What is PPTX?

PPTX is a file format for storing PowerPoint slides. It is used for presentations. It is similar to the PDF format and to a lesser extent to the JPEG format. It is a popular format for digital images and graphics.

How to use the app?

If you have a PPT file, then you can open it using this app. If you don't have a PPT file, then you can create one. You will be able to choose the type of slide you want to create (e.g. image, text, and audio). Then you will be able to choose the content (e. text, table, image, and audio).

After you have created your slide, then you will be able to preview it.
