Keynote for Mac: Add and edit images in Keynote
You can add photos and graphics from a photo library, or drag them from a website or from the Finder. You can crop an image by masking out parts you don’t want, and make adjustments to its background and exposure.
Add or replace an image
Do any of the following:
Drag an image from your computer or a webpage to a media placeholder or anywhere else on the slide or the workspace around it. (For more information about expanding your workspace, see Add workspace around a slide.)
Click in the bottom-right corner of a media placeholder, then select an image from a photo library.
Click in the toolbar, choose Photos, then drag an image from a photo library to the slide or to a media placeholder.
To search for an image, click the magnifying glass in the upper-right corner of the media window.
Select the image you want to replace, then in the Format sidebar, click the Image tab. Click Replace, then choose an image. The new image retains the dimensions of the original.
If you can’t replace an image on a slide, the image may be locked or grouped.
Add an image gallery
With an image gallery, you can view a collection of photos in one place on a slide, so only one shows at a time. When you play your presentation, you can cycle through the images before moving to the next slide. A visual effect plays during the transition from one image to the next.
Click in the toolbar, then choose Image Gallery.
Drag the image gallery to reposition it on the slide, and drag any selection handle to resize it.
To add images, drag them from your computer to the image gallery.
To customize the image gallery, make sure it’s still selected, then do any of the following:
Adjust the position or zoom level of an image: Double-click the image on the slide, then drag it to move it in the frame. Drag the slider to zoom.
Reorder images: In the Format sidebar, click the Gallery tab, then drag image thumbnails to reorder them.
Add an image caption: Double-click the text box below the image on the slide, then enter your text.
To use the same caption for all images, in the Format sidebar, click the Gallery tab, then select “Same caption for all images.” Double-click the text box below any image and enter your text.
To turn off captions, deselect Caption.
Change the transition between images: To change the visual effect that plays between images in your presentation, in the Animate sidebar, click the Action tab, then click Change.
Add an image description that can be used by assistive technology (for example, VoiceOver): Click the Gallery tab in the Format sidebar, then click an image thumbnail. Enter your text in the Image Description text box. The image description isn’t visible anywhere in your presentation.
To navigate through the image gallery, click or .
To remove an image from the gallery, in the Format sidebar, click the Gallery tab, click the image thumbnail, then press Delete.
Create a media placeholder
You can add a media placeholder (to which you can add an image, video, or audio file) to a presentation. Using a media placeholder lets you easily replace media without disturbing other elements on the slide.
Add an image to the slide, then format it how you want images to appear in the presentation.
You can add a mask, add a border, rotate the image, change its size, and more.
Select the image, then choose Format > Advanced > Define as Media Placeholder (from the Format menu at the top of your screen).
Take a photo or scan with an iOS device and add it to a presentation
If you have an iOS device nearby, you can use it to take a photo or scan and insert it directly into a presentation on your Mac.
Note: To make sure you can do this with your Mac and iOS device, see the Apple Support article System requirements for Continuity on Mac, iPhone, iPad, iPod touch, and Apple Watch.
On the slide where you want to add the photo or scan, click in the toolbar, then choose Take Photo or Scan Documents below your device name.
On your iOS device, do one of the following:
Take a photo: Tap , then tap Use Photo (tap Retake to retake the photo).
Scan a document automatically: Position the document in view to automatically capture the page, crop it, and correct its perspective. To insert the scan in your presentation, tap Save.
Scan a page manually: Tap , then drag the frame to adjust the area you want to scan. Tap Keep Scan, then tap Save.
Drag the image to move it, or drag any selection handle to resize it on your slide.
Note: If you scan more than one item, only the first one appears in your presentation.
Mask (crop) a photo
You can hide unwanted portions of an image without modifying the image file.
Double-click the image.
The mask controls appear. The default mask is the same size as your image.
Tip: To display the mask controls on a Mac with a Force Touch trackpad, force click the image (press firmly on the trackpad until you feel a deeper click).
Use the controls to frame just the parts of the image you want to be visible.
To mask an image with a shape, select the image, choose Format > Image > Mask With Shape, then choose a shape. Drag the handles on the shape to adjust its dimensions.
Remove background and other elements from a photo
Use the Instant Alpha tool to make parts of an image transparent. This feature is useful for removing an unwanted background or color from an image.
Select the image, then in the Format sidebar, click the Image tab.
Click Instant Alpha.
On the image, click the color you want to remove, then drag slowly over it.
As you drag, the selection grows to include areas that use similar colors. Click and drag multiple times to remove multiple colors.
Remove all instances of the color (even in other parts of the photo): Press the Option key while you drag.
Add colors back to an image: Press the Shift key while you drag.
Click Done, or click Reset to undo all your changes and restore the image to its original state.
Adjust exposure, saturation, and other image settings
Select the image, then in the Format sidebar, click the Image tab.
Use the controls to make adjustments.
Exposure: Changes the overall lightness or darkness of the image.
Saturation: Changes the richness of color in the image. Dragging to the right makes the colors richer or more vibrant.
Enhance: Automatically adjusts the image by spreading the red, green, and blue tones evenly across the histogram.
To revert your adjustments, click Reset, or click Reset Image in the Adjust Image window.
To see the image histogram and adjust more advanced features like contrast, highlights, shadows, sharpness, de-noise, temperature, and tint, click .
To restore the original settings, click Reset, or click Reset Image in the Adjust Image window.
You can open the Adjust Image controls in a separate window that you can move anywhere. Choose View > Show Adjust Image (from the View menu at the top of your screen).
Add an image description
You can add a description to any image in your presentation. Image descriptions are read by assistive technology (for example, VoiceOver) when somebody uses that technology to access your presentation. Image descriptions aren’t visible anywhere in your presentation.
Select the image, then, in the Format sidebar, click the Image tab.
Click the Description text box, then enter your text.
To add descriptions to the images in an image gallery, see “Add an image gallery,” above.
Tip: You can also add these buttons to the toolbar: Adjust Image, Instant Alpha, and Mask.
