Why people add page numbers

Page numbers turn a PDF from a bag of pages into a navigable document. They’re mandatory for legal exhibits, expected for academic submissions, and just plain useful when someone needs to reference ‘page 47.’

Legal exhibits

Court filings often require pagination on every supporting exhibit. Stamp Bates-style numbers on a binder of evidence in seconds.

Academic submissions

Theses, journal manuscripts, and conference papers expect page numbers. Add ‘Page 1 of N’ before submission.

Multi-section reports

When you concatenate sections from different sources, the original page numbers get out of sync. Re-number end-to-end so the table of contents matches.

Reference packages

Sales decks and proposals reviewed in meetings need pagination so attendees can call out ‘back to page 12.’

Print-prep

Print shops process paginated docs faster — saves a back-and-forth when re-prints are needed for specific pages.

Scan archives

After scanning a stack of paper, page numbers help future-you find the page you need without flipping through the whole archive.

How Add Page Numbers works

Three steps, no signup, no uploads.

STEP 1
Drop your PDF
Up to 100 MB. Files stay in your browser — pdf-lib reads and writes locally.
STEP 2
Pick position + format
Six positions (corners + bottom/top center). Four formats: bare number, ‘1 of N’, ‘Page 1’, ‘Page 1 of N.’ Font size from 6–48 pt.
STEP 3
Apply & download
We embed Helvetica and stamp each page via drawText. Lossless overlay — the underlying content stream is untouched.

What makes pdfcraft ai different

Same engine Chrome uses
PDFium is Google's PDF engine — the one that powers Chrome's built-in PDF viewer. We compile it to WebAssembly so it runs in your browser at near-native speed.
100% local processing
Most free PDF tools upload your file to a server, process it, and stream the result back. We don't. Your file lives in your browser tab and never touches our infrastructure. Verifiable in your browser's Network panel.
No watermark, no signup, no daily limit
Convert 1 PDF or 1,000. We don't gate on volume because there's nothing to gate on — the engine runs on your machine.
Honest about limitations
When something the tool can't do (encrypted PDFs, cross-reference streams), we tell you clearly instead of failing silently. Same for partial results: sampled vs exact, embedded vs not.
Open standards, free engines
PDFium is BSD/Apache licensed (free for any use). We don't pay vendor license fees and pass that savings on to you (and to ourselves) as a free, ad-supported tool with no upgrade-to-pro pressure.

Frequently asked questions

Is anything uploaded?

No. pdf-lib runs in your browser. The PDF never touches our servers.

Will the numbers overlap with existing content?

Possibly — we draw on top of whatever’s on the page. If the page already has a footer at the position you choose, the new number will overlap. Pick a different position, or strip existing footers first.

Can I number only certain pages?

The current version numbers every page. A startPage option exists in the op but isn’t exposed in the UI yet — for now, use Extract Pages first to isolate the pages, number them, and merge back.

What about Roman numerals or section-specific numbering?

Not in v1. Most users want simple Arabic numerals. Section-aware numbering (‘i, ii, iii’ for front matter then ‘1, 2, 3’ for the body) is on the roadmap.

Does the font support non-Latin scripts?

Helvetica covers Latin + Western European characters. CJK scripts (Chinese, Japanese, Korean) need different fonts; not supported in v1.

Need to rotate or reorder pages first?

Rotate fixes upside-down pages before numbering. Sort Pages reorders before numbers go on.
