Question details

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Adding or modifying page numbers in a PDF document to adhere to a specific stylistic or corporate branding requirement.
- Observed behavior
- The built-in page numbering macro only provides a lowercase "of" option, lacking a native dropdown selection for an uppercase "OF".
Verify that your PDF editing software supports JavaScript execution or custom text fields in Headers and Footers, as standard PDF readers lack the ability to alter page number macros.
Use a Custom JavaScript to Format Page Numbers
Because the built-in macro does not support uppercase "OF", running a custom JavaScript is the most efficient way to automate the "1 OF n" format across all pages.
Advanced PDF editors allow users to execute document-level JavaScripts. By running a simple loop script, you can generate custom text fields on every page that dynamically pull the current page number and the total page count, separated by an uppercase "OF".
In your PDF editor (such as Acrobat Pro), navigate to the Tools menu, find the JavaScript section, and open the Document JavaScripts or Debugger console.
Enter a script that loops through 'this.numPages'. The script should use the 'addField' method to place a text box on each page containing the string: (i + 1) + " OF " + this.numPages.
Run the script to automatically stamp the custom page number format in the designated coordinates on every page of your PDF document.
Manually Insert Text via Headers and Footers
For shorter documents where scripting is not feasible, you can use the Header & Footer tool to manually insert customized text on specific page ranges.

Frequently Asked Questions
Can I change the font style and size of PDF page numbers?
Yes. When adding page numbers through the Header & Footer dialog in your PDF editor, you can select the text and adjust the font type, size, color, and alignment before applying it to the document.
Why can't I edit existing page numbers in my PDF?
Existing page numbers might be flattened into the document's background or embedded as image elements rather than text. You may need to use an OCR (Optical Character Recognition) tool or manually crop them out before adding new page numbers.
Is it possible to start page numbering from page 2 or 3?
Yes. Most advanced PDF editors feature 'Page Range Options' within the Header and Footer settings. You can specify exactly which pages should receive the numbering, effectively skipping the cover or table of contents pages.
Does WPS PDF support Bates numbering for legal documents?
Yes, WPS PDF provides Bates numbering features designed for legal and professional documents, allowing you to add unique prefixes, suffixes, and sequential numbers across multiple PDF files simultaneously.
