Images are commonly used to represent important information in Word documents. The inclusion of images alongside text makes the content more appealing. In certain cases, you may need to extract the images embedded within the Word documents programmatically. To achieve that, this article covers how to extract images from Word documents using Java.

The images in a Word document are represented using shape objects. Therefore, to retrieve images, you will have to process every shape in the document. The following are the steps to extract images from a Word DOCX document in Java.
- First, load the Word file using Document class.
- Then, get all the shapes into an NodeCollection<Shape> object using Document.getChildNodes(NodeType.SHAPE, Boolean) method.
- Loop through the retreieved shapes.
- In each iteration, check if the shape has an image using Shape.hasImage() method.
- Finaly, extract the image and save it using Shape.getImageData().save(string) method.
The following code sample shows how to extract images from a DOCX document in Java.
