About this tool
Spot blank pages (common in double-sided scans) and duplicated pages, review them as thumbnails, and download the PDF without them.
Each page is rendered small: it counts as blank when ink covers less than your threshold and it has no text; duplicates are found with a visual fingerprint (difference hash) combined with the page text.
Example: a 40-page duplex scan with 9 blank backs → a 31-page PDF.
Nothing is removed without your review — click a thumbnail to keep or drop it. The new PDF is checked for the right page count before download.
