Since Microsoft Word 2010, the Screenshot feature has been added under Insert tab to take screenshot of opening windows and insert in the document. And here, I will guide you to save one page of a Word document as image with this feature.

1. Open the Word document, show the specified page you will save as image in the screen, and then change zoom level by clicking View > One Page. See screenshot:

Note: If you need to save multiple pages as one image, you can click View > Multiple Pages to show these pages in your screen together.

2. In the Word window, click File > New (press Ctrl + N keys) to create a new document.

3. In the new document, click Insert > Screenshot, and then select screenshot of the document you will save as image from the drop-down list. See screenshot:
 
Note: You can also click Insert > Screenshot > Screen Clipping, and draw the scope you will save as image.

Now the screenshot of the specified document is inserted in the new document.

4. Right click the inserted screenshot, and select Save as Picture from the context menu. See screenshot:

5. In the popping out File Save dialog box, please (1) open the destination folder you will save the image in, (2) name the image in the File name box, (3) specify the image type from the Save as type drop down list, and finally (4) click the Save button. See screenshot:

So far, the specified page of certain Word document has been saved as one image already.

Note: This method does not work in Word 2007 or earlier version because they don’t support the Screenshot feature.

Fantastically batch save each page of the specified Word document as individual image, with only several clicks! Kutools for Word released this magic Export Doc as Images feature, which will save your time, and make your work much easier on saving Word documents as images!
