Compressing images from the CLI

Easy script using imagemagick to compress images from the terminal

Steps

• Move all your image files to a folder

• calculate it's folder size using du

• create a copy of the folder.

• install imagemagick

brew install imagemagick

• in this folder, perform the following actions:

mkdir compressed
for i in *; do convert $i -resize 40% compressed/$i; done;

The above will compress all images by making the size 40% of the initial size and will move it to a folder called compressed

• Check folder structure again using du

• if it's still too much, repeat again but this time reduce quality to even lower
