Add Page Numbers to PDF
Number every page of a PDF — choose the corner, the starting number and whether it reads “1” or “Page 1 of 12”. Done in your browser, with nothing uploaded.
Your PDF is numbered in your browser — nothing is uploaded.

How it works
When you select a PDF, the tool loads it in your browser with the open-source pdf-lib library and counts the pages. It then draws a small number onto each page at the position you chose, increasing by one as it goes. If you pick the “Page N of M” format, the M is filled in from the total page count so every page agrees on the total. The result is saved as a new PDF. All of the work happens on your device, so your document is never uploaded to a server, and the original file is left untouched.

Picking a numbering style
For most documents a plain number in the bottom centre or bottom right is the safe default — it is where readers expect to find it and it rarely clashes with body text. The “Page N of M” format earns its keep on anything that gets printed and handed around: a reader who drops a stack of paper can see at a glance whether a page is missing. The start at control matters more than it first appears. A report often opens with a cover and a contents page that should not count as page one, so you would start the numbering a page or two in; a document that continues a series might start at 13 so it picks up where the previous file left off.
Why number pages in your browser
Adding page numbers sounds harmless, but the documents that need them — contracts, reports, submissions, manuscripts — are often the ones you would least like to upload to an unknown server. A typical online tool sends your file away, stamps it, and sends it back, so the document leaves your control for the round trip. This tool does the whole job locally: the PDF is read, numbered and saved on your own device, with no upload, no account, and no watermark added to the output. After the first visit the page is cached, so it keeps working with no internet, and there is no cap on how many pages or how many files you can number.

Frequently asked questions
Can I start numbering from a number other than 1?
Yes. Set the starting number to anything you like. This is handy when the front matter is unnumbered, or when a chapter continues the page count from an earlier file.
Can I show “Page 1 of 10” instead of just “1”?
Yes. Choose the format: a plain number, “Page N”, or “Page N of M” where M is the total page count. The total is worked out automatically from your document.
Where do the numbers go?
You choose. Pick any of six positions — the bottom or top of the page, on the left, centre or right — to match your document’s layout.
Are my files uploaded to a server?
No. The numbers are drawn into the PDF entirely in your browser with the open-source pdf-lib library. Your file is never uploaded, stored, or sent anywhere.
Will the numbers overlap my existing content?
They sit in the margin at the position you choose, so on most documents they clear the body text. If a page has a full-bleed footer, move the numbers to the opposite corner or the top.
Does numbering reduce the quality of the PDF?
No. Only the small number text is added; the existing pages, fonts and images are untouched, so there is no loss of quality and the file size barely changes.
