How to Fix Adobe Acrobat Reader Not Opening on iPad Pro

Product: Adobe Acrobat Reader
Device & OS: iPadOS (iPad Pro 12.9 3rd Generation)
Scenario: Attempting to open, view, and annotate PDF documents on an iPad Pro.
Observed behavior: The application fails to open completely despite multiple device restarts and software updates. Prior to crashing, it suffered from ongoing issues with losing saved comments and highlights.

Before you start

Verify that your iPad has sufficient storage space available and ensure your local PDF documents are backed up to iCloud or another cloud service to prevent data loss during troubleshooting.

Solution 1Recommended

Offload and Reinstall the Application

Offloading the app clears potentially corrupted cache files preventing it from launching while keeping your locally stored PDF documents intact.

When an app on iPadOS repeatedly crashes upon opening, its temporary data or configuration files may be corrupted. Rather than a full deletion, offloading the app preserves your files and settings.

Access iPad Storage

Open the 'Settings' app on your iPad Pro, navigate to 'General', and tap on 'iPad Storage'.

Locate the App

Scroll through the list of installed applications and tap on 'Adobe Acrobat'.

Offload the App

Tap the 'Offload App' button and confirm your choice. This removes the application but keeps your document data safely on the device.

Reinstall the App

Once the offloading process finishes, tap 'Reinstall App'. You can also do this by tapping the app icon on your home screen.

Data Preservation: Offloading ensures that any annotations or local PDFs that were not uploaded to Adobe Document Cloud will not be permanently deleted.

Solution 2

Check for Pending iPadOS Updates

Ensure your iPad is running the latest operating system to prevent compatibility issues with recently updated apps.

Frequently Asked Questions

Why won't Adobe Acrobat Reader open on my iPad Pro?

This commonly occurs due to corrupted application cache data, a conflicting recent iPadOS system update, or critically low device storage. Force restarting the iPad or offloading the app usually resolves the crash.

How do I prevent losing PDF highlights and comments?

To prevent annotation loss, ensure you manually save or export the document after editing, avoid leaving too many heavy background apps open, and use a highly stable PDF reader like WPS Office that actively saves your metadata.

Will I lose my local PDFs if I uninstall a crashing PDF reader?

If you completely 'Delete' the app, local files stored exclusively within that app's directory may be permanently erased. To fix crashes without losing files, always use the 'Offload App' feature in your iPad Storage settings.
