Change a slide background in Keynote on Mac
You can change the background color or image of individual slides in a presentation. You can also use a dynamic background that uses ambient animations to add movement to a slide.
Use a color, gradient, or image as a slide background
To change the slide background, click , click the Standard button in the Background controls, then do one of the following:
Use a color designed to match your theme: Click the color well next to Current Fill, then select a color.
Use any color: Click the pop-up menu and choose Color Fill, then click the color wheel to open the Color Fill window, where you can choose any color.
Use a two-color gradient fill: Click the pop-up menu and choose Gradient Fill, then use the color controls to choose colors. Click the left side of each color well to open a palette of colors that match the theme; click the color wheel on the right to open the Colors window, where you can choose any color.
Use a custom gradient: Click the pop-up menu and choose Advanced Gradient Fill, then click the color stops below the fill bar to choose colors. You can drag the color stops and use the other controls to change the blend, angle, and direction of the gradient.
Use an image: Click the pop-up menu and choose Image Fill, or choose Advanced Image Fill if you want to add a tint to the image. Click Choose, navigate to your photos, then double-click an image to add it. To change how the image fills the background, click the pop-up menu above the Choose button, then choose an option:
Original Size: Places the image without altering the image’s original dimensions. To resize the image, drag the Scale slider.
Stretch: Resizes the image to fit the slide’s dimensions, which might change the image’s proportions.
Tile: Repeats the image on the slide. To resize the image, drag the Scale slider.
Scale to Fill: Makes the image larger or smaller to leave no space around the image.
Scale to Fit: Resizes the image to fit the slide’s dimensions, but maintains the image’s proportions.
If you chose Advanced Image Fill, click the color well or color wheel to select a tint color. Adding a tint makes the image more transparent.
Use a dynamic background that moves
Dynamic backgrounds are procedurally generated animations that add motion to slides without significantly increasing the size of your Keynote file. There are a variety of preset dynamic background styles you can choose and customize. If you use the same dynamic background style on more than one consecutive slide, the animation plays seamlessly when you change slides. You can save a custom dynamic background style so you can use it again later.
Tip: Use the Magic Move slide transition to seamlessly move between slides that use the same dynamic background style but with different appearance settings.
To add a dynamic background to the selected slide or slides, click , click the Dynamic button in the Background controls, then click the background style you want to use.
Click or to see more styles.
Do any of the following:
Select a different dynamic background: Click another style from the options below the Dynamic button.
Pause the dynamic background while you work: Turn off Preview Motion. The dynamic background still moves when you play the slideshow.
Change the color of the dynamic background: Click a color stop beneath the Color slider, then choose any color in the window. You can also slide a color stop to adjust how the colors are blended together. To delete a color stop, drag it away from the slider.
Customize a dynamic background style: Each dynamic background style has its own unique animation and appearance options you can change. To customize these options, such as the dynamic background’s speed, the distance between waves, or how blurry the background appears, use the controls at the bottom of the sidebar.
Save a custom dynamic background style: You can save any formatting you make to a dynamic background style so you can easily reuse it in your presentation. To save a custom style, click or next to the style thumbnails, then click .
When you change the background of a slide layout, it is applied to every slide that uses that layout.
