- Product
- Adobe Acrobat and Reader
- Device & OS
- not provided
- Scenario
- Adding text to a PDF document using the Fill and Sign feature.
- Observed behavior
- The application becomes unresponsive, freezes, or hangs indefinitely during the text addition process.
Before making system changes, try using a different PDF file to rule out document corruption, and ensure the file is saved to your local drive rather than accessed directly from a shared network folder.
Update and Repair the Acrobat Installation
Installing the latest software updates and repairing the program files can resolve underlying software corruption that causes the application to freeze.
Running outdated software or having corrupted installation files are common culprits for performance issues in PDF editors.
Open the application, navigate to the 'Help' menu, and select 'Check for Updates'. Install any pending updates and restart your computer.
Go to the 'Help' menu and click on 'Repair Installation'. Allow the process to complete, then restart your computer.
Click 'Help' > 'About Acrobat' to ensure your software is updated to the latest available build.

Temporarily Disable Protected Mode (Windows)
Strict security settings can sometimes interfere with editing tools. Disabling them temporarily can help isolate the cause of the freezing.
Use the Online Document Cloud Tool
If the desktop application continues to freeze, you can use the web-based version of the tool as an immediate workaround to finish filling out your document.

Frequently Asked Questions
Why does my PDF application only freeze on specific files?
Certain PDF files may be corrupted, excessively large, or contain complex interactive elements and heavy formatting that overwhelm the application's memory when trying to add new text.
Can working from a network drive cause the Fill and Sign tool to hang?
Yes, network latency, temporary connection drops, or restricted file permissions can interrupt the read/write process, causing the software to freeze. It is always recommended to download and save the PDF to your local computer before editing.
How do I re-enable Protected Mode after troubleshooting?
To restore your security settings, go to Edit > Preferences, select Security (Enhanced) from the left pane, and check the boxes for both 'Enable Protected Mode at startup' and 'Enable Enhanced Security', then restart the application.
Are there free alternatives to fill out a PDF without freezing?
Yes, you can use lightweight, dedicated alternatives like WPS PDF or web-based tools which consume fewer system resources and provide smooth text insertion and form-filling capabilities.
