How to Batch Optimize Multiple Scanned PDFs in Acrobat
Product
Adobe Acrobat
Device & OS
not provided
Scenario
Managing and reducing the file size or improving the quality of numerous scanned PDF documents in a single batch.
Observed behavior
The default 'Multiple Files' option under Text Recognition lacks the necessary optimization controls for batch processing scanned PDFs.
Before you start

Ensure you are using a compatible version of Adobe Acrobat, such as Acrobat Pro, as the Action Wizard feature required for this task is not available in Acrobat Standard. Gather all the scanned PDFs you want to optimize into a single folder for easier batch processing.

Use Action Wizard to Batch Optimize Scanned PDFs

Create and run a custom batch process using the Action Wizard to optimize an entire folder of scanned documents at once.

The standard Optimize Scan option does not appear automatically for multiple files like the Text Recognition option does. To achieve batch optimization, you need to utilize the Action Wizard, which allows you to apply a custom automation action to a selected folder of PDFs.

1
Open the Action Wizard

Launch Adobe Acrobat Pro, go to the 'Tools' menu at the top, and select 'Action Wizard' from the list of available tools.

2
Select the Optimization Action

In the Action Wizard panel, click on 'Optimize Scanned Documents' from the list of available actions.

3
Choose target files or folder

Click the drop-down menu in the action window and select 'Add Folder' to choose the specific folder containing all the scanned PDFs you wish to optimize.

4
Configure enhancement settings

Under the 'Enhance' section, select 'Add Document Description' or adjust other optimization settings as required for your batch, then click 'Start' to run the action.

Frequently Asked Questions

Why can't I find the Action Wizard in my Adobe Acrobat?

The Action Wizard is an advanced automation feature exclusive to Adobe Acrobat Pro. If you are using Adobe Acrobat Standard or Adobe Acrobat Reader, this tool will not appear in your Tools menu.

Does optimizing a scanned PDF reduce its visual quality?

Optimizing a PDF generally applies compression to images to reduce file size. While it is designed to maintain readability and clean up background noise, aggressive compression settings can slightly lower the visual quality of the scanned pages.

Can I batch optimize PDFs using Acrobat Standard?

No, Acrobat Standard does not include the Action Wizard needed for batch processing. You would need to open and use the 'Optimize Scanned PDF' tool on each file individually.

What does the 'Optimize Scanned PDF' feature actually do?

It applies filters to clean up scanned images by removing backgrounds or despeckling, performs OCR to recognize text if configured, and compresses the document to make the file size smaller for easier sharing.
