The Office Editing for Docs, Sheets & Slides Chrome extension is the first item on this list. Since it’s arguably the simplest way to open and edit Microsoft PowerPoint files for free, this extension is at the top of the list.
- All you need to do is drag and drop any PPT or PPTX file into the Chrome browser window after it has opened.
-
Let’s move on to Google Slides. Similar to Google Sheets or Docs, but for PowerPoint presentations rather than Word or Excel, is Google Slides.
- PPT and PPTX files can also be opened with it. To get started, simply navigate to the "FILE" header in Google Slides. Simply click IMPORT SLIDES, UPLOAD, and choose your file from there.
-
We have LibreOffice next. Developed over a ten-year period, LibreOffice is a completely free and open-source program. It performs admirably in its role as a free substitute for the Microsoft Office suite.
- This is an excellent choice if you want to start from scratch when creating a PPT or PPTX file. It functions pretty much the same as PowerPoint except without the cost.
-
There is Apache OpenOffice as an alternative to LibreOffice. Since both programs are forks of an earlier project, they are both free and open-source. This much is clear even from the naming conventions: Impress is the name of OpenOffice’s version of PowerPoint.
-
An online solution is a good option if you don’t want to install anything on your computer. You can upload your files to the internet and view them with the help of Aspose’s online PowerPoint viewer.
-
The Online Document Viewer is the last option. You can upload and view documents, including PPT and PPTX files, using this online web service.

Click on FILE > EXPORT.

To create a PDF or XPS document, click CREATE PDF/XPS DOCUMENT first.
-
Select the destination for the file save in the PUBLISH AS PDF OR XPS dialogue box. You can change the name by entering it in the FILE NAME box.
-
To achieve a higher quality, choose STANDARD under OPTIMIZE FOR (for instance, if you intend to print it). If you wish to send the file as an email attachment, for instance, choose MINIMUM SIZE to reduce its size.
-
To customize the presentation’s appearance as a PDF, click OPTIONS.
-
Choose CURRENT SLIDE under RANGE if you only want to save the current slide as a PDF.
-
Enter the range of slide numbers in the FROM and TO boxes in SLIDES(S) to save a subset of slides as a PDF.
-
Undoubtedly, Microsoft PowerPoint is the application used to open PPTX files because it is the creator and developer of the format.
-
Without PowerPoint, Windows users can open, edit, and convert files using File Viewer Plus.
-
The .pptx file type is supported by numerous other office suites.
-
You can download Apache OpenOffice Impress, an open-source and cost-free PPTX file viewer, to use on Linux, Mac OS, Windows, and other operating systems.

Another free program that works with several operating systems is LibreOffice Impress.
-
Additionally, Google Slides, a free online file viewer and opener that lets you edit slides, can be used to open PPTX files.
-
All you have to do to open a PPTX file is open one of the programs, select File, and then select Open.
