The provided code example offers a comprehensive approach to converting documents from DOCX to PDF format.

To convert from Microsoft Word to PDF, the first step is to create an instance of the DocxToPdfRenderer class. This class serves as the gateway to various functionalities for DOCX to PDF conversion. By invoking the RenderDocxAsPdf method and providing the filepath to the source DOCX file, you will receive the PDF document as PdfDocument object.

Once the PDF document has been generated, you have the power to apply further manipulation. This includes tasks such as exporting the PDF as PDF/A or PDF/UA, adding a digital certificate to enhance security, and much more.

You can not only convert DOCX to PDF but also make changes to the PDF as needed after the conversion. You can customize the PDF to fit your specific needs.
