Clean up your layers on GIMP

Layers separate different “elements” when you’re editing an image on GIMP, Photoshop and other image-editing softwares. This helps you control the movement of each part of the images such as shadows, gradients, text and etc. When you create a layer, its size is the same as that of the image/canvas.

The wonderful thing about GIMP is that we can optimize its layers thus increasing control over the canvas. We can prevent useless area on a specific layer which enables users to know exactly the boundaries of each image.
