The Crop Tool is used to crop or clip an image or layer. This tool is most used to remove borders, or to eliminate unwanted areas to provide you with a more focussed working area. It is also useful when wanting specific image sizes such as for desktop wallpapers.
The Crop Tool can be called in the following order, from the image-menu:

The Tool can also be called by clicking the tool icon:

Options
The available tool options for Crop can be accessed by
double clicking the Crop tool icon.
The Tool Toggle for the Crop Tool alternates between Crop mode and Resize mode.
Crop Mode is the standard mode of operation for the Crop Tool. Cropping an image or layer will change a layer by eliminating everything outside the cropping area. The cropping area can be set by either dragging the tool to form a rectangle area or manually setting the origin, width, and height. Cropping areas can also be set based on an existing selection or by using the Auto Shrink button. These options are available within the Crop And Resize Information dialog which is shown when the Crop Tool is clicked on an image or layer.
Resize Mode works in a similar fashion to Crop Mode with the exception that the layer or layers affected by the cropping are not changed in size. That is to say that the layer size remains as it is, but the pixel information outside the cropping region is removed.
This option will make the crop or resize affect only the active layer.
This option allows the crop or resize to take place outside the image or layer boundary.
