ODT files are OpenDocument Text files created with word processing programs such as free OpenOffice Writer. Like DOCX files, ODT files can contain content like text, images, objects and styles, but they may not be readable by some people who don't have the appropriate application installed. If you plan to share an ODT file, it's best to convert it to pdf so everyone can access it. In this article, we will explain how to convert ODT to PDF in C# and VB.NET using Spire.Doc for .NET.

Install Spire.Doc for .NET

To begin with, you need to add the DLL files included in the Spire.Doc for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

PM> Install-Package Spire.Doc

Convert ODT to PDF using C# and VB.NET

The following are the steps to convert an ODT file to PDF:

• Create an instance of Document class.
• Load an ODT file using Document.LoadFromFile() method.
• Convert the ODT file to PDF using Document.SaveToFile(string fileName, FileFormat fileFormat) method.

using Spire.Doc;

namespace ConvertOdtToPdf
{
    internal class Program
    {
        static void Main(string[] args)
        {
            //Create a Document instance
            Document doc = new Document();
            //Load an ODT file
            doc.LoadFromFile("Sample.odt");

            //Save the ODT file to PDF
            doc.SaveToFile("OdtToPDF.pdf", FileFormat.PDF);
        }
    }
}

Imports Spire.Doc

Namespace ConvertOdtToPdf
    Friend Class Program
        Private Shared Sub Main(ByVal args As String())
            'Create a Document instance
            Dim doc As Document = New Document()
            'Load an ODT file
            doc.LoadFromFile("Sample.odt")

            'Save the ODT file to PDF
            doc.SaveToFile("OdtToPDF.pdf", FileFormat.PDF)
        End Sub
    End Class
End Namespace
