Developers describe GraphicsMagick as "The swiss army knife of image processing". GraphicsMagick is the swiss army knife of image processing. Comprised of 267K physical lines (according to David A. Wheeler's SLOCCount) of source code in the base package (or 1,225K including 3rd party libraries) it provides a robust and efficient collection of tools and libraries which support reading, writing, and manipulating an image in over 88 major formats including important formats like DPX, GIF, JPEG, JPEG-2000, PNG, PDF, PNM, and TIFF. On the other hand, Thumbor is detailed as "Allows users to store and load images from anywhere needed". It is a smart imaging service. It enables on-demand crop, resizing and flipping of images. It allows users to store and load images from anywhere needed. It's really simple to implement a new loader or storage.
GraphicsMagick and Thumbor belong to "Image Processing and Management" category of the tech stack.
