What this tool does
It writes a page number onto each page of your PDF, in the footer or the header, and saves the result as a new file. You choose the corner, the wording, the size and how far the number sits from the edge. The preview shows any page with its number exactly where it will be in the saved file, so you can flip through before you download.
- Formats: a plain number, "Page 1", "Page 1 of 12", "1 / 12" or "- 1 -".
- Start on page: leave a title page or table of contents without a number.
- First number: continue a count from another document, for example starting at 25 for a second part.
- Double-sided: keeps left and right numbers on the outer edge when you print on both sides.
Common page numbering setups
| Document | Settings |
|---|---|
| Report or thesis with a title page | Bottom center, "1", start on page 2 with first number 1 |
| Printed booklet, both sides | Bottom right, "Page 1", double-sided on |
| Contract or offer | Bottom right, "Page 1 of 12", so a missing page stands out |
| Second part of a longer document | Any corner, first number set to where part one ended plus one |
| Slides exported as PDF | Bottom right, "1 / 12", small size, close to the edge |
About the font
Numbers are set in Helvetica. The tool refers to the font by name instead of packing a font file into your PDF, so the saved file is only a few kilobytes larger than the original.

Frequently asked questions
Is my PDF uploaded?
No. Your browser opens the PDF, adds the numbers and saves a new copy on your device. The file never leaves your computer or phone.
Can I leave the cover page without a number?
Yes. Set "Start on page" to 2. The second page then gets the first number. Set "First number" to 2 as well if the cover should still count.
What does "Double-sided" do?
For documents printed on both sides, numbers on the left or right switch sides on even pages, so they always sit on the outer edge of the paper. Odd pages keep the side you picked.
Do rotated or landscape pages get the number in the right place?
Yes. The tool reads how each page is turned and places the number where you see the bottom or top of the page, upright and readable.
Will links, bookmarks and form fields still work?
Yes. The numbers are drawn onto the existing pages of your PDF, so everything else in the file stays as it was.
