Solution 1Recommended

Adjust Reading Preferences in Acrobat

By changing the screen reader options to only process visible pages, you can bypass the document preparation delay for large files.

Adobe Acrobat includes built-in accessibility features that scan and prepare documents for screen readers. While helpful for accessibility, this background processing can cause significant delays when opening large PDF files.

1
Open Acrobat Preferences

Launch Adobe Acrobat, click on 'Edit' in the top menu bar, and select 'Preferences' from the drop-down menu. Alternatively, you can use the keyboard shortcut Ctrl+K (Windows) or Cmd+K (Mac).

2
Navigate to Reading Settings

In the Preferences dialog box, locate the 'Categories' pane on the left side and click on 'Reading'.

3
Modify Screen Reader Options

Look for the 'Screen Reader Options' section. Open the drop-down menu next to 'Page vs Document' and select 'For large documents, only read the currently visible pages'.

4
Save and Restart

Click the 'OK' button to apply the changes. Close and restart Adobe Acrobat, then open a large PDF to verify that the progress window no longer appears.

Frequently Asked Questions

Why does Acrobat say 'preparing document for reading'?

This message appears because Acrobat's built-in Screen Reader or Accessibility feature is scanning the document to tag its structure and text for text-to-speech tools. For large files, this scanning process takes noticeable time.

Will changing reading preferences affect my ability to edit or print?

No, adjusting the reading preferences only affects how Acrobat processes the document for accessibility tools like screen readers. It does not alter your ability to view, edit, print, or save the PDF.

Can I completely disable accessibility features in Adobe Acrobat?

While you cannot completely uninstall the accessibility module, you can effectively bypass the delays by setting the Screen Reader Options to 'Only read the currently visible pages' and disabling Assistive Technology support in the Accessibility preferences.

Does this issue happen with all PDF viewing software?

No, the 'Document Preparation Progress' window is specific to Adobe Acrobat's accessibility processing engine. Lightweight alternatives like WPS Office PDF reader are designed to open documents instantly without this specific delay.
