Can Acrobat Batch-Add and Replace Text with Bold Formatting in PDF?
Question details
The user wants to know if they can process thousands of PDF files to add text in a fixed location and replace existing regular text with bold text using Acrobat Action Wizard or JavaScript.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Automating text insertion and formatting modifications across a large batch of PDF documents via scripting or wizards.
- Observed behavior
- Acrobat JavaScript cannot directly edit static text content. It can only add elements like watermarks or form fields, making find-and-replace for text formatting highly complex and unsuited for simple batch operations.
Because Acrobat JavaScript cannot natively edit underlying static text, attempting batch text replacements requires complex workarounds; ensure you test any Action Wizard script on a small copy of your PDFs first.
Using Acrobat Action Wizard Workarounds for Text Manipulation
While direct static text editing is impossible via JavaScript, you can use Acrobat's batch tools to add text via watermarks and use a redaction workaround to replace existing text.
Acrobat JavaScript is designed to interact with interactive elements (like form fields, comments, and annotations) rather than the base static text layer of a PDF. Because of this architectural limitation, you cannot run a simple script to 'find and replace' regular text with bold text.
To achieve a similar result, you must rely on a multi-step workaround: batch-applying watermarks to add new text, and using the redaction tool to obscure old text before overlaying a new form field with bold formatting. This process is highly complex and not recommended for thousands of files without extensive custom scripting.
Open Adobe Acrobat and navigate to Tools > Action Wizard > New Action. In the left pane under 'Pages', add the 'Add Watermark' tool to your action steps to insert fixed-location text across multiple PDFs.
To remove the text you wish to replace, use the 'Search & Remove Text' (Redaction) tool to find specific words and apply redaction marks, effectively erasing the original text.
Write a custom JavaScript within the Action Wizard to generate new text field annotations over the redacted areas. Set the text field properties to use a bold font, and then flatten the document to make the text permanent.

Easily Edit and Format PDF Text with WPS Office
While batch-scripting text replacements in Acrobat is heavily restricted and complex, WPS Office offers a highly intuitive PDF Editor. You can easily modify existing text, apply bold formatting, and insert new content exactly where you need it without relying on complicated JavaScript workarounds.
- 1. Open Your PDF in WPS Office: Launch WPS Office, click on 'PDF' in the home screen, and open the document you wish to modify.
- 2. Enable PDF Edit Mode: Navigate to the 'Edit' tab at the top of the screen and click 'Edit Content' to make the document's static text selectable.
- 3. Format or Replace Text: Highlight the regular text you want to change and use the floating toolbar to apply bold formatting, or simply type to replace the text entirely.
- 4. Add New Text Blocks: Click 'Insert Text' from the Edit tab to draw a new text box anywhere on the page and type your fixed-location text.

Frequently Asked Questions
Can Acrobat Action Wizard automatically find and replace text in multiple PDFs?
No, Adobe Acrobat does not feature a native 'find and replace' function for modifying static text content across multiple PDFs. You can search and redact text in batches, but replacing it with new formatted text requires advanced workarounds.
Why can't Acrobat JavaScript directly edit static PDF text?
Static text in a PDF is embedded in the document's base content stream to ensure exact visual reproduction. The Acrobat JavaScript API is only designed to manipulate interactive layers, such as form fields, annotations, and bookmarks, rather than altering the base text layer.
Is there a simple way to batch add fixed text to thousands of PDFs?
Yes, if you only need to add text (and not replace existing text), you can easily use Acrobat's Action Wizard. Create a new action and include the 'Add Watermark' or 'Add Header & Footer' tool to stamp the same text in a fixed location across all selected files.
