What if it removes a page I wanted?

Lower the sensitivity and run it again. Your original file is never modified.

Why does it warn about some pages?

Those pages were close to the threshold, so the judgement was less certain.

Will it remove every page?

No. If everything looks blank the tool stops and asks you to lower the sensitivity.

Remove Blank Pages

Take the empty pages out of a scanned document.

How it works

Blank pages are detected by measuring ink coverage, then removed. Pages that were only marginally below the threshold are listed as uncertain in the result, because a page with very faint handwriting can look blank to a pixel counter. Check the output before discarding your original.
