Compressing Images in IrfanView

IrfanView is a multi-purpose tool. It takes screenshots, it crops them, resizes them, it can save them compressed, and you can do all of those at once by using the batch process. This will show you how to resize/compress images plus a quick guide on a small batch process. You should really check it out further since it can also crop images by specifying the x,y coordinates of an image to crop by.
