Number every page, with your choice of position and style. 100% free, no sign-up — your file never leaves this browser tab.
Add Page Numbers lets you add page numbers to a PDF entirely inside your browser, with no software to install and no account to create. Like every tool on Techsinghge Smart Tools, it's built around adding a finishing touch to a document — text, numbers, images, or metadata, and it works the same way whether you're on a laptop, a Chromebook, or a phone.
Under the hood, Add Page Numbers takes one PDF file and hands back a PDF with page numbers added to every page. Your file is loaded directly into this page's memory using JavaScript — nothing is transmitted to a server, which means there's no upload wait, no file-size cap tied to a paid plan, and no copy of your document left sitting on someone else's storage once you're done.
Numbering pages of a report before printing and binding is one of the most common reasons people reach for this tool, but it works just as well for adding page numbers to a scanned document for easier reference. If you need a related step before or after this one, check the related tools further down the page — every tool on this site is designed to slot into the same drag-and-drop workflow.
No installs, no accounts — just your browser doing the work.
Scroll up (or tap “Use Add Page Numbers now”) to load the tool instantly — no account or install needed.
Drag and drop one PDF file into the drop zone below, or click it to browse your device.
Adjust whatever settings this tool offers so the result comes out exactly how you want it — sensible defaults are already selected.
Click Run, then download a PDF with page numbers added to every page straight to your device — it's generated locally and ready in seconds.
Place numbers in any corner or centered, top or bottom, in the format you prefer.
Begin numbering from page 1 or any custom starting number you choose.
Your one PDF file stays on this device the whole time — nothing is uploaded, logged, or stored on a server.
Processing happens right in this browser tab, so there's no upload progress bar, no server queue, and no processing fee.
Because Add Page Numbers runs locally, teams handling sensitive paperwork — legal, HR, healthcare admin, finance — can use it without the compliance questions that come with uploading documents to a third-party server. And if you only need it for a single one-off task, it's just as useful with zero setup and nothing to remember to delete afterwards.

Numbers are placed in the margin area by default to avoid overlapping the page's existing content.
