Part 1 of 3:
Adding a Picture

Open your PowerPoint presentation. You can add graphics to the background of any slide in your PowerPoint presentation. Open the presentation you want to edit in PowerPoint.

Click the Design tab at the top of the window. This will display the Design tools.

Click the "Format Background" button. You'll find this on the far right side of the Design ribbon. The Format Background sidebar will appear on the right side of the screen.[1]




Click "Apply to All" to set the picture for all slides. The picture is normally just added as the background for the slides you selected. If you want to apply it to every slide, click the "Apply to All." This will set the background of every slide to the new image, including slides that you create later.
Part 2 of 3:
Applying Effects

Check the "Tile picture as texture" to turn the image into a tiled texture. This works best for images that are small and can flow seamlessly into each other.

Adjust the tiling effect with the controls below. You can use these controls to adjust the spacing between the tiled images, whether or not they're mirrored, and the alignment.

Use the transparency slider to adjust the image transparency. This is especially useful if you want to add watermarks to your slides. Setting a background image with a high transparency will allow you to use an image as a watermark without obscuring or distracting from the information on the slides.


Click "Apply to All" to apply the effects to all of your slides. This will change all of the slides in your presentation to use the background image and effects you selected.

Using Slide Master View

Click the View tab in PowerPoint. This will display different view options.

Click the "Background Styles" button and select "Format Background." This will open the Format Background sidebar.

Adjust the background following the steps in the previous methods. Once the Format Background sidebar is open, you can adjust the background graphics using the steps outlined above. Use the "Picture or texture fill" option to set a new picture as the master background. This background will apply to every slide in your presentation.[4]
