Forked from Oracle's Open Office suite, Libre Office is essentially the same, with a few subtle improvements that those who use either may not be able to spot unless they are specifically looking for something (for example, Libre Office supports more languages than Open Office).

Just as Open Office is an alternative to Microsoft Office (and Corel's Office applications, to a lesser extent), Libre Office fulfills the same role to Open Office. pptx, and natively supports Open Office Impress presentation files. Impress can save its work directly as a PDF file, and also features the ability to import its presentation as a SWF file allowing it to be played on any computer with Adobe Flash Player installed. Like most of the applications in Libre Office, which is in itself a fork of the Open Office software, Impress is essentially a rebranded and open-source version of Open office Impress. The Libre Office Impress is part of the Libre Office productivity suite, a presentation software similar to Microsoft Office’s PowerPoint, and powered with similar features and capabilities.
