Use jinja templates to fill and sign pdf forms.

Project description

Use jinja templates to fill and sign PDF forms.

You can use this library to fill out a PDF form using data from an external source such as a database or an excel file. Use a PDF editing software to edit the form and specifiy a jinja template in the tooltip property of the form field.


You’ll need the pdftk library. If you want to paste images, you’ll need whatever dependencies are necessary for Pillow to load your preferred image format. Most of the packages below are taken from the Pillow documentation. You don’t need all of them. In most cases, just pdftk will do.


apt-get install python-dev python-pip libtiff5-dev libjpeg8-dev \
    zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev \
    tk8.6-dev python-tk pdftk libmagickwand-dev

You can install pdfjinja with pip:

$ pip install pdfjinja
$ pdfjinja -h


See examples/sample.pdf for an example of a pdf file with jinja templates. The template strings are placed in the tooltip property for each form field in the pdf.

See examples/output.pdf for the output. The data that the form is filled with comes from examples/sample.json.


$ pdfjinja -j examples/simple.json examples/sample.pdf examples/output.pdf


$ pdfjinja --font examples/open-sans/regular.ttf \
           --json examples/sample.json \
           examples/sample.pdf \


from pdfjinja import PdfJinja

pdfjinja = PdfJinja('form.pdf')
pdfout = pdfjinja(dict(firstName='Faye', lastName='Valentine'))
pdfout.write(open('filled.pdf', 'wb'))

If you are using this with Flask as a webserver:

from flask import current_app
from pdfjinja import PdfJinja
pdf = PdfJinja('form.pdf', current_app.jinja_env)

See examples/ for a more detailed python example. It might also be helpful to example the sample pdf template in examples/sample.pdf.
