How to Fix Adobe Acrobat Freezing When Opening or Scrolling PDFs
Question details
Adobe Acrobat Pro DC freezes or becomes unresponsive when attempting to open or navigate high-resolution PDF documents.

- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Opening or navigating a complex, high-resolution PDF, such as an exported InDesign brochure.
- Observed behavior
- The application becomes entirely unresponsive and freezes during the opening process or while scrolling through the document pages.
Before changing system preferences, open a different, plain-text PDF file to check if the freezing issue is isolated to a specific high-resolution document or if it affects all PDF files on your computer.
Disable Page Cache in Acrobat Preferences
Turning off the page cache rendering feature often resolves freezing issues caused by high-resolution images or complex document rendering.
Acrobat utilizes a page cache to speed up the display of standard documents. However, when processing unusually complex imagery or extremely high-resolution files, this memory caching can overload the application, leading to unresponsiveness.
Launch Adobe Acrobat Pro DC. On Windows, click on 'Edit' in the top menu bar. On Mac, click on 'Adobe Acrobat'. Select 'Preferences' from the dropdown menu to open the preferences dialog box.
In the left-hand pane of the Preferences window, select 'Page Display' from the list of categories.
Under the 'Rendering' section on the right side, locate the checkbox labeled 'Use Page Cache' and uncheck it.
Click the 'OK' button at the bottom to save your changes. Close Adobe Acrobat completely, restart the application, and open your high-resolution PDF to see if the scrolling has improved.

Update Acrobat and Graphics Drivers
If disabling the page cache does not work, outdated software or graphics drivers might be struggling to process complex PDF content.

Frequently Asked Questions
Why does my PDF reader freeze on high-resolution files?
High-resolution files, like exported InDesign brochures, contain complex vector graphics and massive image data. If the PDF reader's rendering cache or your computer's graphics memory is overwhelmed by this data, the application may freeze or crash while attempting to load the pages.
Does disabling 'Use Page Cache' affect overall PDF quality?
No, disabling the page cache does not change the visual quality or resolution of your PDF. It simply forces the application to render pages dynamically in real-time rather than storing them in application memory, which can prevent crashes on certain complex files.
Can I optimize a high-resolution PDF to prevent freezing altogether?
Yes. You can use a PDF editor to compress the file size, downsample image resolution, or flatten complex graphic layers. This creates a much smaller, web-optimized file that is significantly easier for standard PDF readers to process and scroll through.
What should I do if my PDF still freezes after changing the rendering preferences?
If the issue persists, ensure both your graphics drivers and PDF software are updated to their latest versions. Alternatively, try opening the document in a lightweight reader like WPS PDF to determine if the issue is software-specific or if the PDF file itself is corrupted.
