How to Fix Adobe Scan Cannot Save a Document With More Than 160 Pages

Product: Adobe Scan
Device & OS: iOS
Scenario: Trying to save a large, multi-page scanned document directly from the mobile scanning application.
Observed behavior: The application fails to save the document, which may be caused by memory limitations, file size constraints, insufficient storage space, or an application bug.

Before you start

Ensure your device has at least 1-2 GB of free storage space to handle the processing of large, high-resolution PDF files before attempting to save the scan.

Solution 1Recommended

Save the Scan as Multiple Smaller Documents

Splitting the large scan into smaller batches avoids hitting the app's memory constraints and ensures successful saving.

Mobile scanning applications often struggle to process and save documents that exceed a certain number of pages due to device RAM limitations. By dividing the workload, you can safely export your pages without losing your scanned data.

Select a subset of pages

Open your current scanning project in Adobe Scan. Instead of selecting all 160+ pages, select the first 50 to 80 pages.

Save the first batch

Tap the 'Save PDF' button to export this selected batch as a standalone PDF document.

Save the remaining pages

Go back into the scan project, select the next batch of pages, and save them as a second PDF. Repeat this process until all pages are saved.

Combine the PDFs later

Use a desktop or mobile PDF merger tool to combine these smaller PDF files into one final, large document.

Save the Scan as Multiple Smaller Documents

Safe Data Practice: Saving in batches prevents complete data loss if the app crashes while trying to process hundreds of high-resolution images at once.

Solution 2

Update Adobe Scan and iOS Version

Updating your software can resolve known memory bugs or background processing errors causing the save failure.
