Converting from DOCX to PDF for thumbnails

I recently needed to show some thumbnails of docx files online. Here is what I came up with. Please note that this will not create a perfect thumbnail. In fact its quite basic. It allows the user to simply see that the file contains something. Nevertheless, I hope you find it helpful!

public ActionResult GetPDFFromDocx(string fileName, string OriginalName)
        {
            string docxFilePath = GetFileandPath(fileName);
            string tempPdfFilePath = GetFileandPath(Guid.NewGuid().ToString("N") + ".pdf");
            // Open the Word document
            using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(docxFilePath, false))
            {
                // Create a PDF document
                using (PdfDocument pdfDoc = new PdfDocument())
                {
                    // Add a new page to the PDF document
                    PdfPage page = pdfDoc.AddPage();

                    // Get the Word document body
                    Body body = wordDoc.MainDocumentPart.Document.Body;

                    // Render the Word document content to the PDF page
                    using (PdfSharp.Drawing.XGraphics gfx = PdfSharp.Drawing.XGraphics.FromPdfPage(page))
                    {
                        XTextFormatter tf = new XTextFormatter(gfx);
                        tf.DrawString(body.InnerText, new PdfSharp.Drawing.XFont("Arial", 12), PdfSharp.Drawing.XBrushes.Black,
                            new PdfSharp.Drawing.XRect(0, 0, page.Width, page.Height), PdfSharp.Drawing.XStringFormats.TopLeft);
                    }
                    // Save the PDF document to the specified file
                    pdfDoc.Save(tempPdfFilePath);
                }
            }
            // Convert the docx file to pdf
            var gf = GetFileContentResult(tempPdfFilePath, OriginalName);
            // Delete the temporary files
            System.IO.File.Delete(tempPdfFilePath);
            return gf;
        }

Here is the GetFileContentResult:

 public FileContentResult GetFileContentResult(string path, string OriginalName)
        {
            if (!System.IO.File.Exists(path))
            {
                
                return null;
            }
            else
            {
                byte[] fileBytes = System.IO.File.ReadAllBytes(path);
                return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, OriginalName);
            }
        }
