Let’s learn how to convert a Word document to a PDF programmatically in C# without Microsoft Office or interop.
Syncfusion Word library (Essential DocIO) renders the contents of a Word document page by page and adds the contents of each page to the PDF document using Syncfusion PDF library. This converter can be easily integrated into .NET Framework (WinForms, WPF, ASP.NET Web forms, and ASP.NET MVC), ASP.NET Core, and Xamarin applications. It works well on both full trust and partial trust environments such as Azure applications.
This converter offers several options to customize Word to PDF conversion,
- Embed complete or subset font information for TrueType fonts.
- Substitute alternate fonts from the device or upload the original fonts.
- PDF conformance level PDF/A1B or PDF/X-1a:2001.
- Convert accessible Word document (508 compliance) to Accessible or Tagged PDF
- Export the headings or bookmarks in the Word document as PDF bookmarks.
- Export the Word form fields as PDF form fields during Word to PDF conversion.
- Adjust JPEG image quality and resolution for optimizing the converted PDF file size.
This converter supports all the elements of a typical Word document like text, formatting, images, tables, hyperlinks, fields, bookmarks, table of contents, shapes, headers, footers, etc. Refer our documentation to know more about Word to PDF conversion.
1.Create a new C# console application (.NET Framework) project.
2.Install DocToPDFConverter.WinForms NuGet package as a reference to your applications from the NuGet.org. This package contains Syncfusion libraries to perform Word to PDF conversion without Microsoft Office or interop.
3.Include the following namespace in the Program.cs file. The following code snippet is used to open the Word document with DocIO.
using Syncfusion.DocIO; using Syncfusion.DocIO.DLS; using Syncfusion.DocToPDFConverter; using Syncfusion.Pdf;
4.Use the following code snippet to create Word file with simple text.
//Get the path of existing Word document string fullpath = @"...\..\DocToPDF.docx"; //Loads an existing Word document WordDocument wordDocument = new WordDocument(fullpath, FormatType.Docx); //Creates an instance of the DocToPDFConverter DocToPDFConverter converter = new DocToPDFConverter(); //Converts Word document into PDF document PdfDocument pdfDocument = converter.ConvertToPDF(wordDocument); //Releases all resources used by DocToPDFConverter converter.Dispose(); //Closes the instance of document objects wordDocument.Close(); //Saves the PDF file pdfDocument.Save("DocToPDF.pdf"); //Closes the instance of document objects pdfDocument.Close(true);
The following screenshot illustrates the input Word document.
The next screenshot shows the final PDF document converted from the Word document.
