A little while ago I had mentioned PNGOptimizer – a great and simple to use PNG image optimizer software which really helps to cut down the file size of PNG images without any loss in image quality. Developer Voralent offers two of their own options to help webmasters optimize their website images.
PNGmini performs the same exact functions as PNGOptimizer, however while PNGOptimizer offers several options to allow you to choose what exactly you wish to have removed from your PNG image – PNGmini integrates a slider based optimization level selector allowing you to choose the level of optimization you want.
For those webmasters who find themselves working with JPG/JPEG images, Voralent has also released JPGmini, which applies similar lossless compression technology to crunch down your JPEGs. (No relation to the commercial JPEGmini, apparently. We predict Voralent will be hearing from them soon.)
The program looks and feels much like the PNG release. Drag and drop your images, click “Optimize”, and wait as the files are processed: it couldn’t be much easier.
