Java/ Convert PPS/PPT to PPTX

PPS is a PowerPoint Show format that opens in full-screen slideshow mode and automatically exits when finishing displaying . While PPT is the default file extension for saving presentations in PowerPoint 2003 and earlier versions. Sometimes, you may receive a PowerPoint presentation in .pps or .ppt format. In this article, you will learn how to programmatically convert them to PPTX format using Free Spire.Presentation for Java.

Import jar dependency

● You can download the free library and unzip it, and then add the Spire.Presentation.jar file to your project as dependency.

● Or you can directly add the jar dependency to your maven project by adding the following configurations to the pom.xml.
