• Document Settings: IronPDF offers robust document settings, empowering users to control PDF metadata, set permissions and passwords for enhanced security to generate encrypted PDF files, and seamlessly integrate digital signatures for document authenticity and integrity.

Prerequisites

Before diving into the PDF generation process using IronPDF, ensure that you have the following prerequisites in place:

1. Python Installed: Python programming language needs to be installed on your system. You can download and install the latest version from the official Python website (https://www.python.org/).
2. PyCharm IDE: Use PyCharm or any other Python IDE of your choice. PyCharm is a popular integrated development environment that provides a comfortable workspace for Python development.
3. IronPDF: IronPDF library downloaded from here or installed using PIP (Python Package Manager). .NET runtime is also required to successfully use IronPDF functionality. Linux, Mac, and Windows users can download the .NET 6.0 version from here.

Create a Python Project in PyCharm

Once the prerequisites are met, open PyCharm and create a new Python project. Set up a virtual environment for your project to manage dependencies effectively.

1. Click on File > New Project.
2. In the "New Project" window:
   • Enter a name for your project in the "Location" field.
   • Choose the location where you want to save your project files.
3. Under "Project Interpreter," select the Python interpreter you configured in Step 3.

4. Choose the project type. For a simple Python project, you can stick with the default settings.

   

5. Click Create to create the project.

Install IronPDF for Python Using PIP

To install IronPDF, use the following PIP command in your project's terminal or command prompt:

 pip install ironpdf

This command will automatically download and install the IronPDF library along with its dependencies.

Steps to Generate PDF in Python

Now that IronPDF is installed, we'll explore three common scenarios for PDF generation using IronPDF: from an HTML string, an HTML file, and a URL.

1. Generate PDF using an HTML String

IronPDF allows you to generate PDFs from HTML. For creating PDF files from an HTML string, you can follow these simple steps:

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

# Create a PDF from an HTML string using Python
pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")

# Export the PDF to a file
pdf.SaveAs("output_htmlstring.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

# Create a PDF from an HTML string using Python
pdf = renderer.RenderHtmlAsPdf("<h1>Hello World</h1>")

# Export the PDF to a file
pdf.SaveAs("output_htmlstring.pdf")

This code initializes the ChromePdfRenderer, renders an HTML string as a PDF, and saves the PDF document to a file named "output_htmlstring.pdf".

You can also handle more complex scenarios by including external HTML assets such as images, CSS, and JavaScript:

# Advanced Example with HTML Assets
# Load external HTML assets: Images, CSS, and JavaScript.
# An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", r"C:\site\assets")
myAdvancedPdf.SaveAs("html-with-assets.pdf")

# Advanced Example with HTML Assets
# Load external HTML assets: Images, CSS, and JavaScript.
# An optional BasePath 'C:\\site\\assets\\' is set as the file location to load assets from
myAdvancedPdf = renderer.RenderHtmlAsPdf("<img src='icons/iron.png'>", r"C:\site\assets")
myAdvancedPdf.SaveAs("html-with-assets.pdf")

Output PDF File

After executing the HTML String to PDF code, you will find a file named output_htmlstring.pdf in your project directory, containing the generated PDF document.

2. Generate PDF using an HTML File

Creating a PDF from an existing HTML file is straightforward. Here's an example:

from ironpdf import ChromePdfRenderer      

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

# Create a PDF from an existing HTML file using Python
pdf = renderer.RenderHtmlFileAsPdf("example.html")

# Export the PDF to a file
pdf.SaveAs("output_htmlfile.pdf")

from ironpdf import ChromePdfRenderer      

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

# Create a PDF from an existing HTML file using Python
pdf = renderer.RenderHtmlFileAsPdf("example.html")

# Export the PDF to a file
pdf.SaveAs("output_htmlfile.pdf")

This snippet uses the ChromePdfRenderer to render an HTML file ("example.html") into a PDF using the RenderHtmlFileAsPdf method, and saves it as "output_htmlfile.pdf".

Output PDF File

After executing the above code, you will find a file named output_htmlfile.pdf in your project directory, containing the generated PDF document.

3. Generate PDF using a URL

Generating a PDF from a URL or a local file path is also possible with IronPDF:

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

# Create a PDF from a URL or local file path
pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/python/")

# Export the PDF to a file
pdf.SaveAs("output_url.pdf")

from ironpdf import ChromePdfRenderer

# Instantiate ChromePdfRenderer
renderer = ChromePdfRenderer()

# Create a PDF from a URL or local file path
pdf = renderer.RenderUrlAsPdf("https://ironpdf.com/python/")

# Export the PDF to a file
pdf.SaveAs("output_url.pdf")

In this case, the code renders the content of the specified URL ("https://ironpdf.com/python/") into a PDF and saves the output file as "output_url.pdf".

Output PDF File

After executing the Python program, you will find a file named output_url.pdf in your project directory, containing the generated PDF document.

With these examples, you can leverage IronPDF to cover a range of scenarios for PDF generation in your Python projects. Whether it's simple HTML strings, existing HTML files, or content from URLs, IronPDF provides a seamless and efficient solution for your PDF generation needs.
