Here is a tutorial of how to Crop and Edit images within the Image Editor in WordPress.
Go to Media > Library and find the photo you need to edit.
Then under the image click the “Edit Image” button
Here you can change the scaling of the image to fit desired dimensions.
You can crop an image by Clicking and Dragging your mouse over the part of the image you want and hitting the Crop button on top. Here you can also Rotate and Flip the image if needed.
Now you can save the Cropped image and it will automatically resize or if you’re not happy with the cropping, you can click Cancel and the image will revert back to normal.
