I am looking for an application or an online service that could basically apply the above mentioned filter or something like to to an existing PDF file ( I do not have the images ) so the document that i have looks like [this](https://drive.google.com/file/d/1fjCM7aA59N-kOxWsUd-9d68ZonKtNos0/view?usp=sharing) and i want it to be converted to something like [this later.](https://drive.google.com/file/d/1HGa9naWMwV8t71truCkLPKmrIw686S3k/view?usp=sharing)

PS : I did try to find a service an app or a site that can do this for me, but could not find one I know I could do it using Open CV or some other library but i don’t want to code something that long just for this, any and all abstraction and help would be greatly appreciated

if you have an android device then use [adobe scan](https://play.google.com/store/apps/details?id=com.adobe.scan.android&hl=en_IN)

idk whether u can import pdf in it probably it will. If not convert the pdf to image using [pdf utils](https://play.google.com/store/apps/details?id=pdf.shash.com.pdfutility&hl=en_IN)

then select those images(in adobe scan app) tap colour option choose whichever colour u want save it

thats it
