Overview

The Syncfusion WinUI Word Library (DocIO) offers powerful and comprehensive APIs to convert a Word document into an image programmatically with a few lines of code without Microsoft Word or interop dependencies. It allows you to generate an entire document as images or a single page of a Word document as an image to provide the document’s preview, thumbnail, or to print it.


Key features

Fast and reliable

Convert complex Word documents into image files faster in a batch process, compared to Office automation libraries.

Partial trust environment

Convert Word documents to image files in partial trust environments like Azure and AWS.

Convert the entire document to images

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

//Load file stream into Word document.
using WordDocument wordDocument = new(wordDocumentStream, FormatType.Automatic);
//Create a new instance of DocIORenderer class.
using DocIORenderer render = new();
//Convert the entire Word document to images.
Stream[] imageStreams = wordDocument.RenderAsImages();
//Save the memory stream as file.
for (int i = 0; i < imageStreams.Length; i++)
    Save(imageStreams[i] as MemoryStream, "WordToImage_" + i + ".jpeg");

Convert first page of document to image

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

using WordDocument wordDocument = new(wordDocumentStream, FormatType.Automatic);
using DocIORenderer render = new();
//Convert the first page of the Word document into an image.
Stream imageStream = wordDocument.RenderAsImages(0, ExportImageFormat.Jpeg); 
Save(imageStream as MemoryStream, "WordToImage.jpeg");

Convert a specific range of pages to images

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

using WordDocument wordDocument = new(wordDocumentStream, FormatType.Automatic);
using DocIORenderer render = new();
//Convert a specific range of pages in Word document to images.
Stream[] imageStreams = wordDocument.RenderAsImages(1, 2); 
for (int i = 0; i < imageStreams.Length; i++)
    Save(imageStreams[i] as MemoryStream, "WordToImage_" + i + ".jpeg");
