Number every page in one step
Page numbers seem like a small thing until you have a long PDF without them — a report, a manuscript, a contract, a set of notes — and you need to reference a particular page or keep a printed stack in order. Adding them by hand is not really possible in most PDF viewers, and recreating the document just to get numbering is overkill. This tool stamps page numbers onto every page of your PDF in a single step. You drop in the file and it adds clean, consistent numbers across the whole document, so each page is clearly marked. This makes a long PDF far easier to navigate, cite and print: you can tell someone to 'see page 14', keep a printout collated, and give the document the finished, professional feel that numbered pages provide. Instead of wrestling with software or leaving a document unnumbered, you get properly paginated output in moments, ready to share or print.
Put the numbers where you want them
Where a page number sits is a matter of both convention and preference, so this tool lets you choose the position rather than forcing one on you. You can place the numbers at the bottom center, the most common spot for reports and books; at the bottom right or bottom left, which suit certain document styles and binding choices; or at the top of the page if that fits your layout better. The numbers are added with sensible margins so they sit neatly near the edge without crowding the content or running off the page. Being able to pick the position means the numbering matches the kind of document you are working with — a formal report, a bound manuscript, a printed handout — and looks intentional rather than awkwardly placed. It is the difference between page numbers that feel like part of the document's design and ones that look bolted on, and it takes nothing more than choosing the spot that fits.
Control the starting number and format
Real documents do not always start their numbering at one on the first physical page, so this tool gives you control over where the count begins and how it reads. You can set the starting number, which is essential when your PDF is a section of a larger document, when the first pages are a cover or table of contents that should not count, or when you are continuing the numbering from another file. You can also choose to show the total, turning a plain '7' into a more informative '7 of 20', which helps readers see at a glance how much of the document remains and is reassuring on printouts that nothing is missing. These options mean the numbering reflects how your document is actually structured rather than a rigid default. Whether you need a simple count from one, a sequence that starts partway through, or the fuller 'page X of N' style, you can set it up to match exactly what the document calls for.
Private by design — stamped in your browser
The PDFs people number are often documents they care about and would rather keep private: reports, contracts, drafts, financial or legal paperwork. Uploading such a file to a server just to add page numbers would mean handing the whole document to a third party for a trivial change. In1 adds the page numbers entirely in your browser, modifying the PDF on your own device. Nothing is uploaded, nothing is stored, and there is no account or sign-up. Because there is no upload step, the process is fast and works exactly the same offline as online. This local-only approach matters because the documents being numbered are frequently confidential, and there is no reason to expose them to an online service for something as simple as pagination. You get the convenience of an instant tool with the assurance that your PDF never leaves your computer. Number as many PDFs as you like, free and without watermarks, with every file processed privately on your own machine.
Who adds page numbers to PDFs?
The need spans professional and personal document work. People preparing reports, proposals and whitepapers add page numbers so the documents look finished and are easy to reference and discuss. Writers and authors number the pages of manuscripts and drafts before sharing them with editors or readers. Students paginate essays, dissertations and assignments to meet submission requirements. Legal and administrative staff add numbers to contracts, filings and records where page references matter. People assembling printed handouts, booklets or bound documents number the pages so a printed stack stays in order. Anyone who has received or created a long PDF without page numbers and found it awkward to navigate or cite has a use for this tool. Because it lets you choose the position, the starting number and the format, and does it instantly and privately in the browser, it handles everything from a quick count on a casual document to the precise pagination a formal report or legal file requires.
