Prior to Pillow 2.0.0, very few image code changes were made. Pillow 2.0.0
added Python 3 support and includes many bug fixes from many contributors.
As more time passes since the last PIL release (1.1.7 in 2009), the likelihood of a new PIL release decreases. However, we've yet to hear an official "PIL is dead" announcement.
The last PIL release was in 2009 (1.1.7) and `no future releases are expected <https://github.com/python-pillow/Pillow/issues/1535>`_. In January 2020, `the PyPI moderators exhausted the PEP 541 process for contacting the PIL project owner <https://github.com/python-pillow/Pillow/issues/1535#issuecomment-570308446>`_ and the `PIL project on PyPI <https://pypi.org/project/PIL>`_ was transferred to the `Pillow team <https://github.com/python-pillow/Pillow/graphs/contributors>`_. The Pillow team has no plans to update the PIL project on PyPI.

Basic Installation
------------------
.. note::
.. Note:: This section has moved to :ref:`basic-installation`. Please update references accordingly.
The following instructions will install Pillow with support for
most common image formats. See :ref:`external-libraries` for a
full list of external libraries supported.
Python Support
--------------
Install Pillow with :command:`pip`::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
Optionally, install :pypi:`defusedxml` for Pillow to read XMP data,
and :pypi:`olefile` for Pillow to read FPX and MIC images::
python3 -m pip install --upgrade defusedxml olefile
.. tab:: Linux
We provide binaries for Linux for each of the supported Python
versions in the manylinux wheel format. These include support for all
optional libraries except libimagequant. Raqm support requires
FriBiDi to be installed separately::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
Most major Linux distributions, including Fedora, Ubuntu and ArchLinux
also include Pillow in packages that previously contained PIL e.g.
``python-imaging``. Debian splits it into two packages, ``python3-pil``
and ``python3-pil.imagetk``.
.. tab:: macOS
We provide binaries for macOS for each of the supported Python
versions in the wheel format. These include support for all optional
libraries except libimagequant. Raqm support requires
FriBiDi to be installed separately::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
While we provide binaries for both x86-64 and arm64, we do not provide universal2
binaries. However, it is simple to combine our current binaries to create one::
python3 -m pip download --only-binary=:all: --platform macosx_10_10_x86_64 Pillow
python3 -m pip download --only-binary=:all: --platform macosx_11_0_arm64 Pillow
python3 -m pip install delocate
Then, with the names of the downloaded wheels, use Python to combine them::
from delocate.fuse import fuse_wheels
fuse_wheels('Pillow-9.4.0-2-cp39-cp39-macosx_10_10_x86_64.whl', 'Pillow-9.4.0-cp39-cp39-macosx_11_0_arm64.whl', 'Pillow-9.4.0-cp39-cp39-macosx_11_0_universal2.whl')
.. tab:: Windows
We provide Pillow binaries for Windows compiled for the matrix of supported
Pythons in the wheel format. These include x86, x86-64 and arm64 versions
(with the exception of Python 3.8 on arm64). These binaries include support
for all optional libraries except libimagequant and libxcb. Raqm support
requires FriBiDi to be installed separately::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
To install Pillow in MSYS2, see `Building on Windows using MSYS2/MinGW`_.
.. tab:: FreeBSD
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 py38-pillow
.. note::
The `Pillow FreeBSD port
<https://www.freshports.org/graphics/py-pillow/>`_ and packages
are tested by the ports team with all supported FreeBSD versions.

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 Dockerfiles in our `Docker images repo
<https://github.com/python-pillow/docker-images>`_ to install the
dependencies for some operating systems.
Many of Pillow's features require external libraries:
* **libjpeg** provides JPEG functionality.
* Pillow has been tested with libjpeg versions **6b**, **8**, **9-9d** and
libjpeg-turbo version **8**.
* Starting with Pillow 3.0.0, libjpeg is required by default. It can be
disabled with the ``-C jpeg=disable`` flag.
* **zlib** provides access to compressed PNGs
* Starting with Pillow 3.0.0, zlib is required by default. It can be
disabled with the ``-C zlib=disable`` flag.
