Choose an output format
Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.
Convert & download
Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.
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.
