What is PowerPoint presentation?
The binary PowerPoint presentation format. Convert slides locally to PPTX, OpenDocument Presentation, or PDF.
The browser Office engine needs a current desktop Chrome or Edge browser, an approximately 79 MB download, and at least 1 GB of free memory. The workspace shows when a hosted fallback is needed. Fonts and unsupported document features can affect the result. Macros and external-link updates are disabled.
Technical details
Legacy Microsoft Office binary documents use application-specific records in a Compound File Binary container rather than OOXML's ZIP/XML packaging. [1]
Background and compatibility
These formats belong to the pre-OOXML Office generation; modern office applications provide compatibility modes, but round-tripping can alter features. [1]
