Google Slides and Drawings make it easy for you to tell a story and share your ideas. And a big part of storytelling is the images you use to bring a concept to life. Now it’s even easier to get those images just right, because now, Slides and Drawings will let you crop, apply shape masks, and add borders to your images right within your presentation.
Cropping
To crop an image, select it and click on the crop image icon in the toolbar.
Then drag the corners to your desired crop size and hit enter to make the crop.
Applying masks
To crop your image to a particular shape, apply a mask from the pull-down menu next to the crop icon.
There are tons of shapes, arrows and callout designs to choose from, like the heart example below.
Adding borders
Add a border to your image by clicking on the line weight icon, and give it a little extra pop by changing the line color.
Here’s to more beautiful presentations and drawings!
