Multiple PDFs Image Data Extraction

Hi team!
I have some pdfs, all contain images in it. I want to extract the data from these images. I used Get OCR Text, Find Image, Click OCR Text, and different OCR engines like Teserract OCR, Google OCR, etc. But since I have multiple pdfs, so they fail on processing all these. Also I want to extract specific data from pdf based on some specific conditions. Mostly the errors I got are: Activity timeout exceeded, Scrape returned empty text, etc. Please help me with the clues or hints so that I can approach to the correct solution.

Thanks team!
