unabale to convert the .pdf files to .doc for the scanned docs

I am unable to convert the .pdf files to .doc for the scanned documents.

How do I convert the documents to word format which are scanned by a scanner.
Is there any way??
=======================
If your PDF file was created from scanner, we suggest you may download mini PDF to
Word OCR Converter from our partner's website to try,

please select "8. OCR PDF file (Language: English)" option in mini PDF to
Word OCR Converter, then you can convert your scanned PDF file to editable
word document properly.
