How to Restore Adobe Acrobat's OCR Prompt for Scanned PDFs
Question details
The user wants to restore the automatic OCR prompt that previously appeared when attempting to search for text within a scanned, image-only PDF.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Searching for specific words or phrases in a scanned PDF document that lacks a recognized text layer.
- Observed behavior
- The prompt offering to run OCR and make the document searchable no longer appears, even after the user reset the application's warning messages.
Before troubleshooting, verify whether your document is genuinely an image-based scan without a text layer, and check if you are using the standard 'Find' tool or 'Advanced Search'.
Manually Run the Scan & OCR Tool
If the automatic prompt fails to trigger, you can manually initiate the OCR process to recognize text and make your document searchable.
Instead of relying on the automatic pop-up prompt, Adobe Acrobat provides a dedicated tool to convert scanned document images into searchable text. This ensures your search functions work perfectly regardless of prompt behavior.
Open your scanned PDF in Adobe Acrobat, navigate to the 'Tools' menu at the top, and select 'Scan & OCR'.
Click on 'Recognize Text' in the toolbar and select 'In This File' from the dropdown menu.
Choose the primary language of the document and click the 'Recognize Text' button to process the file.
Once the process is complete, press Ctrl+F (or Cmd+F on Mac) to search for your desired text.
Check Preferences and Update Acrobat
Updating the software and repairing the installation can fix bugs related to missing dialog prompts.

Frequently Asked Questions
Why did my OCR prompt disappear in the first place?
This can happen if you previously checked a 'Do not show again' box on the prompt, if a recent software update altered default search behaviors, or if your application's preference files became corrupted.
What is the difference between Find and Advanced Search in PDFs?
The 'Find' tool (Ctrl+F) quickly searches the active document, while 'Advanced Search' (Shift+Ctrl+F) provides comprehensive options to search across multiple PDFs in a directory. Sometimes, the OCR prompt behaves differently depending on which search method you initiate.
Does OCR work on handwritten text in scanned PDFs?
Standard OCR engines are optimized for typed or printed text. While they can recognize exceptionally clear block letters, standard OCR generally struggles to accurately convert cursive or messy handwriting into searchable text.
