Resizing is essential for optimizing images for different uses, such as web display or printing. Maintaining the aspect ratio during resizing is crucial to prevent distortion.

17.2. Cropping

Cropping, on the other hand, involves removing portions of an image to change its composition or focus. Cropping does not change the resolution or DPI of the remaining image, but it reduces the overall pixel dimensions. Cropping is used to improve the visual appeal, remove unwanted elements, or adjust the framing of a photograph.

17.3. Key Differences

The primary difference is that resizing affects the size and resolution of the entire image, while cropping only changes its boundaries. Resizing is about scaling the image up or down, whereas cropping is about trimming away unwanted parts.

18. How Can Understanding Metadata Help Me Resize Photos?

Understanding metadata can significantly aid in resizing photos by providing crucial information about the image’s properties, such as dimensions, resolution, and file size. This information helps you make informed decisions about resizing and optimization.