* **libtiff** provides compressed TIFF functionality
* Pillow has been tested with libtiff versions **3.x** and **4.0-4.6.0**
* **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 **2.7-2.16**.
* **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.
* **openjpeg** provides JPEG 2000 functionality.
* Pillow has been tested with openjpeg **2.0.0**, **2.1.0**, **2.3.1**,
**2.4.0**, **2.5.0** and **2.5.2**.
* Pillow does **not** support the earlier **1.5** series which ships
with Debian Jessie.
* **libimagequant** provides improved color quantization
* Pillow has been tested with libimagequant **2.6-4.2.2**
* Libimagequant is licensed GPLv3, which is more restrictive than
the Pillow license, therefore we will not be distributing binaries
with libimagequant support enabled.
* **libraqm** provides complex text layout support.
* libraqm provides bidirectional text support (using FriBiDi),
shaping (using HarfBuzz), and proper script itemization. As a
result, Raqm can support most writing systems covered by Unicode.
* libraqm depends on the following libraries: FreeType, HarfBuzz,
FriBiDi, make sure that you install them before installing libraqm
if not available as package in your system.
* Setting text direction or font features is not supported without libraqm.
* Pillow wheels since version 8.2.0 include a modified version of libraqm that
loads libfribidi at runtime if it is installed.
On Windows this requires compiling FriBiDi and installing ``fribidi.dll``
into a directory listed in the `Dynamic-link library search order (Microsoft Learn)
<https://learn.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-search-order#search-order-for-unpackaged-apps>`_
(``fribidi-0.dll`` or ``libfribidi-0.dll`` are also detected).
See `Build Options`_ to see how to build this version.
* Previous versions of Pillow (5.0.0 to 8.1.2) linked libraqm dynamically at runtime.
* **libxcb** provides X11 screengrab support.
.. tab:: 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 python3-dev python3-setuptools
In Fedora, the command is::
sudo dnf install python3-devel redhat-rpm-config
In Alpine, the command is::
sudo apk add python3-dev py3-setuptools
.. Note:: ``redhat-rpm-config`` is required on Fedora 23, but not earlier versions.
Prerequisites for **Ubuntu 16.04 LTS - 22.04 LTS** are installed with::
sudo apt-get install libtiff5-dev libjpeg8-dev libopenjp2-7-dev zlib1g-dev \
libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python3-tk \
libharfbuzz-dev libfribidi-dev libxcb1-dev
To install libraqm, ``sudo apt-get install meson`` and then see
``depends/install_raqm.sh``.
Prerequisites are installed on recent **Red Hat**, **CentOS** or **Fedora** with::
sudo dnf install libtiff-devel libjpeg-devel openjpeg2-devel zlib-devel \
freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel \
harfbuzz-devel fribidi-devel libraqm-devel libimagequant-devel libxcb-devel
Note that the package manager may be yum or DNF, depending on the
exact distribution.
Prerequisites are installed for **Alpine** with::
sudo apk add tiff-dev jpeg-dev openjpeg-dev zlib-dev freetype-dev lcms2-dev \
libwebp-dev tcl-dev tk-dev harfbuzz-dev fribidi-dev libimagequant-dev \
libxcb-dev libpng-dev
See also the ``Dockerfile``\s in the Test Infrastructure repo
(https://github.com/python-pillow/docker-images) for a known working
install process for other tested distros.
.. tab:: 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
<https://brew.sh/>`_. After you install Homebrew, run::
brew install libjpeg libtiff little-cms2 openjpeg webp
To install libraqm on macOS use Homebrew to install its dependencies::
brew install freetype harfbuzz fribidi
Then see ``depends/install_raqm_cmake.sh`` to install libraqm.
.. tab:: Windows
We recommend you use prebuilt wheels from PyPI.
If you wish to compile Pillow manually, you can use the build scripts
in the ``winbuild`` directory used for CI testing and development.
These scripts require Visual Studio 2017 or newer and NASM.
