Announcing IMGCrush 0.4.0 and IMGCrush_GUI 0.4.0 , a new release bringing new features and bugfixes, as well as considerable speedup (even though it's still quite slow) IMGCrush is an image compressor capable of compressing files to user specified size or quality using common web image formats particularly well suited to optimize images for web sites. IMGCrush_GUI is a simple Tkinter GUI using basic subset of IMGCrush options. It should be replaced by a more advanced GTK or Qt GUI in future.
