Converting HTML to PDF files using Python

by

Yes, you can convert HTML files to PDF using Python. Here is one way to do it using the pdfkit library:

  1. Install the pdfkit library using pip:
pip install pdfkit
  1. Install the wkhtmltopdf library on your system. This library is required by pdfkit to convert HTML to PDF. You can download it from the official website: https://wkhtmltopdf.org/downloads.html
  2. Once you have installed the pdfkit and wkhtmltopdf libraries, you can use the following code to convert an HTML file to PDF:
import pdfkit

# set the path to the input HTML file
input_file = 'input.html'

# set the path to the output PDF file
output_file = 'output.pdf'

# configure the options for pdfkit
options = {
    'page-size': 'Letter',
    'margin-top': '0mm',
    'margin-right': '0mm',
    'margin-bottom': '0mm',
    'margin-left': '0mm'
}

# convert the HTML file to PDF
pdfkit.from_file(input_file, output_file, options=options)

In this code, we first import the pdfkit library. We then set the path to the input HTML file and the path to the output PDF file. We configure some options for pdfkit that control the page size and margins of the PDF file. Finally, we use the from_file() method of pdfkit to convert the HTML file to PDF.

Note that you can also convert HTML strings to PDF using pdfkit by using the from_string() method instead of from_file().

Working with PDFKit in Python:

PDFKit is a Python library that allows you to convert HTML to PDF using various tools and options. Here are some common tasks you can perform using PDFKit:

1. Installing PDFKit

You can install PDFKit using pip, the package manager for Python. Open a command prompt or terminal and type the following command:

pip install pdfkit

2. Converting HTML to PDF

PDFKit provides several methods to convert HTML to PDF. The most common one is from_file(), which takes an input HTML file path and an output PDF file path. Here is an example:

import pdfkit

input_file = 'example.html'
output_file = 'example.pdf'

pdfkit.from_file(input_file, output_file)

You can also convert HTML from a string using from_string(). Here is an example:

import pdfkit

input_html = '<html><body><h1>Hello, World!</h1></body></html>'
output_file = 'example.pdf'

pdfkit.from_string(input_html, output_file)

3. Setting Options

PDFKit provides many options to control the conversion process, such as page size, margins, and orientation. You can set these options using a dictionary and pass it to the conversion method. Here is an example:

import pdfkit

input_file = 'example.html'
output_file = 'example.pdf'

options = {
    'page-size': 'Letter',
    'margin-top': '0mm',
    'margin-right': '0mm',
    'margin-bottom': '0mm',
    'margin-left': '0mm',
}

pdfkit.from_file(input_file, output_file, options=options)

4. Using a Configuration File

You can also use a configuration file to set options for PDFKit. To do this, create a configuration file (e.g., config.yml) with the options you want to set:

# config.yml
page-size: Letter
margin-top: 0mm
margin-right: 0mm
margin-bottom: 0mm
margin-left: 0mm

Then, load the configuration file using the configuration() method:

import pdfkit

input_file = 'example.html'
output_file = 'example.pdf'
config_file = 'config.yml'

pdfkit.configuration(wkhtmltopdf=config_file)

pdfkit.from_file(input_file, output_file)

5. Handling Errors

PDFKit can raise exceptions during the conversion process. You should handle these exceptions in your code to prevent crashes and log errors. Here is an example:

import pdfkit

input_file = 'example.html'
output_file = 'example.pdf'

try:
    pdfkit.from_file(input_file, output_file)
except pdfkit.Error as e:
    print('Conversion failed:', str(e))

This code catches any exception raised by PDFKit and prints an error message to the console.
