How to Change Master Slide in PowerPoint Online

The Master Slide (or Slide Master) is designed to help you edit your PowerPoint presentation effortlessly. Every version of PowerPoint comes with this feature, but first we'll show you how to do it online.

The master slide is the perfect tool when you have just finished your presentation, but want to make several changes to it. For example, you realized you didn't like the layout, or you realized you were using the wrong font all along. Technically speaking, the Master Slide controls everything except the content of the presentation.

By making changes to your master slide, you can change all the slides in your presentation at once. This is a very useful feature, especially when you have 30 or more slides. Instead of editing each slide individually, you can just go to the Main Slide tab and get the job done in just a few minutes.

For those who prefer to use the PowerPoint web app, the process of changing the master slide is just as easy. Here's what you need to do:

  1. Visit Power Point on your Internet browser.
  2. Sign in to your Microsoft account.
    Notes: You can also just go to and switch to PowerPoint from there.
  3. To create a new PowerPoint presentation, click the "New blank presentation" button. You also have the option of uploading a saved PowerPoint presentation from your computer.
  4. If you've uploaded a presentation, navigate to the "Edit Presentation" tab at the top of the screen.
  5. Switch to "Edit in Browser".
  6. Once you've opened your presentation, select "View" from the top menu.
  7. Click on “Slide Master”.
  8. Edit the slide master.
  9. When you're done, navigate to the "Close Main View" button on the right side of the pane.
    All slides will be updated immediately. When you open the main slide, the editing options are almost limitless. For example, you can insert a new slide or placeholder, change the presentation theme, or hide background graphics. You have the same editing options that you would access on individual slides. However, if you want to make changes to a single slide, the Master Slide feature is not for you.
    Once you're done with your presentation, it will automatically be saved to your OneDrive. If you want to download it to your device, follow the steps below:
  10. Click on the "File" tab in the top menu.
  11. Choose "Download as" from the list of options on the left sidebar.
  12. Select "Download a copy", "Download as PDF", or "Download as ODP".

Using PowerPoint for the web is useful because it allows you to save your presentations online and on your device.
