This program offers high-volume batch editing in a WYSIWYG image editor. The result is a highly scalable editor. Images in a batch can be processed simultaneously or individually, and you see all changes as you make them. No previewing is required because the "End Result" screen is always visible.
A slider bar lets you quickly choose from 127 compression levels to create images that download quickly. The image, file size, size savings and download time are updated dynamically as the compression level is changed. There is also a peek button to identify even the smallest compression quality losses.
