How does blank page detection work?

The tool analyzes each page for text content, images, and graphical elements. Pages with no detectable content (or content below the sensitivity threshold) are flagged as blank. You can review flagged pages before removing them.

Will it remove pages with just a header or footer?

Pages containing only headers, footers, or page numbers can be handled by adjusting the sensitivity threshold. At low sensitivity, only completely blank pages are removed. At higher sensitivity, pages with minimal content (like just a page number) are also flagged.

Can I review before pages are removed?

Yes. The tool shows you which pages it detected as blank. You can uncheck specific pages to keep them (for example, intentional separator pages) before applying the removal.

Will this reduce the file size?

Yes. Removing pages reduces the file size. The reduction depends on how many blank pages are present and whether they contained any embedded content (some 'blank' pages actually contain hidden elements).
