XPS is a format similar to PDF but uses XML in layout, appearance and printing information of a file. XPS format was developed by Microsoft and it is natively supported by the Windows operating systems. If you want to work with your PDF files on a Windows computer without installing other software, you can convert it to XPS format. Likewise, if you need to share a XPS file with a Mac user or use it on various devices, it is more recommended to convert it to PDF. This article will demonstrate how to programmatically convert PDF to XPS or XPS to PDF using Spire.PDF for .NET.
