Resizing changes the dimensions of an image (width and height) to fit specific requirements. Unlike cropping, which removes unwanted areas, resizing adjusts the entire image to new dimensions. Resizing is perfect for fitting images into specific spaces, preparing images for social media, and optimizing images for web use. When combined with aspect ratio lock, resizing maintains perfect proportions for professional-looking results without distortion.
