Introduction

This maven plugin invokes OptiPNG on a set of images. OptiPNG is a PNG optimizer which reduces the file size of images by running a lossless recompression.

For sufficient performance of your build process, this plugin processes images in parallel.

Requirements

It is assumed that you have optipng installed on your system and that the executable is available within your $PATH.

This plugin has only been tested on Linux.
