Add Page Numbers

Merged reports have a way of reaching the printer as one anonymous stack of white pages. This tool lets you add page numbers to pdf documents in the browser before that happens: upload the file, pick one of six corner or center positions, set the font size and the number to start counting from, and watch every thumbnail update live with the stamp in place. When it looks right, one click bakes real Helvetica numerals into the file and downloads the numbered copy. It's the kind of pdf page number tool you want right after combining chapters from different authors, because the moment a printed stack hits the floor, unnumbered pages become a sorting puzzle nobody enjoys.

How to use

01

Upload the report

Drag in your PDF, up to 100 MB. The controls column appears on the left with the filename, and thumbnails of every page render on the right.

02

Choose position, size, and start

Pick from six placement buttons: bottom or top, then left, center, or right. Set a font size between 6 and 36 points, and change Start at if counting shouldn't begin at 1.

03

Apply & download

Every thumbnail previews the number in your chosen corner as you adjust. Press Apply & download, and the numerals are drawn into the file, saved with a -numbered suffix.

Why Add Page Numbers

Common questions

Which positions can the page number stamp use?
Six: bottom center, bottom right, bottom left, top center, top right, and top left. The stamp sits 30 points in from the page edge in Helvetica, colored dark grey so it reads clearly without shouting.
Can page numbering start at something other than 1?
Yes, the Start at field accepts any positive number. That's useful when a cover and table of contents live in a separate file, or when an appendix should continue counting from the main report.
How do I insert page numbers pdf online without hitting existing footers?
Switch to one of the three top positions, or study the live thumbnails before committing. The preview mirrors the chosen corner and relative size, so a collision is visible before you download anything.
Does the numbering preview show exactly what gets printed?
The thumbnails use a scaled overlay, so treat them as placement guides rather than pixel proofs. The downloaded file contains the real stamp, Helvetica at your chosen point size, drawn by pdf-lib at 30 points from the edges.
What format do the page numbers take?
Plain numerals only: 1, 2, 3, or whatever your starting value implies. There's no Page X of Y mode and no roman numerals, which keeps the stamp compact. For roman-numbered front matter, handle that section separately before merging.
Will page numbering work on a PDF with mixed page sizes?
Yes. The position is computed from each page's own dimensions, so a landscape A3 chart in the middle of an A4 report still gets its number in the same relative corner.
Is the file uploaded while pages are being numbered?
No, the whole run happens client-side. Your document loads into browser memory, gets stamped by pdf-lib, and downloads from your own machine, which matters when the report contains unreleased financials.
How do I insert page number in pdf files with this tool?
Pick one of six positions, set a font size between 6 and 36 points, and press Apply & download. The pdf page number add step draws real Helvetica numerals into the file, not a temporary overlay, and the copy saves with a -numbered suffix.
Can I add page numbers to pdf online without installing software?
Yes, the whole run happens in your browser. You add page numbers to pdf online by uploading the file, choosing a corner, and downloading the stamped copy, with nothing sent to a server. To insert page number in pdf online this way you only need a modern browser.
Is it free to add page numbers to pdf free of charge and watermarks?
Yes. There's no account, no fee, and no branding stamped onto your file, so you can add page numbers to pdf free whenever you need. The option to insert page numbers in pdf free works the same on every file up to 100 MB.
How do I put page number in pdf documents in a specific corner?
Use the six position buttons: bottom or top, then left, center, or right. When you put page number in pdf files this way, the live thumbnails show the placement before you commit. You can give page number to pdf pages in whichever corner clears any existing footer.
What's the difference between add page no in pdf and insert page no in pdf here?
Nothing, they're the same action described two ways. Whether you call it add page no in pdf or insert page no in pdf, the tool stamps plain numerals in your chosen spot. There's no Page X of Y mode and no roman numerals, which keeps each stamp compact.
Does this pdf numbering online tool bake the numbers in permanently?
Yes. This pdf numbering online tool draws the numerals into the page content with pdf-lib, so they print and export like any other text. Because the online page numbering in pdf happens in Helvetica at your chosen size, the result reads cleanly at any zoom.
Can I change page numbers in pdf pages that were stamped before?
You can restamp with a different Start at value, but the tool can't rewrite numerals already baked into a page. So to change page numbers in pdf files that already carry them, you'd first replace the old page or use a full editor. This tool adds a new set of numbers rather than editing an existing set.
Can I edit page numbers in pdf content that came with the file?
Not directly. To edit page numbers in pdf files, meaning numerals already drawn into the original, you need an editor that rewrites page content, since this tool only stamps a fresh sequence. The Start at field lets you match a new sequence to an existing one, which covers most real cases.
Can this tool add pages to pdf, not just page numbers?
No, this page stamps numbers rather than inserting content. To add pages to pdf documents, use Merge PDF to bring another file in or Organize PDF to duplicate an existing page. A pdf file page add job belongs to those tools, not to page numbering.
How do I insert page in pdf online as new content here?
You can't insert content on this page; it only numbers existing pages. To insert page in pdf online with real content, merge in another PDF with Merge PDF, or duplicate a page in Organize PDF. Both let you insert page in pdf online free the same way this numbering tool is free.
Is there an online pdf page add feature on this page?
Not for adding whole pages, no. An online pdf page add task, where you slot a new sheet into a document, is what Merge PDF and Organize PDF handle. This tool is dedicated to numbering, so a page add in pdf online workflow starts with one of those instead.
Can I add pages to pdf free on this numbering page?
Adding pages isn't what this tool does, but you can still do it at no cost elsewhere on the site. Use Merge PDF to add pages to pdf free, and it runs in your browser just like this one. There's an add pages to pdf free online route through Organize PDF too, for duplicating pages you already have.
