ImageOptim

ImageOptim is a front-end (GUI) for set of tools for optimisation of PNG and JPEG images.

Optimisation makes files smaller (in terms of disk space) by finding optimal compression parameters and by removing unneccessary information, like file comments, EXIF tags and color profiles.

• Fix for erroneous claim that files have already been optimized
• Faster default settings for Macbook Air and older Macs
• Fixed QuickLook animation on OS X 10.10 Yosemite
• Gratuitous translucency in OS X 10.10 Yosemite
• Updated translations and fixed help files
• Improved drag'n'drop of files outside ImageOptim window
