In the last two years, the office productivity market has experienced dramatic change. New Web-based applications, new file formats, and new user experiences have risen to prominence as vendors attempt to turn new technologies into a larger share of the highly profitable office productivity market.

Corel WordPerfect Office has long been the leading alternative to Microsoft Office. Now, Corel WordPerfect Office X4 delivers an exciting upgrade to the legendary office suite, directly addressing the needs of today’s PC user, as well as the productivity technology trends of today and tomorrow.

Ask Corel WordPerfect Office users what they love about the suite, and they’ll often tell you that it gives them the features, formatting control, and results that they desire but cannot find in Microsoft Office. Any e-mail client or word processor will suffice for writing a note or memo. But when there’s more at stake, such as when you need to produce a multipage report or when you simply need a document to look just right, you need the unique features and user experience of Corel WordPerfect Office X4.

Supports the latest Microsoft Office file formats (OOXML) and for Open Document Format (ODF). The latest X4 now supports a wide number of PDF editing features, including the option to import and edit PDFs within WordPerfect.
