What stays local?

- The updated PDF before download
What should you verify?
- The first visible number is correct
- The placement does not cover page content
- Every intended page is numbered
Use the controls available in the live tool
Common Page Numbering Options
The current interface may offer one or more controls for placement, starting value and page selection.
Choose a Clear Position
Use the available top, bottom, left, center or right placement that avoids existing content.
Set the Starting Number
Begin at one or another supported value when preliminary pages should be excluded.
Apply a Page Range
Number all pages or a supported range when only part of the document needs numbering.
Improve the final document
Tips for Clean and Consistent Page Numbers
Finalize the page order first, then check the numbering against the document structure.
Before numbering
- Merge or rearrange pages into the final order
- Remove blank or unnecessary pages
- Check existing headers and footers
- Confirm the first numbered page
After numbering
- Review the first and final numbered pages
- Check pages with different sizes or orientations
- Confirm no number overlaps text or images
- Open the downloaded PDF before sharing
Practical layout guidance
What Can Affect Page Number Placement?
Page dimensions, margins and existing content can change how a number appears across the document.
| Document factor | Numbering guidance |
|---|---|
| Mixed page sizes | The same position may appear at different visual distances from page content. |
| Portrait and landscape pages | Review both orientations because a suitable position can differ. |
| Existing footer text | Choose another supported position when the footer area is already occupied. |
| Bleed or cropped edges | Keep numbers away from the edge so they remain visible when printed. |
| Cover and contents pages | Use a page range or starting number when those pages should not display standard numbering. |
| Future page changes | Rearranging, adding or deleting pages later can make the visible sequence outdated. |
