Question details
The user wants to restore the automatic OCR prompt that appears when pressing Ctrl+A on an image-only PDF in Adobe Acrobat.
- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to select text using the Ctrl+A shortcut on a scanned or image-based PDF document.
- Observed behavior
- Acrobat no longer displays the prompt to run Optical Character Recognition (OCR) because the warning dialog was previously dismissed permanently.
Ensure you have an image-only or scanned PDF saved on your device to test the shortcut after resetting your application preferences.
Reset All Warnings in Acrobat Preferences
This is the most direct method to restore the OCR prompt by clearing all previously dismissed warning dialogs in Adobe Acrobat.
When you check 'Do not show this message again' on an Acrobat prompt, it is permanently hidden. Resetting your general warnings will bring back the Ctrl+A OCR prompt along with any other dialogs you may have dismissed in the past.
Launch Adobe Acrobat. Go to the 'Edit' menu at the top and select 'Preferences'. Alternatively, you can use the keyboard shortcut Ctrl+K (Windows) or Cmd+K (Mac).
In the Preferences dialog box, select 'General' from the list of Categories on the left side.
Scroll down to the 'Warnings' section. Click the 'Reset All Warnings' button and confirm your action.
Click 'OK' to close the Preferences window. Reopen your image-only PDF document and press Ctrl+A. The OCR prompt should now appear as expected.
Start OCR Manually from the Tools Menu
If you prefer not to reset all your warning preferences, you can manually trigger the OCR process whenever needed.

Frequently Asked Questions
Why did the Ctrl+A OCR prompt disappear in Acrobat?
The prompt typically disappears because the 'Do not show this message again' checkbox was selected the last time the warning appeared. Acrobat remembers this choice and permanently hides the dialog until your application warnings are manually reset.
Can I undo the 'Reset All Warnings' action?
No, there is no direct 'undo' button for resetting warnings. Once you clear them, all previously hidden prompts will be active again. You will simply need to dismiss them one by one as they naturally appear during your regular workflow.
Does pressing Ctrl+A automatically run OCR on all PDFs?
No. Pressing Ctrl+A (Select All) only attempts to select text. The OCR prompt is only triggered if Acrobat detects that the current PDF is entirely image-based and contains no renderable text to select.
How can I tell if a PDF is image-only before pressing Ctrl+A?
If you try to click and drag your cursor over words and a large blue selection box is drawn over the page instead of highlighting individual letters and sentences, the document is an image-only PDF.
