What is XPS? A thorough guide to the XML Paper Specification

If you have ever encountered the term “what is XPS” and wondered how it differs from more familiar document formats, you are in the right place. XPS, short for the XML Paper Specification, is a fixed-layout, page-centric format designed to preserve the precise appearance of a document across devices and platforms. In this guide we will explore what is XPS, how it works, its history, practical uses, and how it stacks up against competing formats such as PDF. We’ll also cover practical tips for creating, viewing, converting, and archiving XPS files.

What is XPS? A concise definition

What is XPS? In essence, XPS is a document format that records the exact layout, typography, graphics and colours of a page in a structured, portable package. The XML Paper Specification was developed by Microsoft to provide a fixed-layout alternative to word‑processing formats, one that could be printed consistently regardless of software or hardware differences. The result is a file type that captures the intended appearance of a document, making it well-suited to distribution, printing perfection, and archival storage. Although not as ubiquitous as PDF, XPS remains a legitimate option for certain workflows, especially within Windows environments where the format originated.

The core idea behind XPS

At its heart, XPS focuses on the concept of fixed-pages. Unlike editable text formats where the flow of content can reflow depending on the viewer, XPS fixes the content to pages with specified dimensions, fonts, vector graphics and embedded resources. This makes it easier to guarantee that a document will look the same when printed on different machines. The emphasis on a precise page geometry is what distinguishes XPS from many other formats that prioritise reflowable text or interactive elements.

XPS versus PDF: key distinctions

When considering what is XPS in relation to PDF, several contrasts emerge. PDF is widely adopted for both viewing and printing, and it has matured with extensive accessibility and interactive features. XPS, by comparison, has historically been more tightly integrated into the Windows ecosystem and uses XML-based packaging. In practice, both formats offer faithful page replication, but PDF tends to enjoy broader cross‑platform support and a larger ecosystem of tools. For archival use, PDF/A is often preferred, whereas XPS may still serve specific Windows-centric workflows, especially where native XPS tooling is available.

Origins and evolution: a brief history of the XML Paper Specification

The XML Paper Specification originated in the early 2000s as Microsoft sought to provide a robust, print‑oriented format that could be easily processed and stored. What is XPS became a visible part of Windows software at the time, with a dedicated XPS Document Writer acting as a virtual printer. Over time, Microsoft refined the specification and, in some markets, introduced an open variant known as OpenXPS (OXPS). This moved the format toward greater openness and cross‑platform compatibility, reflecting industry demand for a stable fixed-layout format beyond the Windows ecosystem. While PDF remained the dominant fixed-layout format for many organisations, XPS and its OpenXPS evolution offered an alternative that some organisations continued to rely on for specific internal workflows, government archives, and printing pipelines.

How XPS works: structure, packaging and content

Understanding what is XPS in practical terms involves grasping its structure. An XPS file is not a single flat document; it is a packaged collection of XML and binary parts stored within a container, commonly referred to as an XPS Package. In Windows, this packaging approach is built upon the Open Packaging Conventions, a familiar framework that also underpins other modern document formats. Within the package you will typically find a hierarchy that mirrors the page structure of the document: a FixedDocumentSequence, which references one or more FixedDocument objects, each containing FixedPage objects that represent individual pages. On each FixedPage, you will encounter content such as text, vector shapes, images and embedded resources, all arranged with precise coordinates to reproduce the layout faithfully.

Key components in an XPS package

• FixedDocumentSequence: the root of the document’s page-order information
• FixedDocument: a collection of pages treated as a unit
• FixedPage: the exact representation of a single page
• Glyphs and paths: vector and font data that render text
• Resources: images, fonts and embedded media used on pages
• Relationships and content types: metadata that helps software navigate the package

Because the content is defined in XML with a fixed layout, the visual result is predictable. This makes XPS a good choice for documents where precise alignment and optical fidelity are critical—for example, print-ready marketing collateral, forms, or government documents that require a stamped, unalterable appearance. It is also worth noting that fonts can be embedded within the package, ensuring that the text displays as intended even when the original fonts are unavailable on the viewer’s system.

