Doruni writes the numbers onto the chosen pages and creates a new PDF.
Skip a cover. Number only the pages readers need.
The PDF page range and displayed number are separate controls. That makes common academic and business numbering patterns possible without manual editing.
- Six familiar header and footer positions with a live preview.
- Four number formats plus size, colour and margin controls.
- Choose the first and last numbered PDF page and its starting number.
Enough control for a clean document.
The numbers are added as new PDF text. Doruni does not replace existing printed numbers or change PDF page labels.
PositionsTop or bottom, aligned left, centre or right.
SequenceStart on any page and choose the first displayed number.
FormatsNumber only, “Page 1”, or current page over total.
Important limitExisting headers, footers and printed page numbers are not detected automatically.
Plan the sequence before adding it.
Can I leave the cover page unnumbered?
Yes. Set “Start on page” to 2, then choose the number that should appear on that page.
Can the first visible number be different from the PDF page?
Yes. The start page and start number are independent.
Does Doruni remove existing page numbers?
No. Existing numbers are page content. Check the previews and choose a position that does not overlap them.
Does numbering work with signed PDFs?
Adding content modifies the PDF and invalidates an existing digital signature. Number the final document before signing it.
