PPSX is a presentation file format used by Microsoft PowerPoint. It’s similar to PPTX but is specifically designed for creating slideshows. PPSX files open directly in slideshow mode, making them ideal for presenting during meetings or conferences. They can include text, images, multimedia, and animations.
PNG is a lossless image format that supports transparency, making it ideal for logos, icons, and web graphics. Unlike JPEG, PNG doesn’t lose any image data during compression. It retains high-quality detail, especially in images with sharp edges, and is commonly used for design work where transparent backgrounds are required.