OpenXPS and the modern variant

OpenXPS (OXPS) is widely discussed as the modern incarnation of the XML Paper Specification. While the traditional XPS remains relevant in certain contexts, OXPS reflects an emphasis on openness and interoperability. In practice, many contemporary Windows workflows transition between XPS and OXPS depending on the application, operating system version, and available tooling. The Open Packaging Conventions used by OXPS contribute to smoother cross‑platform handling and easier long‑term access, which can be advantageous for archival projects that prioritise durable, standards-based packaging.

Creating XPS: how to generate XPS documents

One of the most practical questions in the realm of what is XPS is how to create an XPS file. Windows provides built-in options that make this straightforward. The classic approach is to use the XPS Document Writer, which appears as a virtual printer. When you choose Print and select XPS Document Writer as the printer, the system saves the current document as an XPS file. This makes it simple to convert documents from a wide range of applications into XPS without needing specialised software.

Creating XPS on Windows: a quick guide

1. Open the document you wish to convert to XPS.
2. Choose Print from the application’s menu.
3. Select the XPS Document Writer as the printer.
4. Click Print or Save, then choose a location and filename for the .xps file.

Beyond the built‑in printer driver, many applications offer explicit “Save as XPS” or “Export to XPS” options. In corporate environments, IT departments may also implement automated pipelines that generate XPS as part of a document management workflow. For OpenXPS workflows, you might encounter software that saves in the Open Packaging Conventions-compatible format, particularly when dealing with newer Windows versions or cross‑platform toolchains.

Viewing and reading XPS files

To view an XPS file, you typically use a dedicated viewer. In Windows, the XPS Viewer provides a straightforward way to inspect documents page by page. The XPS Viewer supports essential features such as zooming, searching text, and printing. In added to Windows, third‑party viewers and editors offer more advanced features, including annotations, form filling, and integrated conversion options. If you need to collaborate with colleagues who use different operating systems, consider converting XPS files to PDF or another widely supported format to maximise accessibility.

What is XPS good for? Practical use cases and benefits

Why use XPS rather than another fixed-layout format? There are several compelling scenarios where What is XPS translates into practical benefits:

• Guaranteed visual fidelity: XPS ensures that pages print exactly as designed, with consistent typography and layout across devices.
• Document archiving: its structured packaging and XML underpinnings support long‑term readability when combined with robust storage practices.
• Print workflows: for organisations with Windows‑centric print pipelines, XPS integrates smoothly with existing printing and document production systems.
• Security and integrity: digital signatures and the ability to embed fonts help preserve authenticity and legibility over time.
• Accessibility considerations: as with other fixed-layout formats, accessibility tooling varies; however, XPS content can be navigable with appropriate software, especially when alternative text and metadata are provided.

In practice, what is XPS used for often reflects an institution’s software ecosystem and archival requirements. For organisations that rely on Windows-based document production, XPS remains a natural option to preserve exact page appearance, particularly for formal documents, compliance packs, and printable templates that must reproduce identically across printers and locations.

Open packaging, fonts and accessibility: deeper considerations

Delving a little deeper into what is XPS reveals nuances that practitioners should consider. In fixed-layout formats, the precise placement of text and graphics means that the viewer must render fonts accurately. Embedding fonts in the XPS package helps prevent substitution and distortion. However, font licensing and embedding permissions can influence whether a specific font can be embedded, which can affect portability. Accessibility is another important consideration. While PDFs have mature accessibility features and tagging standards, XPS accessibility depends on the viewer’s capabilities and the presence of semantic information within the XML content. When accessibility is a priority, some organisations favour alternate formats or ensure that XPS documents are generated with accessible metadata and structure.

XPS in printing and long-term preservation

For professional printing, the predictability of XPS is attractive. The fixed-page model ensures that the exact layout is preserved from screen to print, which can minimise layout shifting or content reflow during production. For long‑term preservation, XPS’s XML-based packaging and the existence of a clearly defined structure contribute to stable archival formats. When combined with metadata, versioning practices and controlled access, XPS can be a viable part of a curated archival strategy. Nevertheless, for many organisations, PDF/A remains the default choice for archival due to its widespread support and enduring ecosystem. If your aim is durable storage with a fixed appearance, XPS can be considered alongside PDF/A, with consideration given to your software stack and accessibility needs.

