Output in word is a non editable image

If you make a "full conversion" of your PDF and the generated Word document only contains images,
It means that your PDF only contains images, no words or other structures.

Solution:

Use OCR text recognition. It will recognize the text inside the pictures, but graphics will get lost.
It will take a lot of efforts to reassemble the PDF in a editable word document.

The best option is to make a OCR conversion to get the editable text.
And do another conversion to get the pictures. But it will take some efforts to place things in the right position.
Put the text in the places you desire. And alter the pictures to remove the text.
