PDF vs XPS: When to Use Which
XPS (XML Paper Specification) was Microsoft's answer to PDF — a fixed-layout document format introduced with Windows Vista. While technically capable, XPS never achieved PDF's universal adoption. Here's an honest look at how they compare and why it matters for your documents.
Understand the key differences between these formats and when to use each one.

| Security features | Encryption, permissions, digital signatures | Digital signatures, rights management |
| Color management | ICC profiles, spot colors | Windows Color System (WCS) |
| File size | Compact with good compression options | Generally larger due to XML verbosity |

Key Differences
The Verdict
PDF is the clear winner in almost every scenario. XPS was a technically sound format but never gained the ecosystem or adoption needed to compete. Microsoft itself has moved away from XPS, removing the XPS Viewer from default Windows installations. Unless you're working in a legacy Windows environment that specifically requires XPS, use PDF.
SublimePDF's client-side architecture is built on WebAssembly and processes files in the PDF open standard (ISO 32000), ensuring compatibility and privacy across all platforms.
