Question details
The user needs to update the underlying Illustrator artwork of a PDF without losing the interactive form fields and scripts previously added.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Modifying the design of a large PDF form after form fields and scripts have already been created.
- Observed behavior
- The user wants to replace the page background and artwork seamlessly, avoiding the need to manually recreate form elements.
Ensure you have saved a backup copy of your original interactive PDF form before replacing pages, just in case the layout shifts significantly during the update.
Use the Replace Pages Feature in Adobe Acrobat
Use the Replace Pages feature in Acrobat to swap the old background with the newly exported PDF while keeping interactive elements intact.
This method ensures that only the base artwork of the PDF is updated. All interactive overlays, such as form fields, buttons, and embedded JavaScript, are preserved on the document layer.
Edit your original file in Adobe Illustrator and export the updated version as a new PDF document.
Open your original, interactive PDF form (the one containing the fields and scripts) in Adobe Acrobat.
Navigate to the 'Tools' menu and select the 'Organize Pages' tool.
Click the 'Replace' option from the top toolbar, select your newly exported Illustrator PDF, specify the page range to swap, and click 'OK'.

Manage PDF Pages and Forms with WPS Office
WPS Office includes a comprehensive PDF editor that allows you to replace pages, edit text, and modify PDF designs seamlessly without losing your interactive elements.
- 1. Open your PDF: Launch WPS Office and open your interactive PDF form in the PDF Editor.
- 2. Navigate to Page tools: Go to the 'Page' tab located on the top navigation ribbon.
- 3. Replace the page: Click 'Replace Page', select the updated PDF design file from your computer, and confirm the action to swap the background.

Frequently Asked Questions
Will replacing pages in Acrobat delete my JavaScript actions?
No, replacing pages only swaps the base content (the background design). Any document-level JavaScript, form fields, and field-level scripts will remain completely intact.
What if the new Illustrator design changes the position of the form boxes?
You will need to manually drag and drop the existing form fields in your PDF editor to align them with the new visual layout. The fields themselves will not be deleted, but they do not automatically snap to new background graphics.
Can I edit the Illustrator PDF directly in Acrobat without replacing pages?
Yes, for minor text or image changes, you can use the 'Edit PDF' tool directly in Acrobat. However, for large structural changes, updating the source Illustrator file and replacing the PDF pages is much more efficient and maintains image quality.
