ImageMagick

ImageMagick is a free and open-source software suite for displaying, converting, and editing raster image files and vector image files. It supports a wide range of image formats, including JPEG, PNG, GIF, TIFF, and PDF, and can perform operations such as resizing, cropping, rotating, color correction, and adding special effects.

This tool is primarily used by developers, graphic designers, and photographers who need to automate image processing tasks or perform complex image manipulations. It is often integrated into web applications, content management systems, and other software to handle image uploads and transformations.
