What is MIME type "application/oxps"?

A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.

application/oxps is the MIME type used for OpenXPS documents. These files follow the Open XML Paper Specification, a format designed for print-ready and fixed-layout documents.

OpenXPS files retain the exact layout and formatting created by the original document author. They preserve fonts, images, and page settings. This ensures that the document appears the same on any device or when printed.

Files using this MIME type typically have markers like XPS or OXPS.

The format is based on XML. It packages content in a way similar to a ZIP file. This structure helps programs read and render the document accurately. For more details, check the Open XML Paper Specification.

FAQ

What is a MIME type?

A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.

MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.

MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.

How do I find the MIME type for a file?

You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.

Why are multiple MIME types listed for one extension?

Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
