trimage

Tool for Losslessly Optimizing PNG and JPEG Files

Trimage is a cross-platform GUI and command-line interface to optimize image files via optipng, pngcrush, advpng and jpegoptim, depending on the filetype (currently, PNG and JPEG files are supported). It was inspired by imageoptim. All image files are losslessy compressed on the highest available compression levels. Trimage gives you various input functions to fit your own workflow: a regular file dialog, dragging and dropping and various command line options.
