What is a KEY file?

A KEY file is a generic file extension used by various programs when registering legal copies of the software. It may be saved in a plain text format but generally contains some form of encrypted key string that authenticates the purchase and registers the software.

More Information

Since KEY files are used by various software products, no single program will be able to open them. Instead, you will have to know which program a KEY file corresponds to in order to use it to register the software.

Keynote is one of Apple's three productivity apps that make up iWork, along with Pages and Numbers. These applications are Apple's versions of the more popular PowerPoint, Word, and Excel programs, which are developed by Microsoft and available in the Office suite. The iWork apps are developed for macOS and iOS but can also be accessed using a browser on a Mac or PC through iCloud.

Keynote presentations can be used for academic, business, or personal purposes. You can choose to start your presentation from one of the templates provided with the program or from scratch. When you are finished creating your presentation you can share it directly from your device or through Keynote Live.

You can also export a KEY presentation to another format such as .PDF, .HTML, QuickTime .M4V video, or as a .JPEG, .PNG, or .TIFF image. If you need to open it in Keynote '09 or earlier you can export it in that format, as well. But the most useful export option is to the PowerPoint format, either .PPTX or .PPT.
