Step-by-Step Guide to Extracting Images from a Word Document in C#

In Word documents, images are represented as shapes. To extract images from protected Word documents or standard DOCX files, you need to process all the shapes within the document. Here’s how to programmatically extract images from Word documents in C#:

  1. Load the Word file using the Document class.
  2. Retrieve all shapes containing images into an IEnumerable<Shape> object using the Document.GetChildNodes(NodeType.Shape, Boolean) method.
  3. Loop through the retrieved shapes.
  4. For each shape, extract the image and save it using the Shape.ImageData.Save(string) method.

Here’s a practical code sample demonstrating how to extract images from a Word document in C#:

// Load the document
Document doc = new Document("input.docx");

// Get all shapes that contain images
NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);

// Extract and save each image
foreach (Shape shape in shapes)
{
    if (shape.ImageData.HasImage)
    {
        // Extract image file path
        string imagePath = $"Image_{shape.Name}.png";
        shape.ImageData.Save(imagePath);
    }
}
