How to Delete Multiple Pages in PDF with Acrobat JavaScript
Question details
The user needs to delete a specific range of spawned pages (pages 4 to 7) in a PDF using Acrobat JavaScript, but the current code only deletes one page per click.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Automating the deletion of dynamically spawned templates in a PDF form using custom JavaScript.
- Observed behavior
- The script deletes only one page per click because it calls deletePages repeatedly in a way that is disrupted by changing dynamic page indexes.
Ensure your PDF document does not have security restrictions preventing page extraction or deletion, and save a backup copy of your PDF before running custom JavaScript.
Use the deletePages Method for a Specific Page Range
Pass the start and end page indexes into a single this.deletePages() call to remove the entire range at once without indexing conflicts.
When deleting multiple pages individually in a loop, the page indexes dynamically shift after each deletion, which causes standard loops to skip pages. By defining a range in a single command, the software handles the index shifting automatically.
Acrobat JavaScript uses zero-based indexing, meaning Page 1 is index 0. To delete the 4th through the 7th pages of your document, you need to target indexes 3 through 6.
Open your PDF form in Adobe Acrobat and navigate to the button or form field's Action properties where your current JavaScript is stored.
Replace your existing looping deletion script with the single range command: this.deletePages(3, 6);
Ensure you include the explicit document reference ('this.') in your function call so the script executes securely within the current document's context.
Save your form and click the trigger button to verify that all the intended spawned pages are removed simultaneously.

Frequently Asked Questions
Why does my Acrobat JavaScript loop fail to delete all intended pages?
Adobe Acrobat uses dynamic page indexing. When you delete the page at index 3, the page previously at index 4 immediately shifts down to become the new index 3. A standard ascending loop will effectively skip pages due to this shift. Using this.deletePages(start, end) avoids this problem entirely.
Can I delete non-consecutive pages using Acrobat JavaScript?
Yes, but you must delete them in reverse order (from the highest index to the lowest). This ensures that deleting a page at the end of the document doesn't shift the indexes of the remaining pages you intend to delete earlier in the document.
Is there a way to delete multiple pages without using JavaScript at all?
Yes. In standard PDF editors like WPS PDF, you can simply open the Page Thumbnails panel, hold Ctrl (or Command on Mac) to select multiple specific pages, and press the Delete key or click the Delete icon to remove them visually.
