In Editing view, you can add and delete content, and format text. You can also add, delete, duplicate, and hide slides.

You can add SmartArt graphic, pictures, and hyperlinks. Go to the Insert tab to add these.

If you want to add effects or make changes to SmartArt graphics or pictures, click the image, and then use the tools displayed on the tab that appears (SmartArt Tools or Picture Tools).

If you want to see how your changes look in the presentation, switch back to Reading view. On the View tab, click Reading View. Or, click Slide Show to preview the slide show that includes transitions and animations.

PowerPoint Web App saves your presentation automatically while you work on it. You don’t have to save your changes. If you make changes that you don't want to keep, use the Undo command or press CTRL+Z (Windows) or ⌘+Z (Mac).

Microsoft Powerpoint Application

Seamlessly edit in PowerPoint

Editing in PowerPoint Web App is best suited for quick changes, such as making a correction, adding a graphic, or adding some slides. If you want the full set of PowerPoint capabilities, click the File tab, and then click Open in PowerPoint.

PowerPoint Web App opens the presentation directly in your PowerPoint desktop application, where you can work more substantially—for example, if you want to change transitions or edit slide content that is not in placeholders. In PowerPoint, when you click Save, PowerPoint saves the presentation back on the web server.

Note: Opening presentations directly from the browser into the PowerPoint desktop application is supported in Firefox, Internet Explorer (Windows), and Safari (Mac) browsers. In Windows, you must also be using PowerPoint 2003 or later to use this feature (If you are using Firefox, you must also be using PowerPoint 2010). On the Mac, this feature requires Microsoft PowerPoint for Mac 2008 version 12.2.9 or PowerPoint for Mac 2011.
