Automate Tasks Using the Action Wizard

Create a custom Action in Acrobat Pro DC to automatically process a single file, selected files, or an entire folder of PDFs.

The Action Wizard in Adobe Acrobat Pro DC is designed to streamline repetitive tasks. By building a custom action sequence, you can combine the save-as-PDF/A conversion and form-flattening commands into a single click.

1
Open the Action Wizard

Launch Adobe Acrobat Pro DC. Navigate to the 'Tools' tab at the top of the window, scroll down to the 'Customize' section, and click on 'Action Wizard'.

2
Create a New Action

Click 'New Action' in the Action Wizard toolbar. A dialog box will appear allowing you to select and sequence the tools you want to apply.

3
Add Conversion and Flattening Tools

In the left pane, expand 'Save & Export' and add the 'Save' command. Click 'Specify Settings' to configure it to save as PDF/A. Next, expand 'Document Processing' or 'Forms' to add the flattening or preflight options required to flatten form fields.

4
Specify Files and Save

In the 'Files to be Processed' section, choose whether you want the action to prompt for files or process a specific folder by default. Save the action with a descriptive name.

5
Run the Action

Select your newly created action from the Action List. Follow the on-screen prompts to batch process your selected PDFs.

Frequently Asked Questions

Why is the Action Wizard missing in my Adobe Acrobat?

The Action Wizard is an exclusive feature of Adobe Acrobat Pro DC. It is not available in Acrobat Standard or the free Adobe Acrobat Reader. You must upgrade your subscription to access automation tools.

What does flattening a PDF form actually do?

Flattening a PDF removes all interactive elements (such as fillable fields, dropdowns, and buttons) and permanently merges their visible contents with the main document layer, preventing any further edits.

Can I apply dynamic numbered stamps to multiple PDFs at once?

Yes, you can use the Action Wizard in Acrobat Pro to create an automated process that applies custom or dynamic sequential stamps across an entire folder of PDFs before saving them.

What is the difference between PDF and PDF/A?

PDF/A is a specialized, ISO-standardized version of the Portable Document Format (PDF) explicitly designed for long-term archiving and preservation of electronic documents, ensuring they can be reproduced exactly the same way in the future.
