Syncfusion Essential DocIO is a .NET Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can extract the images from Word document and save the extracted images to the desired location in C# and VB.NET.

Image is one kind of document objects which belongs to paragraph items, and we can extract the images by iterating through the paragraph items.

//Loads the template document
WordDocument document = new WordDocument("Template.docx");
int index = 0;
//Visits all document entities.
foreach (var item in document.Visit())
      switch (item.EntityType)
         // Gets the list of pictures in the Word document and save as Image
         case EntityType.Picture:
              WPicture picture = item as WPicture;
              string imageName = String.Format(@"Images/Image-{0}.jpeg", index);
              picture.Image.Save(imageName, System.Drawing.Imaging.ImageFormat.Jpeg);
//Closes the document


'Loads the template document
Dim document As WordDocument = New WordDocument("Template.docx")
Dim index As Integer = 0
'Visits all document entities.
For Each item In document.Visit()
    Select Case item.EntityType
         'Gets the list of pictures in the Word document and save as Image
         Case EntityType.Picture
              Dim picture As WPicture = TryCast(item, WPicture)
              Dim imageName As String = String.Format("../../Images/Image-{0}.jpeg", index)
              picture.Image.Save(imageName, System.Drawing.Imaging.ImageFormat.Jpeg)
              index += 1
     End Select
  1. Helper Class


public static class DocIOExtensions
    public static IEnumerable<IEntity> Visit(this ICompositeEntity entity)
        var entities = new Stack<IEntity>(new IEntity[] { entity });
        while (entities.Count > 0)
            var e = entities.Pop();
            yield return e;
            if (e is ICompositeEntity)
                foreach (IEntity childEntity in ((ICompositeEntity)e).ChildEntities)



Public Module DocIOExtensions
Public Iterator Function Visit(ByVal entity As ICompositeEntity) As IEnumerable(Of IEntity)
    Dim entities = New Stack(Of IEntity)(New IEntity() {entity})
    While entities.Count > 0
        Dim e = entities.Pop()
        Yield e
        If TypeOf e Is ICompositeEntity Then
            For Each childEntity As IEntity In CType(e, ICompositeEntity).ChildEntities
