FAQ

Can I detect blank pages without deleting them?

Yes. This tool only analyzes the PDF and creates a text report; it does not modify the source document.

Does a page number count as visible content?

Usually yes. Rendered page numbers create dark pixels and prevent the page from being classified as blank at normal sensitivity.

Can the detector find blank pages in scanned PDFs?

Yes. It analyzes rendered pixels, so it works with scans as well as digitally generated PDFs.

Why is a nearly empty page marked as blank?

The chosen threshold may be too permissive. Select a stricter sensitivity and run the scan again.

Is the PDF uploaded during blank-page detection?

No. PDF.js reads and renders the file locally in your browser.
