What does sensitivity measure?

It is the maximum sampled ink percentage allowed for a page to be considered blank.

Can faint text be removed accidentally?

Yes. Light content can fall below the threshold, so review the detected page numbers.

Are kept pages recompressed?

No. They are copied from the source PDF.

What if every page is detected as blank?

The tool blocks removal and asks for a lower sensitivity.

Does it show page thumbnails?

It reports page numbers rather than a full per-page visual gallery.

About the Remove Blank PDF Pages

Remove Blank PDF Pages renders a lightweight version of every page and samples non-white pixels to estimate ink coverage. Pages at or below the chosen threshold are classified as blank.

The result lists detected-blank and kept page numbers before removal. Raising the threshold is more aggressive and can classify faint writing, stamps, or light scan content as blank.

Only kept source pages are copied into the result, so their original PDF quality is retained. Detection itself can take time on long scans because every page must be rendered locally.
