Syncfusion DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can convert a Word document to image in Windows Forms.

Steps to convert Word document to Image in Windows Forms

Step 1: Create a new Windows Forms application project.

Step 2: Install Syncfusion.DocIO.WinForms NuGet package as a reference to your Windows Forms application from the NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your application to use our components.

Step 3: Include the following namespaces in the Form1.Designer.cs file.

C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;

Step 4: Add a new button in Form1.Designer.cs to create Word file as follows.

C#

private Button btnCreate;
private Label label;

private void InitializeComponent()
{
    this.label = new System.Windows.Forms.Label();
    this.btnCreate = new System.Windows.Forms.Button();
    this.SuspendLayout();

    // label
    this.label.Location = new System.Drawing.Point(0, 40);
    this.label.Name = "label";
    this.label.Size = new System.Drawing.Size(426, 35);
    this.label.TabIndex = 0;
    this.label.Text = "Click the button to Convert Word document to image generated by Essential DocIO";
    this.label.TextAlign = System.Drawing.ContentAlignment.MiddleCenter;

    // btnCreate 
    this.btnCreate.Location = new System.Drawing.Point(90, 110);
    this.btnCreate.Name = "btnCreate";
    this.btnCreate.Size = new System.Drawing.Size(223, 36);
    this.btnCreate.TabIndex = 1;
    this.btnCreate.Text = "Convert Word to Image";
    this.btnCreate.Click += new System.EventHandler(this.btnConvert_Click);
       
    // Form1        
    this.ClientSize = new System.Drawing.Size(450, 150);
    this.Controls.Add(this.label);
    this.Controls.Add(this.btnCreate);
    this.Name = "Form1";
    this.Text = "Convert Word document to Image";
    this.ResumeLayout(false);
}

Step 5: Add the following code in btnConvert_Click to convert Word document to image with simple text.

C#

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