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 JPG 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.
