Remover Páginas em Branco

Each page is rendered at reduced size and the tool counts pixels that are noticeably darker than white. If that share is below the limit set by the sensitivity slider, the page is flagged, so pages with faint scanner noise can still count as blank.

It sets how much ink a page may contain and still count as blank. At 100% only pages with under 0.1% non-white pixels are flagged, at 0% pages with up to 5% are, and the default 80% sits at about 1%.

Lower the sensitivity if pages that look empty were missed, and raise it if pages with a light header, footer, or watermark were flagged. Then click Detect Blank Pages again and check the thumbnails.

After detection the tool shows a thumbnail of every flagged page, and clicking a thumbnail deselects it so it stays in the document. Only the pages that remain selected are removed when you confirm.

A lone page number covers well under 0.1% of the page, so even the strictest setting can flag it as blank. That's why the thumbnail review matters when such pages need to stay.

The kept pages are copied over exactly, with their content, fonts, and order untouched. Bookmarks aren't carried into the new file, since the pages are assembled into a fresh PDF, so rebuild them with Edit Bookmarks if you need them.

Every page has to be rendered to pixels before it can be measured, so the time grows with page count and page complexity. Progress is shown while it works, and nothing else is needed from you until the thumbnails appear.

No. Pages are rendered and analyzed in your browser, and the cleaned PDF is written locally. That's also why the scan speed depends on your own device rather than a server.
