How it works
A clean sequence, exactly where it belongs.
Choose the pages first, shape the numbering second, and download only after the structural verification pass succeeds.
- 01
Open one PDF
Choose a PDF up to 75 MB and 500 pages. Toolkit validates its structure and renders the document locally for preview.
- 02
Design the numbering
Select all, odd, even, or custom pages; set the first number; then choose the format, position, font, size, color, opacity, and margins.
- 03
Verify and download
Toolkit adds real vector text, reopens the output to verify every page's count, dimensions, and rotation, then starts the download.
Designed for real documents
Flexible numbering without flattening the PDF.
Precise, readable typography
Use four dependable built-in PDF fonts, six header or footer positions, four numbering formats, custom margins, color, size, and opacity.
Private structural output
The original page content is not rasterized or recompressed. Processing and verification stay in browser memory, with no upload or backend PDF worker.
PDF page-number questions
Ranges, formats, privacy, quality, and document features.
How do I add page numbers to only part of a PDF?+
Enter a page range such as 2-8, 11, 14-20, then choose Apply. The starting number is assigned to the first selected page and increases through the selected sequence.
Can I skip the cover and begin with page 1?+
Yes. If the cover is source page 1, select pages 2 through the end and leave First number set to 1.
What page-number formats are available?+
Choose a plain number, Page 1, 1 / 12, or Page 1 of 12. For total formats, the total is the ending number in the selected numbering sequence.
Will adding numbers reduce PDF quality?+
No. Toolkit adds vector text over each selected page. Existing selectable text, vector art, and images are not converted into screenshots or recompressed.
Are my files uploaded?+
No. PDF.js renders the preview locally and pdf-lib writes and verifies the page numbers in browser memory. Closing or refreshing the tab clears the workspace.
Can I number an encrypted PDF?+
Not in this version. Password-protected and encrypted PDFs are rejected. Unlock an authorized copy in software you trust before using the tool.
What happens to forms, bookmarks, and signatures?+
The tool edits the original document instead of copying pages into a new one, which gives advanced features a better chance of remaining intact. However, rewriting a complex PDF can still affect some features, and every existing digital signature becomes invalid.
