> [Optipng|http://optipng.sourceforge.net/] is a utility that tweaks compression parameters in png files to reduce their size without losing quality.  Running this on all the png resources in NiFi reduces their total size by about 35% (12M -> 7.4M).
> This isn't a huge change but it should be very low impact and will hopefully make the ui feel a bit snappier with smaller resources.
> [Command to optimize all pngs|http://stackoverflow.com/questions/21801085/optimize-images-in-directory-using-multiple-cpu-cores#answer-21998589]:
