays with you
Numbering is a trivial change to a document that often is not trivial at all: a contract, a court filing, a dissertation. There is no reason for it to travel.
Local processing
Reading the PDF, drawing the numbers and assembling the final file all happen in JavaScript, inside the tab.
No storage
There is no server keeping a copy, because there is no upload. Close the tab and everything leaves memory.
No account
No sign-up, no email, no daily limit tied to a login.
Frequently asked questions
Can I leave the cover without a number?
Yes. Tick "leave the cover unnumbered" and the first page comes out clean while still counting — so page two shows 2, not 1. That is the usual academic rule.
Does it remove numbers the document already has?
No, and this is worth knowing before you start. Numbers printed into the original are part of the page content, like any other text; our numbering is added on top. If the document already carries numbers in the same corner, the two will overlap — choose a different corner, or use a document without them.
Does it work on rotated pages?
Yes. The position is calculated on the page as the reader sees it, so the number lands on the visible footer and reads upright even when the sheet is turned 90 or 270 degrees.
Can I choose the font?
Not yet. The numbering uses Helvetica, one of the fonts every PDF reader already has, which keeps the file from growing. It covers the Latin alphabet with accents; alphabets such as Cyrillic, Greek or Chinese are not supported in the numbering text.
Can I number after merging several files?
Yes, and that is the point of doing it here. Merge, reorder, delete what is left over and number — all in the same screen, without exporting and re-uploading between steps.
Is the file uploaded to a server?
No. Open the network panel (F12) before exporting: no request carries the document. It is read, changed and saved in your browser.
