To open and view your PowerPoint file, visit the Office Online homepage and login with your Microsoft account. Now, access the OneDrive and upload your file there. Once you have successfully uploaded your file to your OneDrive account, you can access it in the PowerPoint Online web app. Apparently, one can’t directly upload files to PowerPoint Online, and this is a huge drawback of this. Well, we have found that the PowerPoint Online renders presentations very accurately, and that’s why we recommend it over other suggested tools.

For this, just click the yellow icon on the top bar (marked in the above screenshot) and you would be redirected to the Google Slides automatically. Using Google Slides, you can see advanced view, and also play the slideshow.

Google Slides is a featured cloud based application, and part of Google’s online Office application, Google Docs. You can use it to create, edit and view PowerPoint files. It is deeply integrated with Gmail and Google Drive.
