A QUICK WALKTHROUGH
How to use this tool
- Choose one PDF up to 50 MiB and 500 pages.
- Set start (1–1,000,000), font size (6–36 pt), skipped opening pages and one of six positions.
- Choose N, N / last number, or the English literal Page N; review and download.
Numbering semantics
Skip an integer number of opening pages from 0 to pageCount − 1. The first remaining page receives start, then each numbered page increments by one. Start is an integer from 1 to 1,000,000; the last assigned number may exceed that start limit. The N / last number denominator is start + numberedPages − 1. Page N always uses the English ASCII word Page in every interface language.
Text and placement
Uses existing pdf-lib 1.17.1 and standard Helvetica, finite font size 6–36 pt and fixed 24 pt margins. Six header/footer positions use the visible CropBox/MediaBox intersection and 0/90/180/270-degree page rotation. Non-unit UserUnit, invalid geometry or insufficient label width/height is rejected. No Unicode font embedding. Existing page content is not rasterized; PDF text is overlaid, which can cover existing content.
Local rewrite limits
One PDF, 50 MiB and 1–500 pages. Password-protected, encrypted, signed, XFA, damaged and unsupported PDFs are rejected. Rewriting may remove unsupported advanced features and changes PDF bytes; retain your original. Local processing, no upload or storage. Cancel or changing input invalidates unfinished results.
GOOD TO KNOW
Common questions
What does the denominator mean?
It is the final assigned number, not the physical number of pages. For start 10 and three numbered pages, it is 12.
Is the original file changed?
No. Download a newly written copy. Review its layout and features before using it.
