In this tutorial we will learn how to use pngquant to reduce the size of .png images in Linux. Especially useful for those we need to place on a website or in a PlayStation game.

Let's get started:

1. The first thing to do is to download the utility from Pngquant.org/releases.html. Open a terminal, go to the directory where the file is and type our first command:

sudo dpkg -i pngquant_version_del_archivo.deb

1. This command will create a folder "pornel-pngquant-version_of_the_file". We go inside it and type to install the utility:

sudo make install

1. Once installed, to use it you have to go to the folder where the image is and type:

pngquant nombre_de_la_imagen.png

1. If there are several images in the folder we can use:

pngquant *.png

Pngquant will create the optimised files with the file name ending "-fs8.png", leaving the originals intact. For more options, you can visit Pngquant.org or the Github.com/pornel/pngquant page.
