Microsoft's PowerPoint has been leading the way on presentation software for more than 30 years. 

A key component of the hugely successful Microsoft Office productivity suite, it has become a hugely valuable tool for helping ideas come to life. However, all the bells and whistles of an Office 365 subscription might not be suitable for you. In this article, we'll show you how to use Microsoft PowerPoint completely legally and free of charge.

We’re going to show you how to get your hands on Microsoft PowerPoint for free and all you’re going to need is a free Microsoft account. This is a perfectly legitimate way of accessing Excel, Microsoft just keep is fairly quiet as they would really like you to pay for the desktop version.

If you'd like to purchase Microsoft Office to use on your PC when you're offline, take a look at our buying guide here.

Option 1 - Web Version

Accessing Microsoft PowerPoint and other core Office programs is free via the web, and all you'll need is a Microsoft account. Head over to Office.com and create an account, or log into one that you already have.

Once you’re logged into your Microsoft account on office.com you’ll find yourself presented with this screen:

PowerPoint for Free

At the top here you can select the App you wish to use, everything from Excel, Word and PowerPoint to Outlook and Skype. These are all ‘Web Apps’ which means they’re applications that you use online rather than them being installed on your computer. When you work on a file here, it will be saved to OneDrive, Microsoft's cloud storage service. 

In fact, you probably have Google to thank for this software being available in web app form, as its free Docs, Sheets and Slides software and its integration with Google Drive made it difficult for Microsoft to keep asking users to pay.

The web version of PowerPoint is a more stripped-back version of the software, so the comparison to Google Docs is more reasonable than the full desktop program. Nonetheless, both services should provide everything a regular user is looking for.

Option 2 - Use on mobile

Perhaps again in response to Google, Microsoft's Office mobile applications are completely free and available across modern mobile devices. You can download the Microsoft PowerPoint app for Android and iOS. While Microsoft understandably reserves some premium features for its Office 365 subscription, the mobile apps are still supremely capable and the perfect option if you're looking for some productivity on-the-go.

Option 3 - Get the full version

Of course, if only the fully-fledged version of PowerPoint will do you'll need to subscribe to Office 365. Like Adobe, Microsoft prefer you pay a regular fee to access their software, as opposed to buying it outright. 

On the plus side, this does get you regular updates, which should ensure it is more secure than a big annual release. 

Subscriptions start at £5.99 a month, or £59.99 a year.

A one-off purchase will get you PowerPoint alongside Microsoft Word and Excel for £119.99, but you will be without OneDrive or Skype, services usually included as standard.
