}The Image Enlarger Tool allows users to increase the dimensions of an image by a specified scale factor. It features an option to enable high-quality smoothing to help maintain visual clarity during the enlargement process. This tool is useful for resizing small images for larger displays, preparing low-resolution graphics for print, or scaling up assets for web design projects.
