02

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is an OXPS file?

The OXPS (Open XML Paper Specification) format is a fixed-layout page description language developed by Microsoft and standardized as ECMA-388. It functions as the non-proprietary successor to the XPS format, utilizing a ZIP archive to contain distinct XML markup for page content, document relationships, and embedded resources like fonts and images. Unlike reflowable document formats, OXPS describes the exact placement of text and vector graphics for device-independent printing and viewing.

How to open an OXPS file

Windows operating systems (Windows 8 and later) provide the native 'XPS Viewer' application for decoding OXPS files. On macOS and Linux, native kernel support is absent; users must rely on third-party conversion tools (such as NiXPS) or convert the file to PDF using command-line utilities. It is notable that the legacy XPS Viewer on older Windows systems cannot open OXPS files without a dedicated converter from Microsoft.

What is a PDF/A file?

PDF/A is an ISO-standardized (ISO 19005) variant of the PDF format designed specifically for long-term digital archiving. It embeds all fonts, color profiles, and metadata directly inside the file and prohibits external dependencies, encryption, and JavaScript, ensuring the document will render identically decades from now regardless of which software or fonts are available on the viewing system. It's widely required for legal, government, and institutional record-keeping.

How to open a PDF/A file

PDF/A files open in any standard PDF viewer, including Adobe Acrobat Reader, Apple Preview, and built-in browser PDF viewers, since the format is fully backward-compatible with regular PDF readers. Dedicated archival software such as Adobe Acrobat Pro can also validate that a file meets PDF/A compliance.
