ImageMagick – Alternatives to RIOT for Mac
This article I introduce you an alternative software to Riot (is one of my favorite image optimizer tool, but it only supports for Windows).
ImageMagick is a freeware that allows you to create, edit, and compose bitmap images. ImageMagick can read, convert and write images in a variety of formats such as: GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF… (about 100).
ImageMagick is delivered as a ready-to-run binary distribution or as source code that you may use, copy, modify, and distribute in both open and proprietary applications.
