    Pulverizr

    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!

    Pulverizr is completely written in JavaScript intended to run in a NodeJS environment. This means any idiot front-end developer such as myself can pick up the code and easily understand what's going on. Also, any normal developer could also pick it up and fix all the mistakes I made.

    Dependencies

    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
    

    On Ubuntu

    To install the dependencies on Ubuntu:

    apt-get install gifsicle libjpeg-progs optipng pngcrush
    

    On Windows

    Good luck to you, fine sir.

    Installation

    npm install -g pulverizr
    

    Usage

    Note: Be sure to test before you overwrite your images by using --dry-run

    Usage: pulverize [options] <file...>

    Options:
    
      -h, --help        output usage information
      -V, --version     output the version number
      -a, --aggressive  Uses more aggressive compression algorithms (takes longer, works better)
      --dry-run         Print summary but don't actually modify files
      -q, --quiet       Pulverizer will not report
      -R, --recursive   Recurse through directories
      -v, --verbose     Verbose mode
