- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Adding alternate text to images or elements within a combined PDF document for accessibility purposes.
- Observed behavior
- The application completely freezes without displaying any error messages, forcing the user to manually close the program via the task manager.
Before proceeding, ensure you have saved a backup copy of your combined PDF to your local hard drive, as working over a network connection can sometimes cause document processing hangs.
Update Adobe Acrobat to the Latest Version
Installing the latest patch updates often resolves known software bugs, such as application freezing during accessibility tagging.
Software versions like Acrobat DC 2019 (e.g., build 19.12.20035) often have documented bugs related to document structure and accessibility features. Updating to a newer build (like 19.12.20036 or later) is the most effective way to eliminate these silent freezes.
Launch the application without opening the problematic combined PDF file.
Click on 'Help' in the top menu bar of the application.
Select 'Check for Updates' from the drop-down list. The Adobe Updater will scan for available patches.
Follow the on-screen prompts to download and install the update. Once finished, restart Acrobat and try adding alternate text to your file again.
Isolate the Issue to the File or Network
Determine whether the freeze is caused by network latency or file-specific corruption rather than the application itself.

Frequently Asked Questions
Why does a PDF editor freeze when handling combined files?
Combined PDFs often contain complex, overlapping document tags, conflicting fonts, or heavy media compiled from multiple sources. When you try to modify the document structure (such as adding alternate text), the software can become overwhelmed and freeze if it lacks sufficient memory or runs into a structural bug.
How can I force-close my PDF application if it freezes completely?
On Windows, press Ctrl + Shift + Esc to open the Task Manager, locate the unresponsive application in the Processes tab, right-click it, and select 'End task'. On macOS, press Option + Command + Esc, select the application from the list, and click 'Force Quit'.
Does WPS Office support editing PDF documents natively?
Yes, WPS Office includes a robust built-in PDF toolkit. It allows users to view, edit text, add images, merge multiple PDFs, and convert them to or from Word, Excel, and PowerPoint formats effortlessly.
