Easy way to tell, when you open the PDF, can you successfully search for
text.


Not always. There are text PDFs, and raster image PDFs. The raster image
PDFs cannot be searched (well, maybe they can since OCR is getting better).

But PDFs can be created with plain text in view, but also compressed and/or
encrypted where you can see or read the text just using a text editor.
Which is why if you have non-image PDFs and want to compare, look into a
PDF kit already available. They're really powerful and will do the heavy
lifting.


Not always what?

My point being if you can successfully search for text in a PDF inside
Acrobat, then there's embedded text rather than images; doesn't matter if
the text is plain, compressed, or encrypted.

Thus the PDF kit's you suggest (or others) should be able to extract it.