The scripts also install Pillow from the local copy of the source code, so the
`Installing`_ instructions will not be necessary afterwards.
.. tab:: Windows using MSYS2/MinGW
To build Pillow using MSYS2, make sure you run the **MSYS2 MinGW 32-bit** or
**MSYS2 MinGW 64-bit** console, *not* **MSYS2** directly.
The following instructions target the 64-bit build, for 32-bit
replace all occurrences of ``mingw-w64-x86_64-`` with ``mingw-w64-i686-``.
Make sure you have Python and GCC installed::
pacman -S \
mingw-w64-x86_64-gcc \
mingw-w64-x86_64-python3 \
mingw-w64-x86_64-python3-pip \
mingw-w64-x86_64-python3-setuptools
Prerequisites are installed on **MSYS2 MinGW 64-bit** with::
pacman -S \
mingw-w64-x86_64-libjpeg-turbo \
mingw-w64-x86_64-zlib \
mingw-w64-x86_64-libtiff \
mingw-w64-x86_64-freetype \
mingw-w64-x86_64-lcms2 \
mingw-w64-x86_64-libwebp \
mingw-w64-x86_64-openjpeg2 \
mingw-w64-x86_64-libimagequant \
mingw-w64-x86_64-libraqm
https://www.msys2.org/docs/python/ states that setuptools >= 60 does not work with
MSYS2. To workaround this, before installing Pillow you must run::
export SETUPTOOLS_USE_DISTUTILS=stdlib
.. tab:: FreeBSD
.. Note:: Only FreeBSD 10 and 11 tested
Make sure you have Python's development libraries installed::
sudo pkg install python3
Prerequisites are installed on **FreeBSD 10 or 11** with::
sudo pkg install jpeg-turbo tiff webp lcms2 freetype2 openjpeg harfbuzz fribidi libxcb
Then see ``depends/install_raqm_cmake.sh`` to install libraqm.
.. tab:: Android
Basic Android support has been added for compilation within the Termux
environment. The dependencies can be installed by::
pkg install -y python ndk-sysroot clang make \
libjpeg-turbo
This has been tested within the Termux app on ChromeOS, on x86.
Installing
^^^^^^^^^^
Once you have installed the prerequisites, to install Pillow from the source
code on PyPI, run::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow --no-binary :all:
If the prerequisites are installed in the standard library locations
for your machine (e.g. :file:`/usr` or :file:`/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 :file:`setup.py` or
:file:`pyproject.toml`, or by adding environment variables on the command
line::
CFLAGS="-I/usr/pkg/include" python3 -m pip install --upgrade Pillow --no-binary :all:
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.
If you would like to install from a local copy of the source code instead, you
can clone from GitHub with ``git clone https://github.com/python-pillow/Pillow``
or download and extract the `compressed archive from PyPI`_.
After navigating to the Pillow directory, run::
python3 -m pip install --upgrade pip
python3 -m pip install .
.. _compressed archive from PyPI: https://pypi.org/project/pillow/#files
Build Options
"""""""""""""
* Environment variable: ``MAX_CONCURRENCY=n``. Pillow can use
multiprocessing to build the extension. Setting ``MAX_CONCURRENCY``
sets the number of CPUs to use, or can disable parallel building by
using a setting of 1. By default, it uses 4 CPUs, or if 4 are not
available, as many as are present.
* Config settings: ``-C zlib=disable``, ``-C jpeg=disable``,
``-C tiff=disable``, ``-C freetype=disable``, ``-C raqm=disable``,
``-C lcms=disable``, ``-C webp=disable``, ``-C webpmux=disable``,
``-C jpeg2000=disable``, ``-C imagequant=disable``, ``-C xcb=disable``.
Disable building the corresponding feature even if the development
libraries are present on the building machine.
* Config settings: ``-C zlib=enable``, ``-C jpeg=enable``,
``-C tiff=enable``, ``-C freetype=enable``, ``-C raqm=enable``,
``-C lcms=enable``, ``-C webp=enable``, ``-C webpmux=enable``,
``-C jpeg2000=enable``, ``-C imagequant=enable``, ``-C xcb=enable``.
