from fpdf import FPDF, HTMLMixin
# creating a class inherited from both FPDF and HTMLMixin
class MyFPDF(FPDF, HTMLMixin):
# instantiating the class
pdf = MyFPDF()
# adding a page
pdf.add_page()
# opening html file 
file = open("file.html", "r")
# extracting the data from hte file as a string
Data = file.read()
# HTMLMixin write_html method
pdf.write_html(data)
#saving the file as a pdf
pdf.output('Python_fpdf.pdf', 'F')

So we have a lot of options to choose from. The only question remains which one is more suitable for me. I would say it depends on your application and what you actually need to do. For example, if you want to build a PDF from scratch, or you just want to convert HTML into a PDF, or you want to fill a particular template and convert it into a specific format.

So if you want to convert HTML into PDF, I believe PDFKit , FPDF , and Wkhtmltopdf are the best options you have. But PDFkit is the more popular one of them. On the other hand, if you want to render PDFs, your options are Pyppeteer and Reportlab.

Reportlab advantage is that it supports a wide variety of graphs like line plots and bar charts and can embed images. On the other hand, it doesn’t provide a method for creating a footer and footnotes and can embed only JPEG images, but with the right python extension, you can extend this to 30 more formats. Reportlab is also more difficult for beginner users and more comprehensive.

On the other hand, Pyppeteer provides better rendering and is easier if you are familiar with its javascript version but only supports specific browsers like chrome and chromium that must be available on your machine to work with this tool.

We had a brief introduction to some of the tools/ libraries like FPDF , wkHTMLToPdf , Pyppeteer , ReportLab, and PDFKit . We also compared them in different properties like complexity, size of generated files, resolution, and Features.
Finally, if you want to have a tool with all the features of these libraries and more, in that case, I recommend that you check out APITemplate.io , which is a tool that can help you generate PDF quickly with PDF generating API over the cloud and totally compatible with CSS, JavaScript, and Python. It also comes with predefined templates which you can reuse and edit.
