The WordPerfect text and graphics file is a proprietary word processing format originally developed by Satellite Software International and currently maintained by Corel Corporation. It is primarily used to store complex documents containing formatted text, mathematical tables, and embedded vector or bitmap graphics. Although largely superseded by modern XML-based standards, it remains an important legacy format within legal and government sectors that require precise control over layout and document structure.