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.
* Config settings: ``-C raqm=vendor``, ``-C fribidi=vendor``.
These flags are used to compile a modified version of libraqm and
a shim that dynamically loads libfribidi at runtime. These are
used to compile the standard Pillow wheels. Compiling libraqm requires
a C99-compliant compiler.
* Build flag: ``-C platform-guessing=disable``. 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: ``-C debug=true``. Adds a debugging flag to the include and
library search process to dump all paths searched for and found to
stdout.
Sample usage::
python3 -m pip install --upgrade Pillow -C [feature]=enable

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.

Basic Installation
==================
.. note::
The following instructions will install Pillow with support for
most common image formats. See :ref:`external-libraries` for a
full list of external libraries supported.
Install Pillow with :command:`pip`::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
Optionally, install :pypi:`defusedxml` for Pillow to read XMP data,
and :pypi:`olefile` for Pillow to read FPX and MIC images::
python3 -m pip install --upgrade defusedxml olefile
.. tab:: Linux
We provide binaries for Linux for each of the supported Python
versions in the manylinux wheel format. These include support for all
optional libraries except libimagequant. Raqm support requires
FriBiDi to be installed separately::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
Most major Linux distributions, including Fedora, Ubuntu and ArchLinux
also include Pillow in packages that previously contained PIL e.g.
``python-imaging``. Debian splits it into two packages, ``python3-pil``
and ``python3-pil.imagetk``.
.. tab:: macOS
We provide binaries for macOS for each of the supported Python
versions in the wheel format. These include support for all optional
libraries except libimagequant. Raqm support requires
FriBiDi to be installed separately::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
While we provide binaries for both x86-64 and arm64, we do not provide universal2
binaries. However, it is simple to combine our current binaries to create one::
python3 -m pip download --only-binary=:all: --platform macosx_10_10_x86_64 Pillow
python3 -m pip download --only-binary=:all: --platform macosx_11_0_arm64 Pillow
python3 -m pip install delocate
Then, with the names of the downloaded wheels, use Python to combine them::
from delocate.fuse import fuse_wheels
fuse_wheels('Pillow-9.4.0-2-cp39-cp39-macosx_10_10_x86_64.whl', 'Pillow-9.4.0-cp39-cp39-macosx_11_0_arm64.whl', 'Pillow-9.4.0-cp39-cp39-macosx_11_0_universal2.whl')
.. tab:: Windows
We provide Pillow binaries for Windows compiled for the matrix of supported
Pythons in the wheel format. These include x86, x86-64 and arm64 versions
(with the exception of Python 3.8 on arm64). These binaries include support
for all optional libraries except libimagequant and libxcb. Raqm support
requires FriBiDi to be installed separately::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
To install Pillow in MSYS2, see :ref:`building-from-source`.
.. tab:: FreeBSD
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 py38-pillow
.. note::
The `Pillow FreeBSD port
<https://www.freshports.org/graphics/py-pillow/>`_ and packages
are tested by the ports team with all supported FreeBSD versions.

Building From Source
====================
.. _external-libraries:
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 Dockerfiles in our `Docker images repo
<https://github.com/python-pillow/docker-images>`_ to install the
dependencies for some operating systems.
Many of Pillow's features require external libraries:
* **libjpeg** provides JPEG functionality.
* Pillow has been tested with libjpeg versions **6b**, **8**, **9-9d** and
libjpeg-turbo version **8**.
* Starting with Pillow 3.0.0, libjpeg is required by default. It can be
disabled with the ``-C jpeg=disable`` flag.
* **zlib** provides access to compressed PNGs
* Starting with Pillow 3.0.0, zlib is required by default. It can be
disabled with the ``-C zlib=disable`` flag.
* **libtiff** provides compressed TIFF functionality
* Pillow has been tested with libtiff versions **3.x** and **4.0-4.6.0**
* **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 **2.7-2.16**.
* **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.
* **openjpeg** provides JPEG 2000 functionality.
