Remove blank pages from PDF

Duplex scanning is the most common source of blank pages: the scanner captures both sides of every sheet, so every one-sided page leaves an empty back in the PDF. A 30-page letter can easily turn into a 60-page scan, half of it white.

This tool renders each page, measures how much of it is actually printed, and flags the pages that are empty. A thin band along the edges is ignored, so scanner shadows and feed marks do not count as content, and small specks of dust are tolerated.

Exported documents pick up blank pages too: a stray page break or an empty paragraph at the end of a Word file often becomes an empty last page in the PDF, and section breaks can add blank pages in the middle.

The tool catches those as well - including pages that are empty apart from a page number in the header or footer, which Word adds to every page. Pages with any real words on them are always kept.

Detection is automatic, but not infallible. On scanned pages, which have no text layer, very faint content - a light pencil note, a pale stamp, or a few handwritten words - may be marked as blank. That is why every page is shown as a thumbnail and nothing is deleted until you click the button.

If too many or too few pages are marked, change what counts as blank: "Only empty pages" is the most careful setting, while "Ignore specks & noise" also catches noisy scans and show-through from the other side of the sheet.

Scanned documents are often personal: bank statements, medical letters, signed contracts. Everything here runs in your browser, so the PDF is never uploaded, stored, or seen by anyone else.
