Pulverizr will smash your images down to size. It uses a number of free, and often times open source, programs to optimize and compress image files while still retaining their original appearance.
While modern image editor's, like Photoshop's, compressors do a decent job at cutting the extra fat around images, they sometimes leave behind extras you probably don't want or need. For example, EXIF data in JPEGs, color-correction data in PNGs and redundant frames in GIFs.
Pulverizr uses a handful of compressors to perform a number of lossless compression routines to squeeze every last bit out of your images (see Dependencies). Note this software isn't 100% stable yet. You may notice differences in images that may contain certain color profiles that can be stripped out by the compressors. Any strangeness you see, please report it!
If you're on Ubuntu, almost all of these dependencies can be retrieved using apt. Although Pulverizr works best with all its dependencies, it will gracefully fail when it doesn't find a compressor it's looking for.
The compressors Pulverizr uses are admittedly a bit obscure and sometimes difficult to install on all platforms.
On Mac OSX
If you're using homebrew, install the following packages:
brew install gifsicle libjpeg optipng pngcrush
To install the dependencies on Ubuntu:
apt-get install gifsicle libjpeg-progs optipng pngcrush
Good luck to you, fine sir.
npm install -g pulverizr
Note: Be sure to test before you overwrite your images by using
