What is it

Microsoft created XPS in 2006 as a direct competitor to PDF. It's a fixed-layout document format based on XML and ZIP packaging, designed to render identically on any device — exactly what PDF does. Windows Vista shipped with XPS support built in. The XPS Document Writer was a default printer in Windows. Microsoft tried hard.

The world shrugged. PDF had a 13-year head start, universal cross-platform support, and the entire Adobe ecosystem behind it. XPS remained a Windows-only curiosity. Even Microsoft eventually added native PDF support to Office and Windows, implicitly admitting that XPS hadn't caught on.

You'll encounter XPS files from older Windows printing workflows or legacy document archives. Windows 10/11 includes the XPS Viewer (you may need to enable it in Optional Features). For cross-platform viewing, Pagemark XPS Viewer (free) or converting to PDF is the practical solution.

FAQ
How do I open an XPS file?
On Windows 10/11, search for 'XPS Viewer' — you may need to enable it in Settings → Apps → Optional Features. On other platforms, convert to PDF using online tools or Pagemark XPS Viewer.
Should I use XPS or PDF?
PDF. Always. XPS has no advantages over PDF and dramatically less software support. If you receive an XPS, convert it to PDF for long-term access.
