Clean Blank Pages in Scans
High-speed duplex scanners feed every sheet double-sided, creating hundreds of useless blank pages in your PDF files. Worse, faint punch holes, staple marks, paper translucency, or scanner dust fool naive tools into keeping empty pages or deleting pages with faint print.
Employs intelligent computer vision density analysis to detect genuine blank pages while distinguishing them from scanner noise, paper fiber textures, and punch holes. The algorithm guarantees 100% protection for any page containing readable text, handwriting, barcodes, or stamps. Cleans thousands of pages in seconds, dramatically reducing file size and page count.
Adjust the scanner sensitivity slider to see real-time blank page identification and text protection:
- 1Set the scanner noise threshold (Low, Medium Balanced, or High for dark textures).
- 2Enable Punch Hole & Margin Ignore to filter out binder hole shadows and scanner bed borders.
- 3Ensure Strict Text Protection is active to prevent any page with text or barcodes from being deleted.
- 4Select your batch of multi-page scanned PDFs or duplex feeds.
- 5Execute the clean-up — empty reverse pages are removed cleanly while critical pages remain intact.
You can fine-tune the pixel density threshold (e.g. 99.2% white or 98.5% with bleed-through tolerance) so minor punch-holes and shadow margins are never mistaken for content.
DocInspector performs pure structural page tree trimming without re-compressing existing pages, keeping your original text and images at 100% native quality.
The audit log lists every removed page number and original file name, with an option to isolate removed pages into a separate backup directory.
