How to Stop Acrobat Pro from Automatically Running OCR on Scanned PDFs
Question details
The user needs to stop Adobe Acrobat Pro DC from automatically running OCR (Optical Character Recognition) and deskewing scanned pages.

- Product
- Adobe Acrobat Pro DC
- Device & OS
- macOS
- Scenario
- Scrolling through scanned PDF documents where the user only wants to view the pages without altering the original image quality or text.
- Observed behavior
- Acrobat Pro DC continuously runs background text recognition and distorts the document by deskewing it, despite the 'Recognize Text' option being unchecked in the software settings.
Ensure you have saved all open documents in Acrobat Pro and have administrative access to your Mac, as these troubleshooting steps may require a system restart or software reinstallation.
Restart Your Mac and Re-verify OCR Settings
Application preferences may fail to save into your system's temporary memory. A simple restart can force Acrobat to acknowledge the updated settings.
In many cases, the setting is toggled in the user interface but fails to register in the backend configuration due to cached data. Restarting clears this cache.
Save your work and completely quit Adobe Acrobat Pro DC by pressing Cmd + Q.
Click the Apple menu in the top left corner of your screen and select 'Restart'.
Reopen Acrobat Pro, navigate back to the scanner or document preferences, and ensure that the 'Recognize Text' option remains unchecked.
Temporarily Disable Enhanced Security for Testing
Document-specific security restrictions can sometimes interfere with how Acrobat applies user preferences to specific files.
Perform a Clean Reinstallation of Acrobat Pro
If the issue started after installing a recent update, corrupted installation files may be preventing settings from being saved.
Manage Scanned PDFs Without Unwanted Modifications Using WPS Office
If Adobe Acrobat continues to force unwanted OCR and distort your documents, consider switching to WPS Office. The WPS PDF editor strictly keeps OCR as a manual tool, ensuring your scanned documents load quickly and remain completely unaltered while you read or scroll.
- 1. Open your scanned PDF: Launch WPS Office and open your scanned document in the WPS PDF viewer.
- 2. Scroll without lag: Read and scroll through your document smoothly without background OCR processes freezing the application.
- 3. Manually apply OCR: When you actually need to extract text, navigate to the 'Tools' tab and click 'OCR'.
- 4. Extract specific text: Select the specific pages or regions you wish to convert, keeping the rest of the document visually pristine.

Frequently Asked Questions
Why does Acrobat Pro deskew distort my scanned PDF pages?
When Acrobat's automatic OCR runs, it attempts to digitally straighten (deskew) text it perceives as crooked. If the scanned background contains complex images, shadows, or irregular text alignments, this automated process can severely distort the original page layout.
Can I permanently turn off OCR completely in Adobe Acrobat DC?
Yes, you can uncheck 'Recognize Text' in Acrobat settings. However, due to occasional software bugs or permission errors on macOS, the application may fail to save this preference, requiring you to clear your preferences or reinstall the software.
Is OCR strictly necessary for viewing scanned PDFs?
No. OCR is only required if you want to make the text inside the scanned image selectable, searchable, or editable. For simply viewing, printing, or sharing, standard image-based PDFs are perfectly adequate and often load faster.
