Willow supports Python 2.7+ and 3.4+. It’s a pure-python library with no hard dependencies so doesn’t require a C compiler for a basic installation.

Installation using pip

pip install Willow

Installing underlying libraries

In order for most features of Willow to work, you need to install either Pillow or Wand.

Note that Pillow doesn’t support animated GIFs and Wand isn’t as fast. Installing both will give best results.
