Pillow and PIL cannot co-exist in the same environment. Before installing Pillow, please uninstall PIL.


Pillow >= 1.0 no longer supports “import Image”. Please use “from PIL import Image” instead.


Pillow >= 2.1.0 no longer supports “import _imaging”. Please use “from PIL.Image import core as _imaging” instead.



Pillow < 2.0.0 supports Python versions 2.4, 2.5, 2.6, 2.7.


Pillow >= 2.0.0 supports Python versions 2.6, 2.7, 3.2, 3.3, 3.4, 3.5

Basic Installation


The following instructions will install Pillow with support for most common image formats. See External Libraries for a full list of external libraries supported.

Install Pillow with pip:

$ pip install Pillow

Or use easy_install for installing Python Eggs as pip does not support them:

$ easy_install Pillow

Or download and extract the compressed archive from PyPI and inside it run:

$ python install

External Libraries


You do not need to install all external libraries supported to use Pillow’s basic features.

Many of Pillow’s features require external libraries:

  • libjpeg provides JPEG functionality.
    • Pillow has been tested with libjpeg versions 6b, 8, and 9 and libjpeg-turbo version 8.
    • Starting with Pillow 3.0.0, libjpeg is required by default, but may be disabled with the --disable-jpeg flag.
  • zlib provides access to compressed PNGs
    • Starting with Pillow 3.0.0, zlib is required by default, but may be disabled with the --disable-zlib flag.
  • libtiff provides compressed TIFF functionality
    • Pillow has been tested with libtiff versions 3.x and 4.0
  • libfreetype provides type related services
  • littlecms provides color management
    • Pillow version 2.2.1 and below uses liblcms1, Pillow 2.3.0 and above uses liblcms2. Tested with 1.19 and 2.2.
  • libwebp provides the WebP format.
    • Pillow has been tested with version 0.1.3, which does not read transparent WebP files. Versions 0.3.0 and 0.4.0 support transparency.
  • tcl/tk provides support for tkinter bitmap and photo images.
  • openjpeg provides JPEG 2000 functionality.
    • Pillow has been tested with openjpeg 2.0.0 and 2.1.0.

Once you have installed the prerequisites,run:

$ pip install Pillow

If the prerequisites are installed in the standard library locations for your machine (e.g. /usr or /usr/local), no additional configuration should be required. If they are installed in a non-standard location, you may need to configure setuptools to use those locations by editing or setup.cfg, or by adding environment variables on the command line:

$ CFLAGS="-I/usr/pkg/include" pip install pillow

Build Options

  • Environment Variable: MAX_CONCURRENCY=n. By default, Pillow will use multiprocessing to build the extension on all available CPUs, but not more than 4. Setting MAX_CONCURRENCY to 1 will disable parallel building.
  • Build flags: --disable-zlib, --disable-jpeg, --disable-tiff, --disable-freetype, --disable-tcl, --disable-tk, --disable-lcms, --disable-webp, --disable-webpmux, --disable-jpeg2000. Disable building the corresponding feature even if the development libraries are present on the building machine.
  • Build flags: --enable-zlib, --enable-jpeg, --enable-tiff, --enable-freetype, --enable-tcl, --enable-tk, --enable-lcms, --enable-webp, --enable-webpmux, --enable-jpeg2000. Require that the corresponding feature is built. The build will raise an exception if the libraries are not found. Webpmux (WebP metadata) relies on WebP support. Tcl and Tk also must be used together.

Sample Usage:

$ MAX_CONCURRENCY=1 python build_ext --enable-[feature] install

OS X Installation

We provide binaries for OS X in the form of Python Wheels. Alternatively you can compile Pillow from soure with XCode.

The easiest way to install external libraries is via Homebrew. After you install Homebrew, run:

$ brew install libtiff libjpeg webp little-cms2

Install Pillow with:

$ pip install Pillow

Windows Installation

We provide binaries for Windows in the form of Python Eggs and Python Wheels:

Python Eggs


pip does not support Python Eggs; use easy_install instead.

$ easy_install Pillow

Python Wheels


Requires setuptools >=0.8 and pip >=1.4.1. Some older versions of pip required the --use-wheel flag.

$ pip install Pillow

If the above does not work, it’s likely because we haven’t uploaded a wheel for the latest version of Pillow. In that case, try pinning it to a specific version:

$ pip install Pillow==2.6.1

FreeBSD Installation


Only FreeBSD 10 tested

Make sure you have Python’s development libraries installed.:

$ sudo pkg install python2

Or for Python 3:

$ sudo pkg install python3

Prerequisites are installed on FreeBSD 10 with:

$ sudo pkg install jpeg tiff webp lcms2 freetype2

Linux Installation


Most major Linux distributions, including Fedora, Debian/Ubuntu and ArchLinux include Pillow in packages that previously contained PIL e.g. python-imaging. Please consider using native operating system packages first to avoid installation problems and/or missing library support later.

We do not provide binaries for Linux. If you didn’t build Python from source, make sure you have Python’s development libraries installed. In Debian or Ubuntu:

$ sudo apt-get install python-dev python-setuptools

Or for Python 3:

$ sudo apt-get install python3-dev python3-setuptools

In Fedora, the command is:

$ sudo yum install python-devel

Prerequisites are installed on Ubuntu 12.04 LTS or Raspian Wheezy 7.0 with:

$ sudo apt-get install libtiff4-dev libjpeg8-dev zlib1g-dev \
    libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk

Prerequisites are installed on Ubuntu 14.04 LTS with:

$ sudo apt-get install libtiff5-dev libjpeg8-dev zlib1g-dev \
    libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk

Prerequisites are installed on Fedora 20 with:

$ sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
    lcms2-devel libwebp-devel tcl-devel tk-devel

Platform Support

Current platform support for Pillow. Binary distributions are contributed for each release on a volunteer basis, but the source should compile and run everywhere platform support is listed. In general, we aim to support all current versions of Linux, OS X, and Windows.


Contributors please test Pillow on your platform then update this document and send a pull request.
