How to Recover PDF Files After Accidentally Uninstalling Acrobat Reader
Question details
The user accidentally uninstalled Adobe Acrobat Reader and needs to find a way to recover the missing PDF files that were stored within the application.

- Product
- Adobe Acrobat Reader
- Device & OS
- iOS / iPadOS
- Scenario
- The application was removed from the device by mistake, causing all associated documents to seemingly disappear.
- Observed behavior
- PDF files stored locally on the iOS device are permanently deleted when the app is uninstalled, while files synced to the cloud remain intact but require user login to access.
Before attempting recovery, check if you were logged into your Adobe account prior to the uninstallation, as this determines whether your files were securely synced to the cloud.
Recover PDFs from Adobe Document Cloud
Use this method to quickly retrieve your documents if you were signed in with an Adobe ID before the app was uninstalled.
If you previously utilized the Adobe Document Cloud to store your files, they are safely preserved on remote servers. Uninstalling the app from your device does not affect your cloud storage data.
Open the App Store on your iPhone or iPad, search for Adobe Acrobat Reader, and download the application back onto your device.
Launch the newly installed Acrobat Reader and sign in using the exact same Adobe ID credentials you used previously.
Navigate to your file list within the app. All PDF documents that were previously synced to the Adobe Document Cloud will automatically populate and be ready for use.

Restore Local Files from an iOS Device Backup
If your files were saved locally to the iPhone or iPad instead of the cloud, restoring from a previous device backup is the only way to recover them.

Frequently Asked Questions
Does uninstalling an app on an iPhone delete its files?
Yes, on iOS and iPadOS, uninstalling an application automatically deletes all locally stored files and data associated with that specific app's workspace. However, files saved to an external cloud service or the device's main 'Files' app folders remain safe.
Can I recover local PDFs if I didn't back up my iPhone?
Unfortunately, no. If the PDFs were stored locally within the Adobe Acrobat Reader app on an iOS device and no device backup was made to iCloud or a computer, the files are permanently deleted by the operating system upon uninstallation and cannot be recovered.
How can I prevent losing PDF files in the future?
To safeguard your documents, make it a habit to save your files to a cloud-based server like Adobe Document Cloud, iCloud Drive, or WPS Cloud. This ensures your files are tied to your user account rather than the physical local app installation.
Are Adobe Document Cloud files deleted when I uninstall the app?
No, files stored in the Adobe Document Cloud are securely saved on remote Adobe servers. You can regain access to them at any time from any device simply by reinstalling the app and signing back in with your Adobe ID.
