How to Stop Acrobat from Converting PDFs for Reading or Accessibility
Question details
The user wants to prevent Adobe Acrobat from automatically processing documents for text reading or accessibility every time a PDF is opened.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Opening a PDF document in the Adobe Acrobat application.
- Observed behavior
- Acrobat begins processing the document for reading or accessibility, triggering a progress prompt that disrupts the workflow.
Ensure that your Adobe Acrobat application is open and temporarily disable any active third-party screen reading software to verify it isn't forcing Acrobat into accessibility mode.
Adjust Acrobat Reading Preferences
Change the Page vs. Document setting in Acrobat's Reading Preferences to stop it from processing the entire document for screen readers upon opening.
By default, Acrobat may attempt to prepare the entire document for assistive technologies. Limiting this to only the currently visible pages stops the lengthy background conversion process.
Launch Adobe Acrobat. Click on 'Edit' in the top menu bar (or 'Acrobat' if you are on a Mac), and select 'Preferences' from the drop-down menu.
In the Preferences dialog box, look at the categories on the left-hand pane and click on 'Reading'.
Locate the 'Screen Reader Options' section. Find the 'Page vs Document' drop-down menu and change the selection to 'Only read the currently visible pages'.
Click 'OK' to save your changes. Close the application and reopen your PDF document to verify that the accessibility processing prompt no longer appears.

Frequently Asked Questions
Why does Acrobat always show the 'Preparing document for reading' message?
This message appears when Acrobat attempts to analyze an untagged PDF document to build a structure tree for screen readers. This is triggered either by its default preference settings or by assistive technology running on your operating system.
Does disabling this reading feature affect my PDF's actual text or layout?
No. Changing the reading preferences only stops Acrobat from processing the document structure for screen readers in the background. The visual layout, text, fonts, and formatting of your PDF remain completely unchanged.
What if changing the reading preferences doesn't stop the processing pop-up?
If the prompt persists after changing the settings, check your computer for active assistive technologies. Tools like Windows Narrator, Magnifier, or third-party screen readers can force Acrobat to override its internal settings and prepare the document anyway.
Can I permanently disable the accessibility module in Adobe Acrobat?
While Adobe Acrobat does not offer a straightforward toggle to completely disable its accessibility core, restricting the reading settings to 'Only read the currently visible pages' is the official and most effective method to stop automatic document processing.
