Basic Knowledge
What is Cropping?
Cropping is the process of removing unnecessary parts of an image and keeping only the required area. It is used to organize composition, emphasize the subject, and cut images to specified sizes.
What is Aspect Ratio?
Aspect ratio is the proportion of an image's width to height. Common ratios vary by use case: 16:9 (video/thumbnail), 1:1 (social media icon), and 4:3 (photograph). Cropping to match the aspect ratio of the destination prevents unintended cutoff caused by automatic cropping.
