How to remove the blank pages from a PDF
When you scan double-sided, the empty backs end up in the PDF. The tool measures how much ink each page has (ignoring the edges, where scanner shadows usually appear) and marks as blank the pages below the threshold.
Select or drag the scanned PDF.
Review the thumbnails: the ones with a cross will be removed. Tap any of them to change it or adjust the ink threshold.
Press Remove blank pages and download the clean PDF.