* Pillow has been tested with openjpeg **2.0.0**, **2.1.0**, **2.3.1**,
**2.4.0**, **2.5.0** and **2.5.2**.
* Pillow does **not** support the earlier **1.5** series which ships
with Debian Jessie.
* **libimagequant** provides improved color quantization
* Pillow has been tested with libimagequant **2.6-4.2.2**
* Libimagequant is licensed GPLv3, which is more restrictive than
the Pillow license, therefore we will not be distributing binaries
with libimagequant support enabled.
* **libraqm** provides complex text layout support.
* libraqm provides bidirectional text support (using FriBiDi),
shaping (using HarfBuzz), and proper script itemization. As a
result, Raqm can support most writing systems covered by Unicode.
* libraqm depends on the following libraries: FreeType, HarfBuzz,
FriBiDi, make sure that you install them before installing libraqm
if not available as package in your system.
* Setting text direction or font features is not supported without libraqm.
* Pillow wheels since version 8.2.0 include a modified version of libraqm that
loads libfribidi at runtime if it is installed.
On Windows this requires compiling FriBiDi and installing ``fribidi.dll``
into a directory listed in the `Dynamic-link library search order (Microsoft Learn)
<https://learn.microsoft.com/en-us/windows/win32/dlls/dynamic-link-library-search-order#search-order-for-unpackaged-apps>`_
(``fribidi-0.dll`` or ``libfribidi-0.dll`` are also detected).
See `Build Options`_ to see how to build this version.
* Previous versions of Pillow (5.0.0 to 8.1.2) linked libraqm dynamically at runtime.
* **libxcb** provides X11 screengrab support.
.. tab:: 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 python3-dev python3-setuptools
In Fedora, the command is::
sudo dnf install python3-devel redhat-rpm-config
In Alpine, the command is::
sudo apk add python3-dev py3-setuptools
.. Note:: ``redhat-rpm-config`` is required on Fedora 23, but not earlier versions.
Prerequisites for **Ubuntu 16.04 LTS - 22.04 LTS** are installed with::
sudo apt-get install libtiff5-dev libjpeg8-dev libopenjp2-7-dev zlib1g-dev \
libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python3-tk \
libharfbuzz-dev libfribidi-dev libxcb1-dev
To install libraqm, ``sudo apt-get install meson`` and then see
``depends/install_raqm.sh``.
Prerequisites are installed on recent **Red Hat**, **CentOS** or **Fedora** with::
sudo dnf install libtiff-devel libjpeg-devel openjpeg2-devel zlib-devel \
freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel \
harfbuzz-devel fribidi-devel libraqm-devel libimagequant-devel libxcb-devel
Note that the package manager may be yum or DNF, depending on the
exact distribution.
Prerequisites are installed for **Alpine** with::
sudo apk add tiff-dev jpeg-dev openjpeg-dev zlib-dev freetype-dev lcms2-dev \
libwebp-dev tcl-dev tk-dev harfbuzz-dev fribidi-dev libimagequant-dev \
libxcb-dev libpng-dev
See also the ``Dockerfile``\s in the Test Infrastructure repo
(https://github.com/python-pillow/docker-images) for a known working
install process for other tested distros.
.. tab:: 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
<https://brew.sh/>`_. After you install Homebrew, run::
brew install libjpeg libtiff little-cms2 openjpeg webp
To install libraqm on macOS use Homebrew to install its dependencies::
brew install freetype harfbuzz fribidi
Then see ``depends/install_raqm_cmake.sh`` to install libraqm.
.. tab:: Windows
We recommend you use prebuilt wheels from PyPI.
If you wish to compile Pillow manually, you can use the build scripts
in the ``winbuild`` directory used for CI testing and development.
These scripts require Visual Studio 2017 or newer and NASM.
The scripts also install Pillow from the local copy of the source code, so the
`Installing`_ instructions will not be necessary afterwards.
.. tab:: Windows using MSYS2/MinGW
To build Pillow using MSYS2, make sure you run the **MSYS2 MinGW 32-bit** or
**MSYS2 MinGW 64-bit** console, *not* **MSYS2** directly.
The following instructions target the 64-bit build, for 32-bit
replace all occurrences of ``mingw-w64-x86_64-`` with ``mingw-w64-i686-``.
