One file. It stays on your device.
Duplex scanners produce blank pages by the dozen. Anything printed on one side goes through the feeder as two pages, and half of them are the backs. On a fifty page batch that is twenty five pages of nothing.
Everything happens inside this page. Your file is read by JavaScript running on your own machine, and no part of it is sent anywhere.
Why blank pages are hard to find
A page from a word processor with nothing on it has an empty content stream, and finding those is easy. A scanned blank page is the opposite: it is a photograph of a sheet of paper, and photographs of paper are full of grey speckle, dust, the shadow of the scanner lid and often a faint impression of what is printed on the other side.
By the only measure a computer has, that page is covered in content. So looking at the file structure does not work, and this tool draws each page and looks at the result instead.
How the decision is made
Every page is rendered at 60 dots per inch, which is small and quick and still leaves a page of text with thousands of dark pixels. A sample of the pixels is checked, and a page is called blank when almost none of them are darker than near-white.
Speckle is scattered and thin. Content is dense and dark. That difference is what the threshold separates, and it is why sampling every eighth pixel is enough rather than a shortcut.
The sensitivity setting
Strict treats a page as blank only when it is almost perfectly clean. This is the safe setting and the one to use when losing a page would matter.
Relaxed tolerates more marking, which catches pages with a stray scanner line, a punch hole shadow or bleed-through from the other side. It is the right choice on an old or poor quality scan, and it carries a real risk of removing a page that had one faint line of handwriting on it.
Check before you commit
The pages the tool believes are blank are shown to you first, marked in the grid, and you can unmark any of them. Nothing is removed until you press the button.
That step exists because the alternative is a tool that quietly deletes a page you needed, and you find out weeks later.

Questions about Remove Blank Pages
How do I remove blank pages from a scanned PDF?
Add the file and the tool draws every page and checks it for content. The pages it thinks are blank are marked in the grid for you to confirm before anything is removed.
Why does it not just look for empty pages in the file?
Because a scanned blank page is a photograph of paper, full of speckle and shadow. By the file's own measure it is covered in content, so it has to be looked at rather than inspected.
Could it remove a page I wanted?
Not without you agreeing. Every page it flags is shown marked in the grid and you can unmark any of them before pressing the button.
What if it misses some blank pages?
Switch to the relaxed setting, which tolerates speckle, punch hole shadows and bleed-through from the other side of the sheet.
