What Does Adding Page Numbers Do?
Adding page numbers stamps a small text label on the bottom of every page in your PDF (Portable Document Format) file. Numbered pages make long documents easier to reference, navigate, and cite, and they help readers keep printed pages in order. According to MDN Web Docs, a PDF is a fixed-layout document format, so text drawn onto a page becomes part of that page exactly where you place it.
This tool uses pdf-lib, a JavaScript library, to draw the numbers directly onto your pages in your browser. You control the position (bottom center, bottom right, or bottom left) and the format (plain running numbers, or a "Page 1 of N" style that also shows the total page count). Because the work happens locally, your file is never uploaded to a server and stays private.
The operation is lightweight and lossless. The original text, images, and layout of your PDF are left untouched; only a small number is added near the bottom margin of each page.
How It Works
The tool uses pdf-lib to draw page numbers directly onto your PDF in the browser. Here is the process:
Upload PDF File
Select your PDF file. The tool loads it in your browser and shows the total number of pages so you know what will be numbered.
Choose Position and Format
Pick where the numbers sit (bottom center, right, or left) and choose the format: plain numbers or "Page 1 of N".
Add and Download
Click Add Page Numbers to stamp every page. When it finishes, download your numbered PDF, saved as numbered-yourfile.pdf.
Frequently Asked Questions
How do I add page numbers to a PDF?
Upload your PDF file using the upload button. Choose where the page numbers should appear (bottom center, bottom right, or bottom left) and pick a format (plain numbers like 1, 2, 3 or "Page 1 of N"). Click Add Page Numbers, then download your numbered PDF. Everything runs in your browser.
Is this page numbering tool free?
Yes, adding page numbers is 100% free. There is no registration, no account, and no hidden fees. The tool works entirely in your browser, so your files stay on your device and remain private.
Where do the page numbers appear on the page?
You choose the position. The tool places numbers along the bottom of each page and lets you align them to the bottom center, bottom right, or bottom left. Numbers are stamped near the bottom margin so they stay clear of most body text.
Do my files get uploaded to a server?
No. All processing happens locally in your browser using client-side JavaScript. Your PDF never leaves your device and is never sent to or stored on any server, which keeps sensitive documents private.
What page number formats can I choose?
Two formats are available. The plain format stamps a simple running number on each page (1, 2, 3 and so on). The "Page 1 of N" format shows both the current page and the total page count, which is useful for printed reports and handouts.
Does adding page numbers reduce PDF quality?
No. The tool only draws a small text label on top of each existing page. It does not re-render, compress, or rasterize your pages, so all original text, images, and formatting stay at their original quality.
