## What it is
Pillow is the actively maintained fork of the Python Imaging Library (PIL), providing image opening, editing, and saving across many file formats with a simple Python API. It is a foundational dependency used by millions of Python projects and packages for image processing tasks.

## Use cases
- resize and crop images in python
- convert images between png jpeg webp formats
- generate thumbnails for uploaded images
- draw text and shapes on images
- read image metadata and exif data
- process images in a django web app

## When to choose
- you need to open, manipulate, or save images in Python
- you want a mature, widely supported imaging library with broad format support
- you need thumbnails, resizing, or format conversion in web backends

## When to avoid
- you need GPU-accelerated or deep-learning-based image processing
- you are working outside Python
- you need advanced computer vision like object detection

## Facets
- artifact type: library
- maturity: stable
- function: image-processing
- domain: image-processing, files, web-development
- platform: python, cross-platform, windows
- tags: pil, imaging, image-formats, thumbnails, python-library, linux, macos
