Summary - Converting HTML to PDF using Python is essential for generating reports, invoices, and documentation dynamically. This article explores multiple methods for performing the conversion efficiently and introduces an advanced tool to simplify the process.

PDFs are commonly used to share documents without losing their layout. When dealing with web applications, it is possible that HTML content needs to be converted into a PDF format for reports, receipts, or other formal documents. Python has a number of libraries that can easily and efficiently do this.

As HTML is mainly dedicated to web content, its conversion to a standardized and portable format such as PDF guarantees data consistency across platforms. Whether it's invoices, web articles, or automated reports, HTML-to-PDF conversion is important in managing documents.

In this tutorial, we will discuss various ways to convert HTML to PDF in Python and also present a Document Converter, a clever tool for effortless document conversion.

Why Convert HTML to PDF?

There are a number of reasons why HTML to PDF conversion is useful:

1. Maintains Layout: HTML content is displayed differently based on browsers, screen resolutions, and sizes. Converting it to PDF maintains the layout, fonts, and styles irrespective of the device or application used to view it.
2. Simple Printing & Sharing: PDFs are rendered everywhere, and they do not change their appearance when printed out, unlike HTML, which will vary depending on the browser setting.
3. Security & Compliance: PDFs can be encrypted, password-protected, and digitally signed, making them ideal for legal documents and confidential information exchange.
4. Archiving & Storage: A PDF is not like an HTML file that relies on JavaScript and CSS and must be stored in the long term with fear of broken links or lost stylesheets.

How to Convert HTML to PDF Using Python

Python provides several libraries to achieve HTML to PDF conversion. Below are three popular methods, each with its advantages.

Method 1: Using pdfkit and wkhtmltopdf

An easy and powerful solution to generate HTML to PDF in Python is with the use of the pdfkit library as a wrapper around wkhtmltopdf. The most frequent purpose to use it is to copy the entire page from the web with its default styling.

Step 1: Install the required libraries:

pip install pdfkit
sudo apt install wkhtmltopdf # For Linux users

(On Windows, download and install wkhtmltopdf and put it on the system path.)

Step 2: Use the following Python code to convert an HTML file to PDF:

import pdfkit
pdfkit.from_file('sample.html', 'output.pdf')

Alternatively, to convert an HTML string:

html_content = '

Hello, PDF!

'
pdfkit.from_string(html_content, 'output.pdf')

Step 3: If you want to convert a webpage directly from a URL:

pdfkit.from_url('https://example.com', 'output.pdf')

Pros:

• Preserves web page layout accurately.
• Supports CSS and inline styles.
• Can convert live web pages directly.

Cons:

• Requires external wkhtmltopdf installation.
• May not handle JavaScript-heavy pages well.

Method 2: Using reportlab

The reportlab library enables programmatic PDF generation but does not render full HTML/CSS. It is best suited for creating PDFs from scratch rather than converting existing web pages.

Step 1: Install the library:

pip install reportlab

Step 2: Generate a PDF from basic text content:

from reportlab.pdfgen import canvas
c = canvas.Canvas("output.pdf")
c.drawString(100, 750, "Hello, PDF!")
c.save()

Pros:

• Lightweight and easy to use.
• Good for generating structured reports with dynamic data.

Cons:

• Does not support HTML or CSS rendering.
• Requires manual positioning of text and images.

Method 3: Using weasyprint

weasyprint is another library that converts HTML and CSS into PDFs with high accuracy. It supports complex layouts and styles better than pdfkit.

Step 1: Install weasyprint:

pip install weasyprint

Step 2: Convert an HTML file to PDF:

from weasyprint import HTML
HTML(filename='sample.html').write_pdf('output.pdf')

Step 3: Convert an HTML string to PDF:

html_content = "

Styled PDF Example

This is a test document.

"
HTML(string=html_content).write_pdf('output.pdf')

Limitations of the Manual Method

While these Python libraries provide effective solutions, they come with some limitations:

• Dependency Installation: Many of these solutions require external tools like wkhtmltopdf, which must be installed separately.
• Limited JavaScript Support: Most libraries do not execute JavaScript content, meaning dynamic web elements might not be properly rendered.
• Formatting Issues: Some libraries struggle with complex layouts, advanced CSS styles, or specific fonts, leading to inconsistencies in the converted PDF.
• Technical Expertise Required: Users need to understand Python scripting and HTML structure to configure the conversion properly.
