What is a PPT file?
A .PPT file is a Microsoft PowerPoint Presentation (Legacy). It holds presentation slides with text, images, shapes, and animations. Microsoft created this file format for early versions of Microsoft PowerPoint. Most .PPT files use a legacy binary structure known as the PowerPoint 97-2003 format. However, because file structures change over time, a .PPT file might also contain a compressed archive structure. Because .PPT has multiple possible meanings, we recommend using viewer.online/ppt to identify the actual format of your file.
How to open PPT files?
You can open .PPT files using desktop software like Microsoft PowerPoint, Apple Keynote, or LibreOffice Impress. If you do not have presentation software installed, viewer.online/ppt analyzes .PPT files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Software and tools
If you need to share a .PPT file with others, modern file formats provide better compatibility. We recommend file conversion to sensible target formats like .PPTX or .PDF on convert.guru. For developers and command-line users, libraries like Apache POI can extract data and text from legacy Microsoft Office documents programmatically.
Summary
viewer.online/ppt directly opens and previews .PPT files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
