Oxps is a file format used by the Windows operating system to save documents created using the XPS (XML Paper Specification) document format. It stands for Open XML Paper Specification. XPS is similar to PDF format, and it provides users with a high-quality, fixed-layout document format that preserves the formatting and layout of the original document. Oxps files can be opened using the XPS Viewer application built into Windows, or they can be converted to other document formats such as PDF using third-party software. Oxps files are commonly used for creating and sharing documents that require high-quality printing, such as brochures, flyers, and marketing materials.
