What is a PPT file?
A PPT file is an editable slide show created by Microsoft PowerPoint or exported by another presentation program, such as OpenOffice Impress or Apple Keynote. It may include formatted text, bullet points, images, movies, sound effects, and music. PPT files are commonly built from one of many templates included with the PowerPoint software, but may also be created from scratch.
You may encounter PPT files in home, school, and business environments when creating, saving, and presenting presentations. The Microsoft PowerPoint Presentation (PPT) binary format was introduced in 1987 with the release of PowerPoint. It was the primary file type used to save PowerPoint presentations until it was replaced in PowerPoint 2007 with the Open XML Presentation (.PPTX) file format.
While you will most likely see PPTX files more often than PPT files, some users with older versions of PowerPoint may still save their presentations as PPT files. You may receive PPT files from friends, family members, or co-workers via email or download them from a website or cloud storage service.
Common PPT Filenames
Presentation1.ppt - The default filename Microsoft PowerPoint gives to new presentations prior to PowerPoint 2007, which now uses Presentation1.pptx.
How do I open a PPT file?
You can open PPT files with Microsoft PowerPoint in Windows and macOS. PowerPoint is the best application for opening PPT files because it fully supports the formatting of the presentations, which includes the placement of text, slide transitions and effects, and images and shapes in the presentation. PowerPoint is also available for Android and iOS devices.
There are a large number of other presentation programs that can open and edit PPT files but they may not fully support the formatting of the presentation files. Alternative programs include Corel Presentations (Windows), Apple Keynote (Mac), and Apache OpenOffice Impress (multiplatform). If you are a Mac user simply looking to view a PPT file, you can use Apple Preview, which comes bundled with macOS.
You can also open PPT files with various web programs. Google Slides is a free option you can access with a Google account. The web tool allows you to upload a PPT file and view, edit, save, and convert the presentation.
