ImageOptim-CLI

Automates batch optimisation of images.

Speeding up images often comes with a cost in picture quality and finding the right balance can be difficult.

Here we compare the percentage file size savings across several image optimisation tools, followed by the percentage of quality lost.

Here we display the file sizes and quality loss of a collection of images after they have been compressed by each respective tool.
