Put content of a pdf with many pages without converting into text file into a office 365 word document

I’m writing a document in office word. Then I have to put in the document the content of the PDF file with some pages. This should happen without converting the PDF file into a text file. I found a way that this way is too complicated. In this way, I have to convert with a PDF program, the PDF into for instance a tif file and than put the tifs into the document. I seek for a most easy way instead.
