Remove Cloudy Background Image Behind All Pages of a PDF in One Fell Swoop

[Blaineoreski]

Here is an old document that has been scanned and shared online. The pages have faded.

The text is still valuable, but the page color gets in the way.


Seems that in the scan the page color we see is defined apart from the text, existing as a background image.


Although there's some risk to doing this in terms of what could be lost from the document, it is minimal for my purposes.

Trouble is, there's over a hundred pages, and for some files a couple of hundred.

For the PDF tool I'm using now - PDF X-Change Editor - there's no bulk method of deleting the background image. I've got to do them one page at a time.

Is there any PDF tool that you all know of that could remove that background image from every page in one go? Something that will actually DELETE the image. I've seen some ideas that use image processing software to try and wash out the color. Hoping there's some way to actually bulk-delete the images.

Of course the linked file is quite short. I could manually delete the images in no time. Challenge is, there's a BUNCH of books like this I need to work - topping out well over several hundred pages.

Is there any automated way you can see to delete these background images?


Sincerely,

Blaine
