How to add page numbers to a PDF in 3 steps
The whole process runs in your browser — there's no software to install and nothing to upload.
1. Select your PDF
Click "Select PDF File" or drag and drop the document you want numbered into the tool.
2. Set your numbering
Pick the position, starting number, and format — then choose which pages get numbered.
3. Download your numbered PDF
Apply the numbering and download the result. Nothing is sent to a server at any point.
Why people add page numbers to PDFs
Page numbers make a long document usable. Without them, referencing "the third page" or finding your place after printing means counting sheets by hand. With them, a reader can jump straight to where they need to be — and so can you.
Common examples: numbering a report or thesis before submission, adding page numbers to a contract so clauses can be cited precisely, preparing a printed handout or workbook, or finishing off an e-book or manual that was assembled from several source files.
Most original documents — especially ones exported from a word processor or merged from scans — don't have page numbers baked in. Adding them after the fact, in one pass, is the quickest fix.
What to expect
Position and format are yours to set
Place numbers in the bottom center, bottom corner, or top of the page — whichever matches the layout you're working with. Choose a plain number, "Page X", or "X of Y" if you want the total page count included.
Start from any number
If your PDF is a chapter or section that continues from a previous document, set a custom starting number instead of beginning at 1.
Applies to every page
Numbering is added across the whole document in a single pass — there's no need to repeat the process page by page.
No file size limits
There's no cap on how large your PDF can be. The practical limit is your device's available memory.
Your files stay on your device
Most online PDF numbering tools upload your document to a remote server, stamp it there, and return the result. That means your file — and whatever's in it — passes through someone else's infrastructure.
itsmypdf works differently. Page numbers are added entirely in your browser using JavaScript. Your file is read locally, stamped locally, and the output is saved locally. The tool does not upload your file to a server. You could turn off your internet connection after the page loads and the tool would still work.
This matters if you're numbering anything sensitive: contracts, financial statements, legal documents, or internal drafts. The browser-based model isn't a marketing claim — it's the technical architecture.
