You're going to struggle to do this for free. Word is a proprietary format so anyone who writes code to access it and do it well is unlikely to give it away for free. There are some free doc readers\writers (DocX for example) but none that I know of support conversion to PDF. There are plenty of components that will do this (Spire.Doc, GemBox.Document) but none of them are free.

"Not working for me" is not informative at all!
Seems you haven't read related articles, because an author of second article ("Convert...") provides a custom way to convert word document into pdf.
Congrats!

A little bit of searching leads you to this solution[^]. While it's a Java component, the NuGet brings in everything you need to get this working in .NET.

Hi.,

Please have a look at this link

How to convert word document to pdf in C#[^]

public Microsoft.Office.Interop.Word.Document wordDocument { get; set; }

Microsoft.Office.Interop.Word.Application appWord = new Microsoft.Office.Interop.Word.Application();
           wordDocument = appWord.Documents.Open(@"C:\Users\Desktop\test.docx");
           wordDocument.ExportAsFixedFormat(@"C:\Users\Desktop\test11.pdf", WdExportFormat.wdExportFormatPDF);

Thanks
