- Nine placement options on every page: bottom center for reports, corners and edges for dense layouts
- Formats for any convention: plain digits, Page X, X / Y with the total, or your own prefix and suffix, like "Page " or "- 5 -"
- Start numbering at page 2 or 3: covers and tables of contents stay unnumbered, the standard for theses, reports and bid documents
- Bottom positions place numbers in the footer margin, following the book convention of page numbers near the outer edge when printed
- Adjust the font size and color of the numbers to match your document's headings or footers
- Live preview on the page thumbnail shows the exact number and position before you export
- Original pages are copied without recompression: text, images and links stay untouched, only the number is drawn
- Works with scanned PDFs: numbers are drawn over the image of every page
How to Use
- 1Click the drop zone or drag the PDF onto the page to open it
- 2Pick a position on the nine-grid: bottom center suits most reports, bottom right is common for contracts
- 3Choose a format: plain digits, Page X, X / Y, or custom
- 4In the custom format, type the prefix and suffix yourself: a prefix "Page " gives "Page 5", prefixes and suffixes "- " and " -" give "- 5 -"
- 5Set the starting page: enter 2 so the cover stays unnumbered and page 2 becomes number 1, the standard for theses
- 6Adjust the font size and color of the numbers
- 7Check the live preview on the page thumbnail
- 8Click Add page numbers, then Save PDF to export the numbered document
- 9Thesis example: X / Y format, bottom center, numbering starting at the first page after the cover and contents
- 10Bid or contract example: start at page 2 to skip the cover, plain digits in the bottom right
- 11Printing example: choose a bottom position so the number lands in the footer margin of the printed sheet
Frequently Asked Questions
How do I add page numbers to a PDF?
Open the PDF in the tool, pick a position from the nine-grid, choose a format, and click Add page numbers. Then save the numbered PDF with one click.
Can I start numbering from page 2 or 3?
Yes. Set Start numbering at to 2 or 3. Starting at 2 makes page 2 show number 1 while the cover stays unnumbered, the standard for theses and reports. Starting at 3 also leaves the table of contents blank, the usual layout for bid documents that open with a contents page.
Can I add page numbers to a PDF without Adobe Acrobat?
Yes. Everything runs in your browser, so there is nothing to install or sign up for: open the PDF, configure the numbering, and save the result on any device. It works as a complete online alternative to Acrobat for numbering.
Can I use a custom prefix or suffix, like "Page "?
Yes. In the custom format you type the prefix and suffix yourself: a prefix "Page " produces "Page 5", and a prefix "- " with a suffix " -" produces "- 5 -", which is common in reports and handouts.
What number formats are supported?
Plain digits (1, 2, 3), "Page X" style, "X / Y" with the total page count, and a custom format with your own prefix and suffix around the number.
Will adding page numbers change my PDF?
No. Only a number is drawn in the chosen spot on each page; the original content is not recompressed or altered. Text, images and links stay exactly as they were.
What if a page number overlaps the body text?
On dense pages the middle positions can sit on top of text. Switch to a bottom or corner position, or reduce the font size: the footer area is usually empty, so bottom positions rarely overlap.
Do the numbers print correctly when I print the PDF?
Yes. A bottom position places the number in the footer margin of the printed sheet, close to where book conventions put page numbers; for double-sided booklets, the bottom-outer corners match the outer-edge placement used in books.
Can I change the position, font size or color?
Yes. Nine positions are available (bottom left, bottom center, bottom right, middle left, middle center, middle right, top left, top center and top right), and both font size and color are adjustable.
Can I number scanned PDFs?
Yes. Scanned PDFs are image-based documents and the page number is drawn on top of each page just like with any other PDF.
How do I add page numbers in Adobe Acrobat?
In Adobe Acrobat Pro, open the file, then use Tools > Edit PDF > Header & Footer > Add: pick the font, position, and the 'Page X of Y' style, choose the page range, and apply. Two honest caveats: the free Acrobat Reader cannot add page numbers at all (no Edit PDF tools), and Acrobat Pro is a paid subscription. If you do not have Pro, this tool adds numbers with the same result in any browser.
Can I add page numbers to a PDF on a Mac?
With the built-in tools, no. Preview cannot add page numbers (it is a viewer with basic annotations, no header/footer editing). Your options: Adobe Acrobat Pro (paid), or any browser-based tool like this one, which runs identically on macOS and needs no installation. The numbered output is a standard PDF that Preview opens normally afterwards.
Can I number multiple PDFs?
The tool processes one PDF at a time. For several files, number each one in turn; the process takes only a few seconds per document.
Does it work on mobile devices?
Yes, the tool is fully responsive. On a phone or tablet, open a PDF from the Files app, pick the position and format, and save the numbered document.
Why does my printed page show a different number than expected?
This happens when you start numbering from a page other than the first. For example, starting from page 2 means the physical page 2 displays number 1, page 3 displays 2, and so on. The tool shows a preview of the first numbered page before you save, so check it if the numbering looks off.
Why is the first page not numbered?
If you selected 'start from page 2' or later, the tool intentionally skips the earlier pages; this is the standard layout for reports and books with a cover page or table of contents. To number every page including the first, choose 'start from page 1'.
Why can't I add page numbers to a pdf online if the file is password-protected?
Encrypted PDFs refuse writes from any tool unless the password is supplied first: browsers do not even render them without the owner password. Unlock the file in your PDF reader first (or use an unlock tool), then add page numbers to the decrypted copy. This is a PDF-standard restriction, not a tool limitation.
Why can't I add page numbers to pdf free without a watermark on other sites?
Server-based sites stamp watermarks to push paid plans. This tool renders and writes the PDF entirely in your browser, so there is nothing to monetize. The numbered output contains only the numbers you chose: no watermark, no footer banner, no page limit beyond your device's memory.
