One of the most famous formats for creating presentations is PPT. The .ppt format is assigned to files that were created in Microsoft PowerPoint and contain slide show elements. Modern versions of office software use the PPTX format, but some interpreters can run this format even in the 2007 version. The PPT file is a product of Microsoft PowerPoint 97-2003. Newer versions of PowerPoint have replaced this format with PPTX. PPT files are often used both for educational purposes and in the office, for everything from study to presenting information to an audience.
The Portable Document Format (PDF) is a versatile file format that preserves the fonts, images, and layout of the original document, regardless of which of many platforms and which of many applications the document was created on. It was initiated by Adobe and was originally intended for electronic presentation of printed materials. PDFs look the same no matter what device they are viewed on. Whether you're using Windows 10, Mac, Chrome OS, Android, Windows Phone, iPad, or Windows XP - on any software or hardware, PDFs remain the same.
