What is a KEY file?
A KEY file is a presentation document created by Apple Keynote, part of the iWork productivity suite. Technically, the format has evolved through two primary iterations: a package directory (bundle) containing XML data and media assets (Keynote '09), and a single-file Zipped archive using Protocol Buffers (Protobuf) for efficient serialization (Keynote 2013 onwards). It utilizes a proprietary schema to store slide geometry, animations, and media, distinct from the Office Open XML standard.
How to open a KEY file
Native access is exclusive to macOS, iOS, and iPadOS devices via the Apple Keynote application. Users on Windows or Linux can view and edit these files via iCloud Keynote in a web browser. Conversion to PDF or PPTX is often required for offline viewing on non-Apple systems. LibreOffice offers limited import capabilities for older version 09 files but struggles with modern Protobuf-based KEY files.

What is a PPT file?
The PPT format is the legacy binary file standard used by Microsoft PowerPoint from versions 97 through 2003. It utilizes the Compound File Binary Format (CFBF), a structured storage container that organizes data into streams and storages, functioning primarily as a file system within a file. PPT files store presentation data-including text, embedded images, audio, and formatting-in binary records rather than XML, which results in larger file sizes and higher corruption risks compared to the modern OOXML standard.
How to open a PPT file
Modern versions of Microsoft PowerPoint retain backward compatibility for opening and saving PPT files. Native support is also available in macOS via Keynote and in Linux distributions via LibreOffice Impress or OpenOffice Impress. Google Slides provides cloud-based rendering of PPT files, though complex formatting or legacy OLE objects may require conversion to the newer Google Slides format for full editing capabilities.
