You can remove animation effects that you previously applied to text or objects (such as pictures, shapes, SmartArt graphics, etc.)
If you're looking for information on removing a transition effect from an entire slide, see Add, change, or remove transitions between slides.
Remove one animation effect
On the Animation tab, click Animation Pane.
On the slide, click the animated object that you want to remove the effect from.
Tip: All of the effects applied to that object are highlighted in the Animation Pane.
In the Animation Pane, click the effect to remove, click the down arrow, and then click Remove.
Remove more than one or all animation effects
To remove more than one animation effect from text or an object, in the Animation Pane, press Ctrl, click each animation effect that you want to remove, and then press Delete.
To remove all animation effects from text or an object, click the object that you want to stop animating. Then, on the Animations tab, in the gallery of animation effects, click None.
Disable all animations in a presentation
Although you can't remove all animations from an entire presentation in one step (you have to remove animations from each object individually, as described above), you can disable all animations in your presentation.
On the Slide Show tab, click Set Up Slide Show.
Under Show options, select Show without animation.
