Reduce photo file size by up to 5x, without compromising quality

pngquant is a command-line utility and a library for converting 24/32-bit PNG images to paletted (8-bit) PNGs. The conversion reduces file sizes significantly (often as much as 70%) and preserves full alpha transparency. Generated images are compatible with all modern web browsers, and have better fallback in IE6 than 24-bit PNGs.

Trimage is a cross-platform GUI and command-line interface to optimize image files for websites, using 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, and EXIF and other metadata is removed. Trimage gives you various input functions to fit your own workflow: A regular file dialog, dragging and dropping and various command line options.

Advanced lossy compression for PNG images that preserves full alpha transparency.

"ShrinkIt is a simple, small tool (for Mac OS X Snow Leopard) that will automate the process of stripping needless metadata from PDFs by re-saving them using Apple’s PDF processor"

"ImageOptim is a front-end (GUI) for set of tools for optimisation of PNG/JPEG images and GIF animations. Optimisation makes files smaller (in terms of disk space) by finding optimal compression parameters and by removing unneccessary information, like file comments, EXIF tags and color profiles."
