What is PPTX file format?

PPTX (PowerPoint Open XML) is a file format used by Microsoft PowerPoint, a popular presentation software. PPTX files store presentation data in an XML format and are used to create professional-looking slideshows. They can include text, images, animation, audio, and video elements. A PPTX file is a great way to share presentations with others because it can be opened on both Windows and Mac computers. It also enables users to make and save changes to the presentation without overwriting the original file. Additionally, PPTX files are generally much smaller than PPT files, which makes them easier to share. When creating a presentation in PowerPoint, users can save the file in either a PPTX or a PPT format. To make sure the presentations look the same across all platforms, it’s recommended to always save in the PPTX format. PPTX files can be opened in other presentation software such as Apple Keynote and Google Slides, however some features may be unavailable. Additionally, the file size may be larger than the original PPTX file. Overall, the PPTX file format is a great choice for creating professional-looking presentations. It’s a reliable, cross-platform solution that makes it easy to share presentations with others.
