Create an animated GIF in Keynote on Mac
You can create an animated GIF from slides in your presentation, then share it in a message or email, or post it on a website.
Create a GIF
Open the presentation, then choose File > Export To > Animated GIF (from the File menu at the top of your screen).
If you want to include other slides, enter the beginning and ending slide numbers.
Click the Resolution and Frame Rate pop-up menus and choose options.
Drag the Auto-advance slider to set how fast you want the animation to continue after a click.
Click Next, then type a name for the GIF.
Click the Where pop-up menu and choose where you want to save the file.
If the slide backgrounds use No Fill or have transparency, you can choose an option to use transparent backgrounds for your animated GIF.
