The iWork suite consists of three programs: Pages for word processing, Numbers for spreadsheets and Keynote for presentations. All three are able to open, edit, save and share documents from their Microsoft Office counterparts, Word, Excel and PowerPoint. iWork applications will also support other popular file formats including Portable Document Format (PDF), Rich Text Format (RTF) and plain text.
The iWork software suite supports local file storage and integrates with iCloud so end users can synchronize their documents across multiple devices. In 2013, Apple released a beta version of iWork for iCloud, a Web-based version of the suite that allows Mac and Windows users to create and edit documents within a Web browser.
