Image Optim is a free application/tool for Mac system to optimize images. If you don't have a Mac, I also have a basic web interface that works on any platform. I wrote a GUI for all image optimization tools I could find, including MozJPEG and jpegoptim that optimize Huffman tables, progressive scans, and (optionally) remove invisible metadata. In addition, it works as a batch photo renamer that helps you save the new files with names different from those of the original files. The tool may remove information you want to keep, like copyright information.PhotoResize Pro is an image optimization tool that lets you resize, convert, and adjust the quality of multiple photos at once.Allows you to compress JPEG images and PNG formats.Offers compression functionalities for high density or ‘Retina' displays.Their web service offers high-quality images compressed for mobile or desktop resolutions.Has lossy and lossless compression options.
