What is the purpose of cropping an image?

Cropping an image primarily serves the purpose of deleting unwanted parts of it. This technique allows designers and photographers to focus on the most significant elements within an image, thereby improving its composition and visual impact. By removing extraneous or distracting areas, cropping can help direct the viewer's attention to the key features of the image.

In graphic design and photography, ensuring that the essential elements are highlighted is crucial for conveying a clear message or aesthetic. This is particularly important in formats like advertising, where clarity is paramount. The act of cropping can also help adjust the framing and balance of the image, enhancing its overall appeal.

While enhancing color, changing resolution, and improving sharpness are all important aspects of image editing, they are different processes focused on altering the visual quality or technical specifications of an image rather than refining its composition by removing unwanted parts.
