PIL only supports up to Python 2.7, and as they don’t intend to advance with the development and Pillow is continuously updated, it is always recommended to use Pillow over PIL.Īnyway, implementation for users remains almost the same for both.īut be careful, because according to the official Pillow web, I can’t have both installed in your system at the same time.

The associated syntax is : from PIL import Image It also allows working with image formats and their associated orientations. This package provides a module named Image which is used to create and load new images into the environment. This package can be installed into the environment by using the following command : pip install Pillow This library provides extensive file format support, that is, it can be used to convert the images from one format to another. Python provides support for image processing using the PIL package (Python Imaging Library). Python provides various options to carry out the image conversion. However, both are interconvertible with respect to each other for usage and storage of media and pictures. Both the formats are used to provide good compatibilities with certain types of images like PNG works better with line drawings and icon graphics whereas JPG works well with photographs. PNG and JPG formats are used for image illustrations.
