2. Install Syncfusion.DocToPDFConverter.WinForms and Syncfusion.OfficeChartToImageConverter.WPF NuGet packages as a reference to your .NET Framework applications from the NuGet.org.

3. Include the following namespace in the Program.cs file.
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO;
using Syncfusion.Compression.Zip;
using Syncfusion.OfficeChart;
using Syncfusion.OfficeChartToImageConverter;
using System.IO.Compression;
using ZipArchive = Syncfusion.Compression.Zip.ZipArchive;

4. Use the following code to convert Word document to images and download as zip.
   C#

// Load an existing Word document from the specified path.
using (WordDocument wordDocument = new WordDocument(Path.GetFullPath(@"../../Data/Template.docx"), FormatType.Docx))
{
   // Initialize the ChartToImageConverter for converting charts during Word to image conversion.
   wordDocument.ChartToImageConverter = new ChartToImageConverter();
   // Set the scaling mode for charts (Normal mode reduces the file size).
   wordDocument.ChartToImageConverter.ScalingMode = ScalingMode.Normal;
   // Convert the entire Word document to images.
   Image[] images = wordDocument.RenderAsImages(ImageType.Bitmap);
   // Initialize a ZipArchive to store the converted images.
   using (ZipArchive zipArchive = new ZipArchive())
   {
       // Set the compression level to the fastest.
       zipArchive.DefaultCompressionLevel = (Syncfusion.Compression.CompressionLevel)CompressionLevel.Fastest;
       int i = 0; // Initialize an index for naming the images.
       foreach (Image image in images)
       {
           // Create a memory stream to hold the image data.
           MemoryStream imageStream = new MemoryStream();
           // Save the image to the memory stream in JPEG format.
           image.Save(imageStream, ImageFormat.Jpeg);
           imageStream.Position = 0;
           // Create a ZipArchiveItem with the image stream.
           string imageName = $"WordToImage_{i}.jpeg";
           ZipArchiveItem item = new ZipArchiveItem(zipArchive, imageName, imageStream, true, FileAttributes.Normal);
           zipArchive.AddItem(item);
           i++; // Increment the index for the next image.
       }
       // Save the ZipArchive to a memory stream.
       using (MemoryStream zipStream = new MemoryStream())
       {
           zipArchive.Save(zipStream, false);
           zipStream.Position = 0;
           // Write the zipStream to a file.
           File.WriteAllBytes(Path.GetFullPath(@"../../Data/Images.zip"), zipStream.ToArray());
       }
   }
}
