Programs to open PPTX files

Whether you have a Windows PC, a Mac or a Linux-equipped computer, you are sure to find a program to open PPTX files. Below are some of the best: choose the one that seems best suited to your needs and use it following the instructions below.

Microsoft PowerPoint (Windows/Mac)

How to open PPTX

A guide on how to open PPTX can only begin with Microsoft PowerPoint, the presentation software included with Microsoft Office. As you surely know, Office is a paid product and therefore requires the purchase of a license, but Microsoft allows you to try it for free for 1 month.



To be more specific, the only way to try Office free for 1 month is to activate a subscription to the service Office 365 Home that for 10 euro / month (after the free trial) allows you to use all the applications of the Office package on 5 computers, 5 tablets and 5 smartphones. It also offers 1TB of space on OneDrive (usable by a maximum number of 5 users) and 1 hour of free Skype conversations (always usable by a maximum number of 5 users).

Activating your Office 365 subscription is free, which means you can download and use Office at no cost, but if not turn off automatic subscription renewal, on the 30th day of subscription you will be charged 10 euros for the following subscription month (during registration, in fact, you will be asked to provide a valid payment method between credit card, PayPal or bank account).

There is also a "lighter" version of Office 365, 365 Office Staff, which costs 7 euros / month and limits the use of the apps and services included in the subscription to a single user and a single device, just as the traditional version of Office still exists, which is paid one-time (149 euros), but sadly neither of them offers a free trial period.



Without these necessary premises, if you intend to try the free version of PowerPoint, connect to the Microsoft website and click on the button first try free e poi quello Try free for 1 month.

At this point, log in with your Microsoft account (if you don't have one yet, find out how to create a Microsoft account in my tutorial dedicated to the topic) and click on the item Add a payment method located in the left sidebar to associate a payment method to your account. As already mentioned, you can choose between credit / debit cardPayPal e SEPA direct debit and before the Office trial expires (or rather, before the 30th day from the activation of your Office 365 plan) you will not be charged.

When the operation is completed, check the correctness of the data you entered in the Office 365 registration form and click in sequence on the buttons SaveNEXTBuy Now e Continue.

To disable the automatic renewal of Office 365, instead, click on the button Manage accounts, select the voice Turn off automatic renewal from the page that opens, type the password of your Microsoft account and press the button Confirm cancellation but I will complete the operation.

PowerPoint 2003

Are you using a version of Office earlier than 2007? If it comes to Office 2003, know that thanks to the Microsoft Office Compatibility Pack add-on you can make this version of the suite compatible with all the file formats introduced by Microsoft in Office 2007.

Therefore, if you are unable to view / edit PPTX documents because the 2003 version of Office is installed on your computer, solve the problem by connecting to the Microsoft site and downloading the Compatibility Pack above: just click on the button Download.


Once the download is complete, you can install the add-in for Office 2003 by opening the file FileFormatConverters.exe, putting the check mark next to the item Click here to accept the Microsoft Software License Terms (o Click here to accept the Microsoft Software License Terms) and pressing the buttons in sequence Continue e OK.

LibreOffice (Windows / Mac / Linux)

You have no intention of purchasing Microsoft Office or any other paid software for aprire and PPTX file? Then I highly recommend you download LibreOffice, a great free and open source alternative to Microsoft Office compatible with Windows, macOS and Linux.

App to open PPTX files

Smartphones and tablets now have very advanced potential, let alone if they cannot reproduce and edit PPTX files! Here I am in fact to point out some app to open and edit PPTX files.

PowerPoint (Android/iOS/Windows Phone)

To have maximum compatibility with PPTX files and exploit (almost) all the potential of PowerPoint on the go, you can rely on  mobile version of PowerPoint which is available for iPhone / iPad, Windows Phone and for Android devices and is free on all devices with dimensions equal to or less than 10.1 ″ (on larger devices it requires a subscription to the Office 365 service).

How to open PPTX

The PowerPoint app includes most of the basic PowerPoint features for computers (it lacks several advanced features) and also supports cloud storage services, such as OneDrive, Dropbox, and iCloud (on Apple devices only). Its operation is extremely intuitive since it has an interface practically identical to that of the desktop counterpart.

WPS Office (Android/iOS/Windows Phone)

WPS Office, a free productivity suite (in its basic ad-supported version) that allows you to create, view and edit all major Microsoft Office file formats on Android, iPhone / iPad and Windows Phone devices.

How to open PPTX

The app does not present major compatibility problems (at least with not too elaborate documents) and supports both saving and uploading of documents from cloud storage services, such as Dropbox and Google Drive. A must try if the PowerPoint mobile app doesn't suit your needs.

Other interesting apps that I would like to point out are: Google Presentations (Android / iOS) which allows you to view and edit presentations via Google Drive and AndrOpen Office (Android), an almost perfect port of OpenOffice for Android. They are not as comfortable or practical as PowerPoint for smartphones and tablets, but should be taken into consideration.