Alternatives and complements: what is XPS compared with other formats?

When evaluating formats in the context of what is XPS, several alternatives come into play:

• PDF and PDF/A: the most common fixed-layout formats for distribution and long‑term preservation
• OpenXPS (OXPS): the more open, modern sibling of XPS, designed for cross‑platform compatibility
• ePub: a reflowable format prioritising readability on varying screen sizes (less suitable for fixed layouts)
• Scalable Vector Graphics (SVG) and SVG‑based documents: used for precise vector graphics with high scalability

In practice, the choice between XPS, OXPS, and PDF family formats hinges on factors such as platform compatibility, workflow integration, archival requirements and the availability of suitable tooling. For many organisations, PDF remains the default, while XPS is reserved for Windows-centric tasks where the native toolchain delivers clear advantages.

Common questions about what is XPS

What is XPS used for in business environments?

In business settings, XPS is often used for secure distribution of print-ready documents, forms, and templates where the intent is to preserve exact layout. Its packaging approach supports consistent reproduction across printers, and its XML foundation can help with automated processing and indexing in some document management systems.

Is XPS still supported in modern Windows versions?

Yes, XPS remains supported in modern Windows environments through the XPS Viewer and, historically, the XPS Document Writer. OpenXPS (OXPS) variants are also common, providing a more open approach to the same underlying concept. However, across different platforms, tool availability varies, so compatibility should be assessed in light of your software stack.

Can XPS be converted to PDF or other formats?

Converting between formats is a routine task. Numerous tools and software packages can convert XPS to PDF, image formats, or other document types. Conversely, you can often create XPS directly from many applications via a built-in export or a virtual printer. When converting, verify that fonts, images and colour profiles are preserved as needed for your use case.

Practical tips for working with XPS

Whether you are just answering the question “what is XPS” or actively using the format in a workflow, these practical tips can help you work more effectively:

• Leverage native Windows tools first: use the XPS Document Writer to generate XPS from any printable document, and view with XPS Viewer for quick checks.
• Keep an eye on fonts: embed fonts where possible to avoid substitution issues when sharing XPS files with others.
• Store alongside metadata: attach descriptive metadata and versioning to XPS files to support long-term discovery and integrity checks.
• Consider accessibility early: structure and annotate XPS documents where accessibility is a priority, and provide alternative formats if required.
• Plan for conversion: if your audience uses non-Windows platforms, offer PDF or OpenXPS alternatives to maximise accessibility.

Best practices for archiving XPS documents

When archiving what is XPS in a way that stands the test of time, consider the following best practices:

• Use well-defined naming conventions and include version numbers in file names
• Preserve the original XPS packaging structure and avoid unintentional alterations
• Document the generation process: note software versions, printer drivers, and any fonts embedded
• Store XPS files in a durable, redundant storage system with regular integrity checks
• Provide descriptive, machine-readable metadata to facilitate future search and retrieval

Frequently asked questions about what is XPS and how to use it

Can XPS be edited after creation?

Editing an XPS file directly is not typical, since its strength lies in fixed layout. Most workflows involve recreating or exporting from the source application rather than editing the XPS package itself. Some third‑party tools offer limited editing capabilities, but for precise control and consistency, editing the original document and re-exporting to XPS is recommended.

Is XPS compatible with Linux or macOS?

Native support for XPS on non-Windows platforms has historically been limited. Linux environments can access XPS via third‑party viewers or converters, and macOS users often rely on cross‑platform tools or conversion to PDF. For seamless collaboration, providing PDF copies alongside XPS files is a sensible approach.

What does it mean to use OpenXPS?

OpenXPS represents the more open, standardised variant of the XML Paper Specification. It aligns with modern open packaging conventions and strives to improve cross‑platform compatibility. If you are deciding between formats, consider whether your workflow benefits from the openness and broader tooling associated with OpenXPS.
