QuickMergeInsert Page Numbers in a PDF
Short answer: To add page numbers to a PDF, choose the position, starting number and style, then download the numbered copy. QuickMerge adds the numbers in your browser without uploading the document.
Insert page numbers into a PDF and choose where they sit, what number they start from and how they read — a plain numeral, "Page 4", or "4 of 12". The numbers are drawn into the document in your browser, so the file is never uploaded.

Number Your PDF Pages in Seconds
Add clean, consistent page numbers to any PDF — essential for reports, contracts, manuscripts, and legal filings where every page needs a reference. Choose where the numbers sit, what number to start from, and whether they read as a plain 1, Page 1, or 1 of N.
Numbers are drawn as real text onto each page with pdf-lib. Everything runs on your device via open-source browser libraries — your file is never uploaded. You can verify it yourself.
Next steps
Before this step
- settle the page order first — numbering added before reordering will be wrong.
- combine the documents first — so numbering runs continuously across the whole set.
What to do with the result
- add a DRAFT or CONFIDENTIAL mark — if the numbered document is for review.

Frequently Asked Questions
Any of six positions: bottom or top, left / centre / right. Bottom centre is the most common default.
Yes — set any starting value (useful when a document continues from an earlier part, or when a cover page should not count).
Plain numbers (1, 2, 3), Page 1 style, or 1 of N which also shows the total page count.
No. The numbers are added locally with pdf-lib and your document never leaves your device.
Set the starting number so the count begins where you want it. This is the standard fix for documents with a cover or a table of contents that should not be counted.
Yes. The format is selectable between a plain numeral, "Page 1", and "1 of N", where N is filled in from the document length automatically.
Yes — numbers are drawn onto the page and do not require a text layer. If you also need the scan to be searchable, run OCR on it first.
They are placed in the margin at the position you choose. On documents with very tight margins or existing footers, check the preview and move the position if there is a collision.
Merge the files first, then number the combined document. Numbering each file separately and merging afterwards restarts the count at every join.
Load the document, choose a position, a starting number and a format, then download. The numbers are drawn onto each page, so it works on scans and image-only PDFs as well as text ones. Do it after any reordering — numbers are fixed once written and will not follow a page that moves.
Yes — set the starting number so the count begins where you want it. This is the standard fix for a document with a cover or a contents page that should not be counted.
That is a Word feature: Insert → Page Number, then pick a position, and use Format Page Numbers to change where the count starts. Word numbers live, so they update as you edit — which is why it is worth doing there if the document is still being written, and here if it has already been exported to PDF.
Merge the files first, then number the combined document. Numbering each file separately and merging afterwards restarts the count at every join.
Number the document readers will actually receive
Page labels often go wrong when a cover sheet, table of contents or scanned insert is added after numbering. Organize the final PDF pages first, then apply numbers once.
Choose the right starting point
If a cover should remain unnumbered, exclude it or start the visible sequence on the following page. Legal and tender documents may require every physical sheet to be numbered, including blank pages. Match the submission rule rather than assuming page one is always the first visible numeral.
Protect the safe area
Footers can collide with existing text, signatures, crop marks or printer margins. Preview several page types—not only the first page—and leave comfortable space from the edge. A centred footer is predictable; outside-corner numbering can be easier to scan in long reports.
Verify the exported PDF
Open the download and inspect the first, middle and final pages. Confirm sequence, placement and contrast, then search for any old page numbers already baked into scans. QuickMerge adds visible numbers but does not remove numbering that is part of the original page artwork.

Numbering is easy to apply and easy to get subtly wrong
The mechanics take seconds. These are the details that cause a numbered document to come back for a second pass.
Fix the page order before numbering, not after
Numbers are stamped against the current sequence. Reorder the document afterwards and the numbers no longer match. Settle the order in the organize tool — including deletions and rotations — and number last.
Cover pages usually should not count
A cover or title page that carries a "1" is the most common reason a numbered PDF looks wrong. Set the starting number so the first numbered page is the one a reader would call page one; the starting value is adjustable for exactly this.
Match the position to the binding
Numbers in an outer corner disappear into the gutter on double-sided printing and can be trimmed off entirely by a print shop. Centre-bottom is the safest position for anything that will be physically bound.
How to put page numbers in a PDF after the fact
Numbering a PDF is different from numbering in a word processor, because the document is finished — there is no header region to type into and no field that recalculates.
The numbers are drawn onto the page, not inserted into a header
A PDF has no live header or footer. Adding page numbers means stamping text at a position on each page, which is why it works on any PDF at all — including a scan, which has no text to flow around. It also means the numbers are fixed once written: if the page order changes afterwards, they do not follow.
Settle the page order before numbering, never after
This is the single most common thing to get wrong. Numbers are stamped against the sequence in front of them, so reordering, deleting or inserting a page afterwards leaves a document whose numbering no longer matches. Do the structural work in the organize tool first, or merge the files if the document is being assembled from several — then number last, once.
A cover page usually should not be page one
A title page or a table of contents carrying a "1" is the giveaway of an automatically numbered document. The starting number is adjustable for exactly this: set it so the first numbered page is the one a reader would call page one, and the front matter stays unnumbered.
Position matters more on anything being printed
Numbers in an outer corner vanish into the gutter on double-sided printing, and a print shop trimming to size can cut them off entirely. Centre-bottom is the safest position for anything physically bound. Check the preview on documents with tight margins or an existing footer, and move the position if the two collide.
