There’s absolutely no guarantee that any PDF can be converted to a Word file. The PostScript language and the PDF technology can contain and display so much more than the Word engine can understand and recreate… It’s like trying to let a dog sing exactly like Pavarotti. I’d rather state that it takes sheer luck and smart insights, if you pick a not too complex PDF file with a very textual appearance, layout, and structure to be converted into a proper and similar Word document.
There is no way to make a PDF that is the exact and similar text of a Word file… There’s no way, that can be done. Some PDF files are so much bigger and complex, that even the best PDF conversion software cannot understand the text. For example… The word and document name are different. A PDF file can have multiple text levels, with different colors and font styles. There’s no easy way, how to translate them to another Word document. In some PDF files, there are multiple document names, or with names that are not the exact same words. PDF files must have well-defined titles and descriptions. For example, the word and title are different or do not contain much information, but it is very common. The PDF files will typically be very long, and contains a lot of lines of text. There’s a lot to go through, if you want to see.
