Library comparison summary to generate PDF with Python

Purpose of this article

When outputting the quotation in PDF, I tried to identify the merits of the related library. The purpose of this article is to present the implementation method and output in the library so that they can be compared.

This article lists and compares the PDF output libraries of the two methods. The method and various libraries are as follows.

--Export HTML to PDF - django-wkhtmltopdf - django_xhtml2pdf - WeasyPrint --What generates PDF from code - reportlab

We also pay attention to the following points regarding comparison.

--Ease of use of the library -Is it easy to use? -Does the code become complicated? -Is the operation heavy? -Is it necessary to install software separately to make it work?

--Maintainability -Is it easy to maintain? --Library update frequency -Is the quality of the output PDF not a problem? -Is there a lot of information on the net?


I will leave a personal subjective comparison.

HTML to PDF django-wkhtmltopdf

Documentation django-wkhtmltopdf 3.2.0 documentation

This is a library that wraps wkhtmltopdf, which appears at the top of the search when you search with Python PDF by Google search, for django. It supports Django's class-based view and is very easy to deploy. The generated PDF is also output cleanly by default. However, since it is necessary to install software separately, it seems that it will be difficult to install it on App Engine (verification required).

Installation method

$ pipenv install django-wkhtmltopdf

Software installation is required separately from wkhtmltopdf.


from wkhtmltopdf.views import PDFTemplateView

class PdfSampleView(PDFTemplateView):
    filename = 'my_psdf.pdf'    
    template_name = "pdf_sample/sample.html"

Generated PDF


A library that wraps the library django_xhtml2pdf that converts HTML to PDF with Python for Django. A mixin for class-based views is provided and easy to use. In addition, decorators are supported as standard. However, there are few documents and few options. Also, probably because the interpretation of CSS is unique, it is output with a structure different from normal HTML.

xhtml2pdf / django-xhtml2pdf

Installation method

$ pipenv install django_xhtml2pdf


from django_xhtml2pdf.views import PdfMixin

class Xhtml2pdfSampleView_(PdfMixin, TemplateView):
    template_name = "pdf_sample/sample.html"

Generated PDF


PDF generation tools and libraries close to wkhtmltopdf. The documentation is extensive. Although it is not as good as wkhtmltopdf, it outputs a higher quality PDF than xhtml. There is little difference in the output with HTML compared to xhtml. However, looking at the installation documentation, it seems difficult for App Engine because it needs to be installed separately from the package (requires investigation).

WeasyPrint — WeasyPrint 51 documentation


from weasyprint import HTML, CS
from django.http import HttpResponse
from django.template.loader import get_templat

class WeasyPrintView(TemplateView):
    template_name = 'pdf_sample/sample.html'

    def get(self, request, *args, **kwargs):

        html_template = get_template('pdf_sample/sample.html')
        context = super().get_context_data(**kwargs)

        html_str = html_template.render(context)  
        pdf_file = HTML(string=html_str, base_url=request.build_absolute_uri()).write_pdf(

        response = HttpResponse(pdf_file, content_type='application/pdf')
        response['Content-Disposition'] = 'filename="fuga.pdf"'

        return response

Generated PDF



It is a library that is generated by actually specifying the layout on the Python code. It is inevitably long because it happens on the code including the style. PDF generation can be executed without any problem. Also, since all data can be inserted in code, the degree of freedom of implementation is very high. Since there are a lot of options and documents, it is possible to create a set of books.
