A professional PDF to Word conversion tool is needed since you need to convert PDF to DOC for better editing PDF content. Here I recommend you to use MicroPDF PDF to DOC Converter!
This converter is able to convert native and encrypted PDF to DOCX/ DOC with unchanged original pages, images, hyperlinks and bookmarks, etc. The new OCR can recognize the image-base PDF in 17 languages. As a standalone program, it does not depend on any other program such as Adobe Acrobat, Acrobat Reader or Microsoft Word. You can select batch conversion and partial conversion as you like.
