Overview

The Syncfusion Blazor 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

A non-UI component to automate conversion of Word documents to images in .NET Framework, .NET Core, Blazor, Xamarin, and .NET MAUI applications.


Word-to-image options

Specific pages

Convert a specific page in a Word document into an image.

Specific range of pages

Convert a specified range of pages in a Word document into images.

Font substitution

The built-in font substitution event allows users to choose alternate fonts from the device or upload fonts with a few lines of code.


Convert an entire document to images

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

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

Convert first page of document to image

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

using (WordDocument wordDocument = new WordDocument(wordDocumentStream, FormatType.Automatic))
{
    using (DocIORenderer render = new DocIORenderer())
    {
        //Convert the first page of the Word document into an image.
        Stream imageStream = wordDocument.RenderAsImages(0, ExportImageFormat.Jpeg); 
        using (FileStream fileStreamOutput = File.Create("WordToImage.jpeg"))
            imageStream.CopyTo(fileStreamOutput);
    }
}

Convert a specific range of pages to images

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

using (WordDocument wordDocument = new WordDocument(wordDocumentStream, FormatType.Automatic))
{
    using (DocIORenderer render = new DocIORenderer())
    {
        //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++)
        {
            using (FileStream fileStreamOutput = File.Create("WordToImage_" + i + ".jpeg"))
                imageStreams[i].CopyTo(fileStreamOutput);
        }
    }
}
