Remove Blank Pages - Free Online Browser Tool

Detect and delete pages that are blank or near-blank, with an adjustable tolerance.

Blank pages get into a document in ways nobody notices: a duplex scan that captures the back of a sheet, a merge that picked up an empty appendix, a cover sheet that was never filled in. This measures how much ink is actually on each page and drops the ones that fall below a tolerance you choose.

This remove blank pages utility runs completely inside your web browser.

How to Use the Remove Blank Pages Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load the document

    Works on any PDF, including ones with a mix of scanned and digital pages.

  2. Set the tolerance

    Strict catches only pure white. Normal also catches faint scanner edges, which is what you want for a real scan.

  3. Process and detect

    Each page is rendered small and measured by dark-pixel coverage, which is far more reliable than judging by file size.

  4. Review the report

    You get the cleaned PDF and a list of exactly which page numbers were removed.

Frequently Asked Questions

Could this remove a page that has content on it?

Not one with meaningful ink on it. A page with a faint pencil note, a single line of text or a small signature still exceeds even the strict tolerance. The report tells you exactly what went, so check it rather than trusting the count.

Why are several blank pages found in a row?

That is normal in a duplex scan, where the back of a sheet often produces a near-blank page. If your document was meant to have those as deliberate dividers, skip removal.

Will removing them make the file smaller?

Often noticeably. Blank scanned pages still carry full-resolution image data, which is often the heaviest thing in the file despite showing nothing.

What tolerance should I use for a scan?

Normal. Strict will leave behind the grey scanner edge you get from most flatbeds, which is exactly the kind of page this is meant to catch.

Are the removed pages recoverable afterwards?

From this output, no. Check the report before you use the cleaned file, and keep the original until you are satisfied.
