Kraken Web Optimizer!

ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It's useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization). ImageOptim removes EXIF meta­data, such as GPS position and camera's serial number, so that you can publish images without exposing private information (but there's an option to keep the meta­data if you need it).

Saving images for web/email/other media with the best compression ratio and quality is a difficult task if you don’t have the right tools.

Previewing the resulting image and the projected filesize will help the user choose the best settings. This kind of image optimization software is often called “Save for web”.
