Note: PDFs that are complex, have different styles, fonts etc, include text boxes, lines/shapes and tables may not convert as required.
It should also be noted that not all PDFs are created and saved/printed the same way.
There are different types of PDF and if the PDF has been saved/printed as a PDF Image, then the characteristics of that PDF will resemble those of a Jpeg/Jpg image with no edible/copyable text.



Personally, I have never come across a PDF that couldn’t be edited, one way or another, but when you have to open PDFs in image editors to do the editing, it becomes very time consuming indeed.
You will have to try to see the outcome of your converted file(s) to see if it is usable.
