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.

See the installation guide, examples and grunt-imageoptim.
