Resizing changes the overall dimensions (width and height) of an image, scaling the entire image up or down. This is useful for making an image fit into a specific space, like a profile picture container or a website banner.

Cropping involves cutting out a portion of an image to change its composition or aspect ratio. This is useful for focusing on a specific subject, removing unwanted elements, or fitting an image into a different shape (e.g., from landscape to square).
