Frequently Asked Questions

The tool uses pdf-lib.js to open your PDF entirely in your browser, draw page numbers on each page at your chosen position, and save the result. No files are uploaded to any server — everything happens client-side on your device.

Yes. You can choose the position (top or bottom, left, center, or right), set a starting number, adjust font size, and select the number format. This lets you match your document's formatting requirements precisely.

Yes. The entire process runs 100% in your browser. Your PDF is never uploaded to any server. You can verify this by checking your browser's Network tab during processing — no file data is sent anywhere.

Yes. You can set a custom start page so the tool skips numbering on initial pages such as the title page or table of contents. You can also set the starting number to match your document's pagination needs.

The increase is negligible. Page numbers are added as lightweight text elements, typically adding only a few kilobytes to the overall file size regardless of the number of pages.

Adding page numbers without breaking your document

Page numbers are essential for documents that will be printed, bound, or formally submitted: thesis chapters, court filings, regulatory submissions, school reports, project proposals. The challenge is adding them after the fact, on a PDF you do not have the source for — perhaps a scanned document, a finished export, or a third-party file. This tool draws fresh page numbers in the position you choose without disturbing existing content.

Where to place page numbers

Bottom centre is the most neutral and works for almost any document type.
Bottom outside corner (alternating left/right on facing pages) is standard for bound print and academic theses.
Top right is common for legal filings, where rules sometimes require numbers in a specific corner.

Numbering schemes

The simplest scheme is "Page X" or "X of Y". For longer documents, the "X of Y" pattern is friendlier because readers know how much remains. For documents with front matter, you may want roman numerals on early pages (i, ii, iii) and arabic numerals from the body (1, 2, 3). Set the start number accordingly when you add the body pages.

What to watch for

Adding numbers in the bottom margin can collide with existing footers. Inspect a sample page before processing the full document; nudge the position if needed. If the original PDF already has page numbers, consider whether you really want a second set. For court filings, follow the jurisdiction's exact placement and font rules — these vary widely.
