Remove Blank Pages looks at every page of your PDF, measures how much of it has ink on it, and marks the empty ones for removal. Scanned blank pages with a few specks or an edge shadow still count as blank. You see every page before anything is deleted, and the work runs in this browser tab with pdf.js and pdf-lib; the file is never uploaded.
How to use it
- Choose a PDF or drop it here.
- Wait while each page is checked. Pages that look blank are outlined and marked Remove.
- Tap any page to switch it between Keep and Remove. Move the sensitivity slider if too many or too few pages were caught.
- Click "Remove pages & download".
Frequently asked questions
Is my PDF uploaded?
No. Pages are rendered with pdf.js and the new PDF is built with pdf-lib, both in your browser. The file stays on your device.
How does it decide a page is blank?
It renders each page small, ignores near-white pixels, a thin strip around the edges and isolated specks, then measures what share of the page is left. Pages under the sensitivity threshold are marked blank. It is a guess, which is why you can check and change every page.
A page with only a page number was kept. Why?
A page number is real ink. Raise the sensitivity to catch pages with a few small marks, or tap the page to mark it yourself.
Does removing pages lower the quality of the rest?
No. The pages you keep are copied as they are, not re-rendered or recompressed.
What about very faint pencil or light gray text?
Very light marks can look like paper to the detector. Lower the sensitivity, and look over the pages marked Remove before you download.
