PyMuPDF should be installed using pip with:
python -m pip install --upgrade pip python -m pip install --upgrade pymupdf
This will install from a Python wheel if one is available for your platform.
If a suitable Python wheel is not available, pip will automatically build from source using a Python sdist.
This requires C/C++ development tools and SWIG to be installed:
- On Unix-style systems such as Linux, OpenBSD and FreeBSD,
use the system package manager to install SWIG.
- For example on Debian Linux, do:
sudo apt install swig
- For example on Debian Linux, do:
- On Windows:
- Install Visual Studio 2019. If not installed in a standard location, set
environmental variable
PYMUPDF_SETUP_DEVENV
to the location of thedevenv.com
binary. - Install SWIG by following the instructions at: https://swig.org/Doc4.0/Windows.html#Windows_installation
- Install Visual Studio 2019. If not installed in a standard location, set
environmental variable
- On MacOS, install MacPorts using the instructions at:
https://www.macports.org/install.php
- Then install SWIG with:
sudo port install swig
- You may also need:
sudo port install swig-python
- Then install SWIG with:
As of PyMuPDF-1.20.0
, the required MuPDF source code is already in the
sdist and is automatically built into PyMuPDF.
Wheels are available for Windows (32-bit Intel, 64-bit Intel), Linux (64-bit Intel, 64-bit ARM) and Mac OSX (64-bit Intel, 64-bit ARM), Python versions 3.7 and up.
Wheels are not available for Python installed with Chocolatey on Windows. Instead install Python using the Windows installer from the python.org website, see: http://www.python.org/downloads
PyMuPDF does not support Python versions prior to 3.7. Older wheels can be found in this repository and on PyPI. Please note that we generally follow the official Python release schedules. For Python versions dropping out of official support this means, that generation of wheels will also be ceased for them.
There are no mandatory external dependencies. However, some optional feature are available only if additional components are installed:
- Pillow is required for :meth:`Pixmap.pil_save` and :meth:`Pixmap.pil_tobytes`.
- fontTools is required for :meth:`Document.subset_fonts`.
- pymupdf-fonts is a collection of nice fonts to be used for text output methods.
- Tesseract-OCR for optical character recognition in images and document pages. Tesseract is separate software, not a Python package. To enable OCR functions in PyMuPDF, the software must be installed and the system environment variable
"TESSDATA_PREFIX"
must be defined and contain thetessdata
folder name of the Tesseract installation location. See below.
Note
You can install these additional components at any time -- before or after installing PyMuPDF. PyMuPDF will detect their presence during import or when the respective functions are being used.
First get a PyMuPDF source tree:
Clone the git repository at https://github.com/pymupdf/PyMuPDF, for example:
git clone https://github.com/pymupdf/PyMuPDF.git
Or download a
.zip
or.tar.gz
source release from https://github.com/pymupdf/PyMuPDF/releases.
Install SWIG etc as described above, then build PyMuPDF:
cd PyMuPDF && python setup.py install
- This will automatically download a specific hard-coded MuPDF source release, and build it into PyMuPDF.
- One can build with a different MuPDF (for example one installed on the
system, or a local custom build) by setting environmental variables.
- See the documentation at the start of
setup.py
for more information.
- See the documentation at the start of
If you do not intend to use this feature, skip this step. Otherwise, it is required for both installation paths: from wheels and from sources.
PyMuPDF will already contain all the logic to support OCR functions. But it additionally does need Tesseract's language support data, so installation of Tesseract-OCR is still required.
The language support folder location must currently [1] be communicated via storing it in the environment variable "TESSDATA_PREFIX"
.
So for a working OCR functionality, make sure to complete this checklist:
- Install Tesseract.
- Locate Tesseract's language support folder. Typically you will find it here:
- Windows:
C:\Program Files\Tesseract-OCR\tessdata
- Unix systems:
/usr/share/tesseract-ocr/4.00/tessdata
- Windows:
- Set the environment variable
TESSDATA_PREFIX
- Windows:
set TESSDATA_PREFIX=C:\Program Files\Tesseract-OCR\tessdata
- Unix systems:
export TESSDATA_PREFIX=/usr/share/tesseract-ocr/4.00/tessdata
- Windows:
- Set the environment variable
Note
This must happen outside Python -- before starting your script. Just manipulating os.environ
will not work!
