Fix Adobe Acrobat Slow to Open PDFs After iPhone Update
Question details
The user is experiencing performance issues where PDF files take too long to load or freeze the application entirely.
- Product
- Adobe Acrobat
- Device & OS
- iPhone, iOS 13.2.3
- Scenario
- Trying to open and read PDF plans on an iPhone using Adobe Acrobat after a recent iOS system update.
- Observed behavior
- PDF plans load very slowly, and the app freezes and becomes unresponsive, even after the user has tried reinstalling the app and restarting the device.
Ensure your iPhone has sufficient free storage space and check the App Store to verify you have installed the absolute latest version of Adobe Acrobat available for your iOS version.
Clear App Cache and Device Data
Clearing accumulated or corrupted cached data can resolve conflicts introduced during an OS update and restore app performance.
While reinstalling an app often helps, some residual cached data might remain on the device or in the cloud. Clearing this data specifically can help stop the freezing behavior when opening large PDF plans.
Navigate to your iPhone's home screen and tap the 'Settings' app, then tap on 'General'.
Tap on 'iPhone Storage' and wait for the app list to load. Scroll down to find and select 'Adobe Acrobat'.
Tap 'Offload App'. This clears the app's execution cache while keeping your documents safe. Once completed, tap 'Reinstall App'.
If you can open the app briefly without it freezing, go to the Adobe Acrobat profile settings and look for the 'Clear Cache' option inside the app preferences.
Download the PDF Locally Before Opening
Opening large PDF plans directly from cloud services (like iCloud or Adobe Document Cloud) can cause the app to hang if the connection drops.

Frequently Asked Questions
Why are my PDF files freezing on my iPhone after an iOS update?
iOS updates can occasionally introduce compatibility issues with third-party apps. Additionally, corrupted cache data from previous app versions might conflict with the new OS environment, causing heavy files like PDF plans to freeze during rendering.
How do I clear the cache of a specific app directly on an iPhone?
iOS does not have a universal 'Clear Cache' button for all apps. To clear cache, you can navigate to Settings > General > iPhone Storage, select the app, and choose 'Offload App'. Some apps also offer an internal 'Clear Cache' button within their own settings menu.
Does the size and complexity of a PDF affect how fast it opens on a mobile device?
Yes. PDF files containing high-resolution images, complex vector graphics, or large architectural plans require significant processing power and RAM to render. If your device is low on available memory or if the app isn't fully optimized, these files will load slowly or cause the app to crash.
