{
    //Initialize the ChartToImageConverter for converting charts.
    wordDocument.ChartToImageConverter = new ChartToImageConverter();
    //Convert the entire Word document to images.
    Image[] images = wordDocument.RenderAsImages(ImageType.Bitmap);
    //Save the image as jpeg.
    for (int i = 0; i < images.Length; i++)
        images[i].Save("WordToImage_" + i + ".jpeg", ImageFormat.Jpeg);
}

Convert first page of document to an image

c#
using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.OfficeChartToImageConverter;

using(WordDocument wordDocument = new WordDocument("Template.docx", FormatType.Docx))
{
    wordDocument.ChartToImageConverter = new ChartToImageConverter();
    //Convert the first page of the Word document into an image.
    Image image = wordDocument.RenderAsImages(0, ImageType.Bitmap);
    image.Save("WordToImage.jpeg", ImageFormat.Jpeg);
}

    //Convert a specific range of pages in Word document to images.
    Image[] images = wordDocument.RenderAsImages(1, 2, ImageType.Bitmap);
    for (int i = 0; i < images.Length; i++)
        images[i].Save("WordToImage_" + i + ".jpeg", ImageFormat.Jpeg);
