Use EasyBatchPhoto to convert images from one format to another, compress and resize images. EasyBatchPhoto features Yellow Mug's signature easy-to-use interface. Just set the options and drop the images to process in the image well. EasyBatchPhoto is multi-threaded for fast, responsive operations. It also has a constant memory foot-print so you can dump hundreds on images on it, pop it into the background and continue to use your Mac while it works away in the background.
