Using the cropping tool
Wherever image files are supported, image thumbnails will feature a cropping icon in the top left when hovering over a thumbnail. Simply hover over the image thumbnail you wish to edit and click the crop tool icon to pull up the image editor. Make desired edits, and press Save.
When formatting an image in the dashboard, there are several options for editing:
Free-form cropping—including preset aspect ratios: 16:9, 4:3, and 1:1
Specify image dimensions in pixels
Zoom-in and zoom-out (enlarge and shrink?)
Rotate image 90° clockwise and counterclockwise
Flip image horizontally and vertically
