Question details
The Acrobat Reader application repeatedly crashes or will not open following a recent software update.

- Product
- Acrobat Reader
- Device & OS
- iPhone or iPad
- Scenario
- Attempting to launch the Acrobat Reader app or open a PDF document after installing an app or system update.
- Observed behavior
- The application fails to launch or crashes immediately upon opening, preventing the user from accessing or reading their PDF files.
Before proceeding with reinstallation steps, ensure you have backed up any locally stored PDF files to iCloud Drive or another secure location to prevent accidental data loss.
Update, Restart, and Reinstall the Application
Apply the latest application patches and perform a clean reinstallation to resolve unexpected launch crashes.
Software updates occasionally introduce compatibility bugs that can cause an app to crash upon launch. Developers typically release hotfixes (such as Acrobat Reader version 18.09.14) to address these specific issues. Following a standard update and restart sequence can restore functionality.
Open the App Store on your iPhone or iPad, tap your Apple ID profile icon at the top right, scroll down to the 'Available Updates' section, and tap 'Update' next to Adobe Acrobat Reader if a newer version is listed.
If the app continues to crash after updating, turn off your iPhone or iPad entirely, wait approximately 30 seconds, and turn it back on to clear out any temporary system cache conflicts.
Navigate to Settings > General > Software Update on your device to ensure you are running the latest version of iOS or iPadOS, which may resolve underlying system compatibility issues.
If the issue persists, back up your local files using the Apple Files app, then long-press the Acrobat Reader icon on your home screen, select 'Remove App', and choose 'Delete App'. Finally, reinstall it fresh from the App Store.

Open and Manage PDF Files Smoothly with WPS Office
If your current PDF reader continues to crash, you can instantly regain access to your documents by using WPS Office. It provides a lightweight, highly stable, and feature-rich built-in PDF reader for iOS devices.
- 1. Download WPS Office: Search for WPS Office in the Apple App Store and download the application to your iPhone or iPad.
- 2. Launch the Application: Open WPS Office and grant the necessary file access permissions so the app can locate your documents.
- 3. Locate Your PDF Files: Tap on the 'Files' tab at the bottom of the screen to browse your device's local storage or connected iCloud drive.
- 4. Open and Read: Tap on the PDF file you wish to view. It will immediately open in the stable WPS PDF viewer, where you can read, highlight, or annotate without interruption.

Frequently Asked Questions
Why does Acrobat Reader keep crashing right after an iOS update?
System updates can sometimes alter core device frameworks, causing older application versions to conflict with the new system architecture. App developers release subsequent patches to align their software with the new iOS version and resolve these crashes.
Will I lose my PDF files if I uninstall Acrobat Reader to fix the crash?
Yes, if your files are saved exclusively in the 'On My iPhone/iPad' local folder for Acrobat and are not synced to Adobe Document Cloud or iCloud, deleting the app will erase those files. Always back them up manually via the Apple 'Files' app first.
How can I back up my PDFs if the Acrobat app refuses to open?
You do not need to open the app to back up local files. Open the default Apple 'Files' app on your device, navigate to 'On My iPhone' or 'On My iPad', open the 'Acrobat' folder, select your PDF files, and move or copy them to your 'iCloud Drive' folder.
