Convert HTML to an image in Python

Question

I want to convert following HTML to PNG image in Python. For example:

<html>
<b>Bold text</b>
</html>

I have tried 'pisa' but it converts html to PDF, not to image. I can convert HTML to PDF and then convert PDF to PNG, but I was wondering if there is any direct solution.

can you help me in converting html source code generated from selenium to PDF? — May 15, 2019
Hey @SAK!

You can use the pdfkit library to convert the html code to PDF.

Firsty, you'll have to install wkhtmltopdf and pdfkit for this:

$ sudo apt-get install wkhtmltopdf $ pip install pdfkit

Next, to convert the code to PDF, refer to the following Python script:

import pdfkit #If the source code is a string, then use this; pdfkit.from_string('<string>', '<Output filename with .pdf as extension>') #If the source code is a html file, then use this: pdfkit.from_file('<html filename>','<Output filename with .pdf as extension>') — Omkar, May 15, 2019
Hi Omkar,

The problem here is I'm doing this work Online where i just have option to use Python package... i cant use wkhtmltopdf there... is there any other way? — May 15, 2019
Can you try using the script without installing wkhtmltopdf? Check if it works, or post the error that you get. — Omkar, May 15, 2019
"OSError: No wkhtmltopdf executable found: "b''" If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf"

This is the error i get if i just use pdfkit without wkhtmltopdf — May 15, 2019
Okay, That approach won't work. You said you are working online, can you mention what framework or tool you are using? Maybe can find an API for your requirement. — Omkar, May 15, 2019
Im working on client's environment, where i have access to using Python alone and actual problem is to webscrape content directly to PDF using selenium (or any other option if available) — May 15, 2019
I don't see a way to do this without using external libraries. @SAK

Directly creating a file and writing in it using open method also won't work. You have to at least run a pip install command. — Omkar, May 15, 2019
K sure. Whats the way to make it run using any package installed via pip??? — May 15, 2019
Ok so first install the pyfpdf library:

$ pip install pyfpdf

Then in your python script, store the html source code in a variable:

html_source= # html source code.

Import pyfpdf, add the below line at the beginning of your script:

import pyfpdf

Write the text to pdf:

pdf = pyfpdf.FPDF(format='letter') pdf.add_page() pdf.set_font("Arial", size=12) pdf.cell(200, 10, txt=html_source align="C") pdf.output("htmlsource.pdf") — Omkar, May 15, 2019
