The Crop Shape tool lets you cut your photo into a specific shape, including square, circle, triangle, star, heart, and pentagon. The shapes let you crop your photo creatively, so you can make it more personal. For example, if you want a photo of you and your loved one, you can use the Heart shape crop tool to highlight you and your spouse within a heart.
Or, you could use a photo of your child and use the Star-shaped crop tool. Indeed, you can have fun with the Crop Shape tool.
If you want to keep it basic, you can crop the images normally by dragging the edges of the crop selector. Use the grid lines as your guide when cropping your photo.
Use the other crop tools as you see fit. If you want to remove the background to isolate your subject, you may use the Free-Hand tool, Quick Selection tool, or the Eraser tool.
