Convert Word documents to PDF
Word documents often cause formatting issues across devices. Converting them to PDF ensures:
- Pixel-perfect layouts.
- Preserved fonts, styles, tables, headers, footers, and images.
Syncfusion provides a robust Word-to-PDF conversion API that ensures your documents retain their exact layout, formatting, and visual consistency across all devices.

- Then, refer to the following code example to convert a Word document to PDF.
// Instantiation of DocIORenderer for Word to PDF conversion using (DocIORenderer render = new DocIORenderer()) { // Converts Word document into PDF document using (PdfDocument pdfDocument = render.ConvertToPDF(document)) { // Saves the PDF document to MemoryStream MemoryStream stream = new MemoryStream(); pdfDocument.Save(stream); // Save and launch the PDF document SaveService saveService = new(); saveService.SaveAndView("Sample.pdf", "application/pdf", stream); } }
Note: This example works in .NET MAUI, ASP.NET Core, and other .NET platforms. For platform-specific setup, refer to our documentation.

Convert image to PDF
Combine multiple images into a single PDF for easy sharing and archiving.

Steps to convert an XPS file to PDF:
- Install the Syncfusion.XpsToPdfConverter.Net NuGet package in your project.
- Then, run the following code example.
// Initialize XPS to PDF converter XPSToPdfConverter converter = new XPSToPdfConverter(); // Open the XPS file as stream using (FileStream fileStream = new FileStream("Input.xps", FileMode.Open, FileAccess.ReadWrite)) // Convert the XPS to PDF using (PdfDocument document = converter.Convert(fileStream)) { // Create a MemoryStream to store the PDF MemoryStream stream = new MemoryStream(); // Save the document into the stream document.Save(stream); }
