In the realm of presentations, visuals and multimedia elements play a pivotal role in engaging and captivating audiences. Microsoft PowerPoint, a ubiquitous tool for creating presentations, enables users to incorporate a variety of media files such as images, videos, and audio clips to enhance the overall impact of their slideshows. However, as presentations become more dynamic and multimedia-rich, the size of media files can significantly affect the performance and portability of PowerPoint presentations. To address this challenge, PowerPoint offers a built-in feature for compressing media files, optimizing their size without compromising quality.
