How to open a .pptx file
Quick, free ways to open PPTX on any system.
A .pptx file is a Microsoft PowerPoint Open XML Presentation. If double-clicking does nothing, your computer simply does not have an app that reads PPTX yet. Here is how to fix that on each operating system, using free software wherever possible.
Open a .pptx file step by step
- Confirm the file really is a .pptx. Drop it into the WhatFileType file identifier, which reads its signature without uploading anything.
- On Windows, open it with PowerPoint or LibreOffice Impress.
- On Mac, use PowerPoint or Keynote.
- On Linux, try LibreOffice Impress or OnlyOffice.
- Still stuck? Convert the .pptx to PDF, which opens more widely.
