By the end of this article, I am confident that you will possess the necessary knowledge and tools to convert HTML to PDF effortlessly using Python.
This newfound capability will empower you to automate document generation, enhance your applications, and unleash your creativity in producing visually appealing and professional PDF documents.
So, let's embark on this journey together and unlock the potential of HTML to PDF conversion in Python.
To install pdfkit and add it to your Python environment, you can use the following code snippet:
pip install pdfkit
By executing this command in your command-line interface or terminal, you will initiate the installation process for the pdfkit library. pip is the package manager for Python, and it will automatically download and install pdfkit from the Python Package Index (PyPI).
Once the installation is complete, you will have pdfkit it available for use in your Python projects. This library acts as a convenient wrapper around the command-line tool wkhtmltopdf, allowing you to easily convert HTML to PDF using Python code.
With pdfkit successfully installed, we can proceed to the next steps in our HTML to PDF conversion process.
See the below screenshot.
To install wkhtmltopdf, follow the instructions based on your operating system.
Ubuntu:
Open your terminal and run the following command.
sudo apt-get install wkhtmltopdf
Provide your system password when prompted, and the installation will proceed.
macOS:
If you have Homebrew installed, open your terminal and run the following command.
brew install homebrew/cask/wkhtmltopdf
The installation will begin, and Homebrew will take care of the process for you.
Windows:
- Visit the official wkhtmltopdf download page at https://wkhtmltopdf.org/downloads.html.
- Choose the appropriate version of wkhtmltopdf for your Windows version (32-bit or 64-bit).
- Once the download is complete, locate the downloaded file and double-click on it to initiate the installation process.
- Follow the on-screen instructions to complete the installation, selecting the desired options as needed.
- By default, wkhtmltopdf is installed in the path
C:\Program Files\wkhtmltopdf. - To ensure the command is accessible from any location in the command prompt, we need to add the
binfolder to the system's PATH variable in the Environment Variables settings. - For example, add
C:\Program Files\wkhtmltopdf\binto the PATH variable.
Once the installation is complete and the necessary configurations are in place, you'll be ready to utilize wkhtmltopdf for converting HTML to PDF within your Python projects.
Here's an example that demonstrates how to use pdfkit to generate a PDF file from a URL.
import pdfkit
pdfkit.from_url('https://www.google.com/','test.pdf')
In this example, we import the pdfkit module and use the from_url() function to convert the webpage at the specified URL (https://www.google.com/) into a PDF file.
The resulting PDF file is saved with the filename 'test.pdf'.
You can customize the URL and the output filename according to your requirements. Running this code will initiate the conversion process and generate the PDF file from the provided URL.
In this example, we import the pdfkit module and use the from_file() function to convert the HTML file named 'test.html' into a PDF file.
The resulting PDF file is saved with the filename 'example.pdf'.
import pdfkit
pdfkit.from_file('test.html', 'example.pdf')
Make sure to replace 'test.html' with the actual path or filename of your HTML file that you want to convert.
Similarly, you can customize the output filename according to your preference. Running this code will initiate the conversion process and generate the PDF file from the HTML content.
In this example, we define an HTML string html_str that contains a heading and a paragraph. Using from_string(), we convert this HTML string into a PDF file named 'test.pdf'.
import pdfkit
pdfkit.from_string('Hello!', 'test.pdf')
OR
var htmlstr = '<h2>Generate PDF File</h2><p>create PDF file</p>'
pdfkit.from_string(htmlstr, 'test.pdf')
Here's an example that demonstrates how to use pdfkit to convert multiple URLs or files into a single PDF:
Example 1: Converting multiple URLs to PDF:
import pdfkit
pdfkit.from_url(['google.com', 'yandex.ru', 'engadget.com'], 'test.pdf')
In this example, we use the from_url() function and pass a list of URLs (['google.com', 'yandex.ru', 'engadget.com']) to convert multiple webpages into a single PDF file named 'test.pdf'.
Each URL will be converted into a separate page within the generated PDF.
Example 2: Converting multiple HTML files to PDF:
import pdfkit
pdfkit.from_file(['file1.html', 'file2.html'], 'test.pdf')
In this example, we use the from_file() function and provide a list of HTML files (['file1.html', 'file2.html']) to convert multiple HTML files into a single PDF file named 'test.pdf'.
Each HTML file will be converted into a separate page within the generated PDF.
