Page Numbers
Add page numbers to any PDF — choose position, format, and starting number.
PDFs assembled from scanned pages, merged from multiple sources, or exported from design tools often arrive without page numbers. Adding them by hand in a desktop app takes more steps than it should. This tool lets you drop in any PDF and stamp clean, correctly formatted numbers on every page in seconds. You control where they appear (six edge positions), how they read (plain number, "Page N", "N of total"), what size they are, and what number to start from — useful when this document is part of a larger series and needs to continue from a previous section. Processing runs entirely via pdf-lib in your browser.
How to Use
- 1
Drop your PDF onto the upload area, or click to browse.

- 3
Select a position (bottom-center is the most common), and adjust the font size.
- 4
Set the starting number if the document is a continuation of a larger series.
- 5
Click "Add Page Numbers" and download the result.
Frequently Asked Questions
Can I start numbering from something other than 1?
Yes. Set any starting number in the "Start at" field — handy when this PDF is a chapter that should continue the page count from a previous document.
What format options are there?
Four: plain numbers (1, 2, 3…), "Page N" (Page 1, Page 2…), "N of Total" (1 of 24, 2 of 24…), and "Page N of Total" (Page 1 of 24…). The total is calculated automatically from your PDF.
Where can the numbers be placed?
Bottom-center, bottom-right, bottom-left, top-center, top-right, or top-left. Numbers are inset from the edge with a margin so they sit within the printable area.
Could the numbers overlap existing content?
They are placed near the page margins. If your PDF has content right at the edge, a smaller font size or different position will avoid overlap.
