Convert Word to Image | WinUI Word Library

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.

Platform independent

Word Library is a non-UI library for automating conversion of Word documents to images in .NET Framework, .NET Core, Blazor, Xamarin, and .NET MAUI applications.

Word-to-image options

Specific pages

Convert the entire document to images

c#
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

c#
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

c#
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");
