How does it decide a page is blank?

Each page is rendered and its pixels measured. If the share of non-paper pixels falls below your sensitivity setting, the page counts as blank.

Will it delete pages that only have a page number?

It might at a high sensitivity. Lower the slider until those pages are kept.

No. Kept pages are copied across untouched — same text, images and quality.

Yes. The threshold is deliberately tolerant rather than requiring pure white.

Find and drop empty pages left by scanners and duplex printing.
