Add Page Numbers to PDF — In Your Browser
Add page numbers to a PDF in your browser—nothing is uploaded to a server. Steps: open a PDF, choose bottom-center or a corner, set the first number (default 1), margin, and font size, optionally use “Page N” format, add numbers, then download. Example: a three-page sample loads with bottom-center numbers starting at 1 and enables Download for numbered.pdf. Encrypted files fail with a clear error.
How it works
Choose one PDF, pick a position (bottom-center by default), set the first page number, margin, and font size, click Add numbers, then Download. Numbers are drawn on every page with drawText. Libraries load on first use.
Rules you should expect
Numbering positions, start value, format, privacy, and failure cases for local PDF page numbers.
- Position: bottom-center (default), bottom/top center, or any corner. Margin is in PDF points (default 24 pt).
- Start at: first visible number on page 1 of the file (default 1). Each next page adds 1—useful after deleting pages in Organize PDF.
- Format: plain digit or “Page N”. Font size default 12 pt. Output is a new PDF; original bytes are not sent to a server.
- Limits: encrypted or corrupt PDFs fail clearly; files over ~25 MB may be slow; numbers are burned in—removal needs the original.
Example
Sample builds a three-page PDF, adds bottom-center numbers starting at 1 on every page, and enables Download for numbered.pdf.
Good fits
- Office: number a report before printing so colleagues can cite “page 12”.
- Students: add 1–N footer numbers to a thesis export after merging chapters.
- Site owners: stamp page numbers on handouts downloaded from Organize PDF or watermark drafts.
Frequently asked questions
Is my PDF uploaded?
No. The PDF library runs in your tab (scripts may load from a CDN). Your PDF is not uploaded to our servers.
Can I start numbering after a cover page?
Yes—set “Start at” to the number you want on page 1 (e.g. 0 for a cover that should not count, or 5 if earlier pages were removed elsewhere). Every following page increments by 1.
What formats and positions are supported?
Pick plain numbers (1, 2, 3…) or “Page N” labels. Position, margin (pt), and font size apply to every page the same way.
What about encrypted PDFs?
Password-protected PDFs usually fail to open here. Remove the password with a tool you trust, then add numbers.
