Scenario
Attempting to merge multiple PDF documents or compress a large PDF file using the Acrobat Reader mobile app.

Solution 1Recommended

Clear App Cache and Update Acrobat Reader

Clearing temporary files and ensuring you have the latest app version can resolve cloud processing glitches causing the pending state.

Acrobat Reader Mobile relies on cloud services to merge and compress PDFs. If the app's cache becomes corrupted or if there is a bug in an older version, the communication with the cloud server might hang.

1
Force stop the app

Close the Adobe Acrobat Reader app completely from your recent apps menu.

2
Clear app cache

On Android, go to Settings > Apps > Acrobat > Storage and tap 'Clear Cache'. On iOS, you may need to offload or reinstall the app.

3
Check for updates

Open the Google Play Store or Apple App Store, search for Adobe Acrobat Reader, and install any available updates.

4
Re-login to your account

Open Acrobat, go to Profile > Sign Out, and then sign back in to refresh your connection to the Adobe Document Cloud.

Clear App Cache and Update Acrobat Reader
Check specific files: If the problem persists, test the app with a different, much smaller PDF file to isolate whether the issue is app-wide or specific to one corrupted document.

Frequently Asked Questions

Why do my PDF files get stuck on pending when merging on mobile?

This usually happens due to unstable internet connections or server-side delays when the app tries to upload, process, and download files from the cloud server.

Does file size affect the pending time during compression?

Yes. Unusually large PDFs or files containing high-resolution images take significantly longer to upload and process, which can sometimes cause the cloud conversion task to hang indefinitely.

Will I lose my original file if the merged version stays on pending forever?

No, your original PDF files remain completely safe and intact on your device or cloud storage. The pending status only affects the new output file being generated.
