How to Add Page Numbers to a PDF Online
Page numbers make long PDFs easier to cite and review. With a browser tool, you can place a simple number or a “Page 1 of 20” style label without uploading the document contents to HatchMyPDF.
In short: Upload the PDF, choose where and how numbers should appear, preview representative pages, and download the numbered copy.
Choose numbering that fits the page
Position and margins matter because PDFs can use different page sizes and orientations. A small offset may be enough for a report with generous margins, while scanned pages may need a different corner or larger inset. Use a consistent format and readable size.
Step-by-step
- Add the PDF — Open the numbering tool and select the document from your device.
- Configure the numbering — Choose the position, format, starting value, margins, font size, and other available options.
- Preview and save — Check pages with different layouts, generate the result, and download the numbered PDF.
What to check before downloading
A number can overlap existing headers, footers, crop marks, or scanned content. Review portrait and landscape pages separately before using the result as a final record.

Common questions
Can numbering start above 1?
Yes. Use the starting-number control when the PDF continues an earlier document or front matter uses another scheme.
Does this change the original file?
The tool creates a new downloadable PDF. Keep the original until you have reviewed the numbering.
