What file extension is used to save an MS PowerPoint 2021 presentation?
.pptx
Microsoft Office applications use the Office Open XML (OOXML) file format family, introduced starting with Office 2007 and continued through Office 2021/365. These formats are recognisable by the trailing "x", which signals that the file is a zipped package of XML documents (rather than the old proprietary binary format), making files smaller, more robust to corruption, and easier to integrate with other software.
| Application | Modern (Open XML) Extension | Legacy Binary Extension (pre-2007) | File Type |
|---|---|---|---|
| PowerPoint | .pptx | .ppt | Presentation / slide deck |
| Word | .docx | .doc | Word-processing document |
| Excel | .xlsx | .xls | Spreadsheet workbook |
So, for MS PowerPoint 2021, the default save format for a normal presentation is .pptx. (A macro-enabled presentation would instead be saved as .pptm, and PowerPoint can also export to .pdf for a fixed, non-editable version, but that is not its native "save" format.)
The other options belong to different applications entirely: .docx is Word's document format, .xlsx is Excel's spreadsheet format, and .pdf is a universal, application-independent document format used for sharing/printing rather than for native, editable PowerPoint files — none of these is what PowerPoint uses to save its own presentations.
