Do you have a KEY file? So you can open it in Windows

Next, let’s see what a KEY file and what it is used for. As we have mentioned, it is a type of file only compatible with macOS, although there are also ways to open and edit them in Windows. Likewise, we will see different options available to be able to convert them into other file formats.

What is the KEY file used for

A KEY file is a format for create multimedia presentation on apple devices for use from the Keynote app on both macOS and iOS. This type of file contains different slides in which you can include text, images, shapes, graphics, transitions, audio, video and notes. In this way a KEY file is the main file type associated with Keynote, similar to how PPTX files are with Microsoft PowerPoint.

Keynote is one of three Apple productivity apps found in iWork, along with Pages and Numbers. These are versions for Apple of the most popular programs developed by Microsoft, such as PowerPoint, Word and Excel, belonging to the Office package.

Although this makes us think that a KEY file can only be compatible with Apple devices, the truth is that it can also be accessed and used from a Windows 10 and Windows 11 device.

Programs to open and view in Windows

Suppose we have created a presentation using the Keynote application, thus creating a KEY file. Well, it may be the case that you need to be able to open the file, but you don’t have your MacBook, iPhone or iPad handy, but you do have a Windows PC. In this case, we tell you how to open them and see them.

However, we must bear in mind that visualization will never be the same, nor will we be able to get the same attributes and functions of Keynote when opening the KEY file in Windows. Despite the compatibility of some programs, there will always be a loss or change in the format and layout.

In the event that we do not have PowerPoint we can also use a free and free alternative like LibreOffice Impress. Unfortunately, as with PowerPoint, we will not be able to use all the functions of the original KEY presentation, and it is possible that we can lose the formatting, as well as the transition effects that it includes.
