Images added to a Microsoft Word document are not intended to be extracted, but if you need to, you can extract them. DOCX (the default file extension of Microsoft Word) is actually an archive file format, which can be extracted using an appropriate tool. There are at least two ways to extract images from a document in Microsoft Word.
1. Extract images from a DOCX file by saving the document as a web page
The first method you can use to extract images from a DOCX file is by saving it as a web page. In this method, the text file of the document will be saved in an HTML format, while the images are saved in a separated folder. This method is no different from saving a regular web page from the internet.
First off, open the DOCX file you want to extract the images from using Microsoft Word, go to the File menu and select Save As.

Select a folder you want to save the document to. Before clicking the Save button, specify the file format and make sure to select Web Page.

Go to the folder where the document is saved and you should see an HTML file a well as a folder. The images of your DOCX file are saved to this folder.

2. Extract images from a DOCX file using an unzipper tool
As mentioned, a DOCX file is actually an archive format. If you extract a DOCX file, you will find an XML file as well as three folders. However, not all unzipper tools might support DOCX format. PeaZip is one of the unzipper tools that support DOCX format. This tool is free and available for Linux and Windows.
To extract a DOCX file using PeaZip, right-click the DOCX file you want to extract and select PeaZip -> Extract Here.

Wait a moment until PeaZip is done extracting your DOCX file. Once done, you can go to the word\media folder generated by the extraction process to find the images of your document.
