Question details

The user is experiencing an issue where Adobe Acrobat for Android deletes downloaded PDFs once the combined storage limit of 100 MB is exceeded.

How to Manage the 100 MB PDF Storage Limit in Adobe Acrobat

Product: Adobe Acrobat
Device & OS: Android
Scenario: Downloading and storing multiple PDF files locally using the Adobe Acrobat mobile app.
Observed behavior: Once the 100 MB local storage limit is reached, the app automatically deletes previously downloaded PDFs. Attempting to manually increase the data limit only works temporarily, as it resets to the default 100 MB upon restarting the app.

Before you start

Check the total file size of the PDFs currently stored in your Adobe Acrobat app to see if you are approaching the 100 MB limit, and back up any crucial documents to an external folder.

Workaround the 100 MB Limit by Managing Local Files

Since Adobe Acrobat strictly enforces a 100 MB storage limit on Android that cannot be permanently increased, you must manage your files manually to prevent automatic deletion.

The 100 MB file-size limit is a hard restriction in both the Adobe Acrobat Android app and Adobe Acrobat online services. Any changes made to the data limit in the settings will revert upon app restart.

Review stored files

Open Adobe Acrobat on your Android device and navigate to your downloaded files list to review the sizes of your current documents.

Delete unnecessary PDFs

Manually delete older or unnecessary PDF files to free up space and keep your total combined storage below the 100 MB threshold.

Redownload removed files

If a required file was already automatically deleted by the app, navigate back to the original source, email, or cloud drive and download the PDF again.

Workaround the 100 MB Limit by Managing Local Files

Hard Limitation: Because this is an inherent limitation of Adobe's software, there is no setting to permanently remove this cap within the Acrobat app.

Solution 2

Compress PDF Files to Save Space

Reduce the file size of your PDFs using a compression tool so you can fit more documents within Adobe Acrobat's 100 MB allowance.

Frequently Asked Questions

Why does Adobe Acrobat delete my downloaded PDFs on Android?

Adobe Acrobat for Android has a strict 100 MB combined storage limit for locally downloaded PDFs. When this limit is exceeded, the app automatically deletes older downloaded files to make room for new ones.

Can I permanently increase the 100 MB data limit in Adobe Acrobat?

No, you cannot permanently increase this limit. While you may be able to adjust the data limit within the app's temporary cache settings, it will revert to the default 100 MB allowance as soon as the application is restarted.

Does the 100 MB limit apply to Adobe Acrobat online as well?

Yes, the 100 MB file-size limitation also applies to Adobe Acrobat online services. Files exceeding this size will trigger an error and will need to be compressed or managed through an alternative PDF application like WPS Office.
