PPSX Document Format PPSX Converter
The PPSX file format was developed by Microsoft for its PowerPoint presentation program. PPSX is a PowerPoint Show file format and is the replacement for the older PPS format. It was first introduced in 2006, along with updates for other Microsoft Office programs. The X in the name indicates that the files are now XML-based, making them compatible with more programs, including LibreOffice Impress and Apple Keynote.
You can save presentation shows as PPSX within PowerPoint, which is available as part of a Microsoft Office365 subscription. To open PowerPoint Show files for editing in PPTX format, run the PowerPoint program first and then open a PPSX file from the File>Open menu options. If you open a PPSX file without PowerPoint already running, the presentation will usually automatically play as a slideshow, either on a timer or controlled with mouse or keyboard clicks. PPSX files can also be opened by other applications, such as LibreOffice Impress and Google Slides, although some of the formatting features may not be supported.
PPTX Document Format PPTX Converter
The PPTX format was developed by Microsoft and has been the default format for PowerPoint files since 2006. Along with similar updates for other Microsoft Office formats, it was designed to replace the older PPT format. The additional X at the end represents the open XML format that makes it easier for users to share and view Microsoft Office files in other programs.
Microsoft PowerPoint is used mostly for creating and delivering presentations, which can include text, graphics, animations, embedded video content and interactive elements. It is also commonly used by organisations and students to create reports, which are usually converted into PDF before sharing or publishing. As well as opening in PowerPoint itself, PPTX files will also open in Google Slides, Apple Keynote and LibreOffice. You can also use PowerPoint to save files into the older PPT format, as well as to save PowerPoint slide shows into PPS or PPSX format.
