I am unable to download papers I really need for my research. Does anyone have any tips on how to fix it? A blank screen of the paper opens up but I cannot see the text. D: Are there any alternative website?

I found the content that I want however it's in PDF format and actually they put each page as a page screenshot not as text. It's scanned copy. In case if anyone can assist me about converting this to EPUB please help me in advance. Or idk from another source etc. but ig requesting is not allowed (idk if that counts as a request?)