Make sure you have Python and GCC installed::
pacman -S \
mingw-w64-x86_64-gcc \
mingw-w64-x86_64-python3 \
mingw-w64-x86_64-python3-pip \
mingw-w64-x86_64-python3-setuptools
Prerequisites are installed on **MSYS2 MinGW 64-bit** with::
pacman -S \
mingw-w64-x86_64-libjpeg-turbo \
mingw-w64-x86_64-zlib \
mingw-w64-x86_64-libtiff \
mingw-w64-x86_64-freetype \
mingw-w64-x86_64-lcms2 \
mingw-w64-x86_64-libwebp \
mingw-w64-x86_64-openjpeg2 \
mingw-w64-x86_64-libimagequant \
mingw-w64-x86_64-libraqm
https://www.msys2.org/docs/python/ states that setuptools >= 60 does not work with
MSYS2. To workaround this, before installing Pillow you must run::
export SETUPTOOLS_USE_DISTUTILS=stdlib
.. tab:: FreeBSD
.. Note:: Only FreeBSD 10 and 11 tested
Make sure you have Python's development libraries installed::
sudo pkg install python3
Prerequisites are installed on **FreeBSD 10 or 11** with::
sudo pkg install jpeg-turbo tiff webp lcms2 freetype2 openjpeg harfbuzz fribidi libxcb
Then see ``depends/install_raqm_cmake.sh`` to install libraqm.
.. tab:: Android
Basic Android support has been added for compilation within the Termux
environment. The dependencies can be installed by::
pkg install -y python ndk-sysroot clang make \
libjpeg-turbo
This has been tested within the Termux app on ChromeOS, on x86.
Installing
----------
Once you have installed the prerequisites, to install Pillow from the source
code on PyPI, run::
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow --no-binary :all:
If the prerequisites are installed in the standard library locations
for your machine (e.g. :file:`/usr` or :file:`/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 :file:`setup.py` or
:file:`pyproject.toml`, or by adding environment variables on the command
line::
CFLAGS="-I/usr/pkg/include" python3 -m pip install --upgrade Pillow --no-binary :all:
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.
If you would like to install from a local copy of the source code instead, you
can clone from GitHub with ``git clone https://github.com/python-pillow/Pillow``
or download and extract the `compressed archive from PyPI`_.
After navigating to the Pillow directory, run::
python3 -m pip install --upgrade pip
python3 -m pip install .
.. _compressed archive from PyPI: https://pypi.org/project/pillow/#files
Build Options
^^^^^^^^^^^^^
* Environment variable: ``MAX_CONCURRENCY=n``. Pillow can use
multiprocessing to build the extension. Setting ``MAX_CONCURRENCY``
sets the number of CPUs to use, or can disable parallel building by
using a setting of 1. By default, it uses 4 CPUs, or if 4 are not
available, as many as are present.
* Config settings: ``-C zlib=disable``, ``-C jpeg=disable``,
``-C tiff=disable``, ``-C freetype=disable``, ``-C raqm=disable``,
``-C lcms=disable``, ``-C webp=disable``, ``-C webpmux=disable``,
``-C jpeg2000=disable``, ``-C imagequant=disable``, ``-C xcb=disable``.
Disable building the corresponding feature even if the development
libraries are present on the building machine.

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.
* Config settings: ``-C raqm=vendor``, ``-C fribidi=vendor``.
These flags are used to compile a modified version of libraqm and
a shim that dynamically loads libfribidi at runtime. These are
used to compile the standard Pillow wheels. Compiling libraqm requires
a C99-compliant compiler.
* Build flag: ``-C platform-guessing=disable``. 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: ``-C debug=true``. Adds a debugging flag to the include and
library search process to dump all paths searched for and found to
stdout.
Sample usage::
python3 -m pip install --upgrade Pillow -C [feature]=enable

.. _platform-support:
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.
Continuous Integration Targets
