Installation¶
Warnings¶
Warning
Pillow and PIL cannot co-exist in the same environment. Before installing Pillow, please uninstall PIL.
Warning
Pillow >= 1.0 no longer supports “import Image”. Please use “from PIL import Image” instead.
Warning
Pillow >= 2.1.0 no longer supports “import _imaging”. Please use “from PIL.Image import core as _imaging” instead.
Notes¶
Note
Pillow < 2.0.0 supports Python versions 2.4, 2.5, 2.6, 2.7.
Note
Pillow >= 2.0.0 < 4.0.0 supports Python versions 2.6, 2.7, 3.2, 3.3, 3.4, 3.5
Note
Pillow >= 4.0.0 supports Python versions 2.7, 3.3, 3.4, 3.5, 3.6
Basic Installation¶
Note
The following instructions will install Pillow with support for most common image formats. See External Libraries for a full list of external libraries supported.
Note
The basic installation works on Windows and macOS using the binaries from PyPI. Other installations require building from source as detailed below.
Install Pillow with pip:
$ pip install Pillow
Or use easy_install for installing Python Eggs as pip does not support them:
$ easy_install Pillow
Windows Installation¶
We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included:
> pip install Pillow
or:
> easy_install Pillow
macOS Installation¶
We provide binaries for macOS for each of the supported Python versions in the wheel format. These include support for all optional libraries except OpenJPEG:
$ pip install Pillow
Linux Installation¶
We do not provide binaries for Linux. 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.
FreeBSD Installation¶
Pillow can be installed on FreeBSD via the official Ports or Packages systems:
Ports:
$ cd /usr/ports/graphics/py-pillow && make install clean
Packages:
$ pkg install py27-pillow
Note
The Pillow FreeBSD port and packages are tested by the ports team with all supported FreeBSD versions and against Python 2.x and 3.x.
Building From Source¶
Download and extract the compressed archive from PyPI.
External Libraries¶
Note
You do not need to install all supported external libraries to use Pillow’s basic features. Zlib and libjpeg are required by default.
Note
There are scripts to install the dependencies for some operating
systems included in the depends
directory.
Many of Pillow’s features require external libraries:
- libjpeg provides JPEG functionality.
- Pillow has been tested with libjpeg versions 6b, 8, 9, 9a, and 9b 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.
- Starting with Pillow 3.0.0, zlib is required by default, but may
be disabled with the
- 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 2.7.
- 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 above 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.
- Pillow does not support the earlier 1.5 series which ships with Ubuntu and Debian.
- libimagequant provides improved color quantization
- Pillow has been tested with libimagequant 2.6.0
- Libimagequant is licensed GPLv3, which is more restrictive than the Pillow license, therefore we will not be distributing binaries with libimagequant support enabled.
- Windows support: Libimagequant requires VS2013/MSVC 18 to compile, so it is unlikely to work with any Python prior to 3.5 on Windows.
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 setup.py
or
setup.cfg
, or by adding environment variables on the command
line:
$ CFLAGS="-I/usr/pkg/include" pip install pillow
If Pillow has been previously built without the required
prerequisites, it may be necessary to manually clear the pip cache or
build without cache using the --no-cache-dir
option to force a
build with newly installed external libraries.
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. SettingMAX_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-imagequant
. 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
,--enable-imagequant
. 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. - Build flag:
--disable-platform-guessing
. Skips all of the platform dependent guessing of include and library directories for automated build systems that configure the proper paths in the environment variables (e.g. Buildroot). - Build flag:
--debug
. Adds a debugging flag to the include and library search process to dump all paths searched for and found to stdout.
Sample usage:
$ MAX_CONCURRENCY=1 python setup.py build_ext --enable-[feature] install
or using pip:
$ pip install pillow --global-option="build_ext" --global-option="--enable-[feature]"
Building on macOS¶
The Xcode command line tools are required to compile portions of
Pillow. The tools are installed by running xcode-select --install
from the command line. The command line tools are required even if you
have the full Xcode package installed. It may be necessary to run
sudo xcodebuild -license
to accept the license prior to using the
tools.
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
or from within the uncompressed source directory:
$ python setup.py install
Building on Windows¶
We don’t recommend trying to build on Windows. It is a maze of twisty
passages, mostly dead ends. There are build scripts and notes for the
Windows build in the winbuild
directory.
Building on FreeBSD¶
Note
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
Building on 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 dnf install python-devel redhat-rpm-config
Or for Python 3:
$ sudo dnf install python3-devel redhat-rpm-config
Note
redhat-rpm-config
is required on Fedora 23, but not earlier versions.
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:

libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python-tk
Prerequisites are installed on Fedora 23 with:
$ sudo dnf install libtiff-devel libjpeg-devel zlib-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, macOS, and Windows. Note that Android is not currently supported, but there have been reports of success.
