What is an XPS file?

XPS (XML Paper Specification) is a fixed-layout document format developed by Microsoft and later standardized as ECMA-388 (Open XML Paper Specification). It serves as a page description language similar to PDF, utilizing a ZIP-based container to hold XML markup (XAML) for layout, embedded fonts, and vector graphics. The format ensures document fidelity across different printers and displays by defining the precise position of every element on the page.

How to open an XPS file

Windows operating systems (Vista through 10) include a native 'XPS Viewer' application. On Windows 11, this feature is optional and may require manual activation via 'Optional Features'. Non-Windows users must rely on third-party tools like MuPDF or online conversion services to view or convert the content to PDF.

What is a MOBI file?

The Mobipocket eBook format (MOBI) is a binary distribution format developed by Mobipocket SA in 2000, utilizing the Open eBook (OEB) standard and XHTML for reflowable content layout. Encapsulated within a Palm Database (PDB) container, MOBI files employ either the LZ77-based PalmDOC compression or the proprietary HUFF/CDIC algorithm to minimize file size. The format supports Digital Rights Management (DRM), metadata indexing, and javascript capabilities, serving as the foundational architecture for Amazon's proprietary AZW format before the adoption of KF8.

How to open a MOBI file

Native support for MOBI is restricted primarily to Amazon Kindle hardware and legacy Mobipocket readers. On Windows, macOS, and Linux, users require third-party eBook management software such as Calibre, which offers comprehensive viewing and conversion capabilities. Alternatively, the Kindle Previewer tool provided by Amazon or multi-format readers like FBReader and Sumatra PDF can render the unencrypted content of these archives.
