Automate Embedded Indexing via Action Wizard

Use the Action Wizard feature in Adobe Acrobat Pro to set up a custom workflow that embeds indexes into multiple files automatically.

Adobe Acrobat Pro allows you to create custom workflows using the Action Wizard tool. By adding a specific save command to a custom action, you can configure the software to embed indexes into multiple files sequentially.

Please note that the application will open and display each file during the execution of the process. For very large collections, it is highly recommended to run this action in smaller batches to prevent the software from slowing down or freezing.

1
Open the Action Wizard

Launch Adobe Acrobat Pro, navigate to the 'Tools' tab at the top of the interface, and click on 'Action Wizard'. Click 'New Action' in the toolbar to start creating your workflow.

2
Add the Save Command

In the left panel under the 'Save & Export' submenu, locate the 'Save' command and click the plus (+) icon to add it to your action steps on the right side.

3
Specify Index Settings

Underneath the newly added Save command in your workflow, click on 'Specify Settings'. A dialog box will appear; check the option for 'Embed Index' and click 'OK'.

4
Run the Batch Action

Save the action with a recognizable name. Select the action from the Action Wizard list, click 'Add Files' or 'Add Folder' to select your target PDFs, and click 'Start' to begin the automated process.

Frequently Asked Questions

Why do I need to embed an index in a PDF?

Embedding an index in a PDF drastically speeds up keyword searches within large documents or entire collections. Instead of scanning every individual word in real-time, your PDF reader references the compiled index to locate terms instantly.

Can I run the Action Wizard on an entire folder of PDFs at once?

Yes, when executing an action in Acrobat Pro's Action Wizard, you can choose 'Add Folder' to select a specific directory. The software will automatically queue and process all compatible PDF files located within that folder.

Why does my computer slow down or freeze when batch processing PDFs?

During batch processing, the software opens, renders, saves, and closes each file sequentially. Doing this for hundreds of large, graphics-heavy, or text-dense files consumes significant memory (RAM) and CPU power, which can lead to system freezes if not batched appropriately.

Will embedding an index significantly increase the PDF file size?

Embedding an index adds extra metadata and compiled text data to your document. This will incrementally increase the overall file size, though the exact amount depends on the volume of searchable text present within the original PDF.
