Conversor.sh is a script programmed to convert pictures and images. Normally, digital cameras’ pictures can take lot of MB in every image, this script uses the convert program from the imagemagick packet and can reduce the space in more than 90%. Basically, the user will be able to change the picture dimensions, rotate the picture, change the picture quality, convert it into monochrome, etc, etc.

Conversor.sh can be downloaded from here
