Python Imaging Library
Library for the Python programming language

Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7.

Development of the original project, known as PIL, was discontinued in 2011. Subsequently, a successor project named Pillow forked the PIL repository and added Python 3.x support. This fork has been adopted as a replacement for the original PIL in Linux distributions including Debian and Ubuntu (since 13.04).

Capabilities

PIL offers several standard procedures for image manipulation. These include:

  • per-pixel manipulations,6
  • masking and transparency handling,
  • image filtering, such as blurring, contouring, smoothing, or edge finding,7
  • image enhancing, such as sharpening, adjusting brightness, contrast or color,8
  • adding text

File formats

Supported file formats include PPM, PNG, JPEG, GIF, TIFF, and BMP. PIL is extensible, allowing users to create custom decoders for any file format.9

Programming examples

import os from PIL import Image def convert_jpegs_to_pngs(folder_path): # Checks if the provided path is a folder if not os.path.isdir(folder_path): print(f"Error: {folder_path} is not a valid folder.") return # Iterates over all files in the folder for filename in os.listdir(folder_path): # Checks if the file has a .jpg or .jpeg extension if filename.lower().endswith(".jpg") or filename.lower().endswith(".jpeg"): # Full path of the file jpeg_path = os.path.join(folder_path, filename) # Path for the converted file png_path = os.path.join(folder_path, os.path.splitext(filename)[0] + ".png") try: # Opens the JPEG image with Image.open(jpeg_path) as img: # Converts and saves as PNG img.save(png_path, "PNG") print(f"Converted {jpeg_path} to {png_path}") except Exception as e: print(f"Error converting {jpeg_path}: {e}")
