Add page numbers to PDF: free online tool & guide
Page numbers turn raw PDFs into professional documents. Whether it's a report, manual, or thesis, our tool lets you add custom page numbers without uploading files – everything stays in your browser. Choose from several formats: simple digits, "Page X", "X of Y", or fractions. Fine‑tune with font, colour, opacity, and exact position.
Why use our PDF numbering tool?
- 100% free – no watermarks, no sign‑up.
- Batch process – add numbers to 10 PDFs at once, download individually or as ZIP.
- Custom range – skip cover pages, number only sections.
- Privacy first – files never leave your device (client‑side PDF‑lib).
- Presets – save your favourite style (stored locally).
How it works (quick steps)
- Upload one or multiple PDFs (drag & drop or click).
- Adjust numbering style: format, font, size, colour, opacity.
- Pick a corner or set custom X/Y coordinates.
- Choose all pages or a custom range (e.g. 2-6,8).
- Preview the result on the first page.
- Click “Add page numbers” and download your files.
Comparing with other tools
Unlike Adobe Acrobat or Smallpdf, our tool is completely free, has no file size limit (except reasonable 25MB per file for performance), and doesn't send your documents to any server. You get more format options than most free online pagination tools, plus real‑time preview.
