Add page numbers stamps a simple 'page / total' label at the bottom of every page — left, center, or right.
How to use
- Upload the PDF.
- Pick a position: bottom-left, bottom-center, or bottom-right.
- Download the PDF with numbering applied.
Use cases
- Prepare a PDF for printing or handing off with identifiable pages.
- Add numbering to a merged PDF that lost its original order.
Limits
- Simple numbering with embedded Helvetica.
- No font, color, custom prefix, or partial-range options in this version.
- Doesn't promise to preserve digital signatures, interactive forms, or complex annotations: pdf-lib re-serializes the document.
Privacy
The file is processed in your browser — we don't upload it to Modulaq.
Common errors
- An encrypted or damaged PDF may not be processable.
- If the PDF has digital signatures, they may be invalidated on re-save.
Technical notes
- Uses pdf-lib with StandardFonts.Helvetica and drawText at the bottom of each page.
