KEY Document Format

KEY Converter

KEY is the name of the format for files created by Apple’s Keynote presentation app. Keynote is an alternative to presentation software like PowerPoint and Prezi, and includes functions like layout templates, animations and embedded videos. KEY presentations can be created from blank slides or from templates provided within the application. You can also play a KEY presentation on a screen while reading the notes on your device.

Along with Numbers and Pages, Keynote is installed as standard on iOS, iPadOS and macOS as part of the iWork suite. Apple users often use the in-built app because it’s available across their devices without extra downloads or subscriptions. However, the drawback with KEY files is that you need an Apple device to view and edit them. The files can't be opened by other presentation programs like PowerPoint or Google Slides, so to view the files on a Windows or Android device you would first need to convert the KEY files to another format like PDF or PPTX. You can do this either by exporting the presentation from Keynote to a different format, or by using a conversion tool.

PPTX Document Format

PPTX Converter

The PPTX format was developed by Microsoft and has been the default format for PowerPoint files since 2006. Along with similar updates for other Microsoft Office formats, it was designed to replace the older PPT format. The additional X at the end represents the open XML format that makes it easier for users to share and view Microsoft Office files in other programs.

Microsoft PowerPoint is used mostly for creating and delivering presentations, which can include text, graphics, animations, embedded video content and interactive elements. It is also commonly used by organisations and students to create reports, which are usually converted into PDF before sharing or publishing. As well as opening in PowerPoint itself, PPTX files will also open in Google Slides, Apple Keynote and LibreOffice. You can also use PowerPoint to save files into the older PPT format, as well as to save PowerPoint slide shows into PPS or PPSX format.
