Disable Automatic Thumbnail Embedding in Preferences
Disabling background page rendering features can significantly reduce the processing load and prevent Acrobat from freezing during document navigation.
Acrobat attempts to render thumbnails and page caches in the background by default. On some systems, this continuous processing causes the entire application to become unresponsive.
Launch Adobe Acrobat DC, click on 'Edit' in the top menu bar, and select 'Preferences' from the dropdown menu (or press Ctrl+K).
In the left-hand pane of the Preferences window, click on the 'Page Display' category.
Under the Rendering section, uncheck 'Use page cache'. Additionally, disable any settings related to the automatic embedding of thumbnail pages.
Click 'OK' at the bottom of the window to apply the changes, then fully close and restart Adobe Acrobat DC to see if performance has improved.
Remove Conflicting Creative Cloud Components
Uninstalling unnecessary background components linked to Adobe Creative Cloud can free up system resources and stop conflicts with Acrobat.
Reset Acrobat Preferences and Update Software
Corrupted preference files or missing bug fixes can lead to severe application unresponsiveness.
Experience Lightning-Fast PDF Editing with WPS Office

Frequently Asked Questions
Why is Adobe Acrobat DC suddenly acting so slow?
Sudden slowness in Acrobat DC is often caused by a bloated page cache, conflicting background processes from Adobe Creative Cloud, or corrupted temporary preference files overloading your system's memory.
Does disabling the page cache in Acrobat reduce document quality?
No, disabling the page cache does not affect the visual quality of your PDF. It simply forces the application to render pages as you scroll rather than pre-loading them into memory, which can drastically improve responsiveness on struggling systems.
Will reinstalling Adobe Acrobat DC fix freezing issues?
A clean installation can fix freezing if the issue stems from corrupted installation files. For the best results, use the official Adobe Acrobat Cleaner Tool to wipe leftover registry entries before reinstalling the software from scratch.
