How to Create PDF Files in Python

Python PDF Library: IronPDF

IronPDF is a powerful Python library specifically designed for creating PDF documents from HTML. Its user-friendly APIs make it easy to generate and customize PDFs with various features, including:

1. Adding text, images, and other types of content
2. Choosing fonts, colors, and controlling document layout and formatting.

IronPDF can be seamlessly integrated into .NET, Java, and Python applications, enabling versatile PDF generation across multiple platforms.

In addition to its powerful PDF generation capabilities, IronPDF offers a wide range of features. These encompass file format conversion, efficient text and data extraction from PDFs, and the ability to secure PDFs through password encryption.

Steps to Create PDF Document in a Python Script

 pip install ironpdf

# Import statement for IronPDF for Python
from ironpdf import *

# Import statement for IronPDF for Python
from ironpdf import *

# Apply your license key
License.LicenseKey = "IRONPDF-MYLICENSE-KEY-1EF01"

# Apply your license key
License.LicenseKey = "IRONPDF-MYLICENSE-KEY-1EF01"

Convert HTML String into PDF Document

Use the RenderHtmlAsPdf method to generate a new PDF document from an HTML string.

Simply provide the HTML markup as the parameter for the RenderHtmlAsPdf method. IronPDF will perform the conversion, resulting in a PdfDocument instance.

# Instantiate Renderer
renderer = ChromePdfRenderer()

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

# Instantiate Renderer
renderer = ChromePdfRenderer()

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

Once the HTML string has been successfully converted to a PDF document, use the SaveAs method to save the PDF to a path on the local system:

# Export to a file or Stream
pdf.SaveAs("htmlstring_to_pdf.pdf")

# Export to a file or Stream
pdf.SaveAs("htmlstring_to_pdf.pdf")

A PDF file named "htmlstring_to_pdf.pdf" will be created, preserving the contents of the original HTML string.

Generate PDF from HTML file in Python

To generate a PDF document from an HTML file stored locally in Python, follow the code provided below:

# Instantiate Renderer
renderer = ChromePdfRenderer()

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

# Export to a file or Stream
pdf.SaveAs("htmlfile_to_pdf.pdf")

# Instantiate Renderer
renderer = ChromePdfRenderer()

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

# Export to a file or Stream
pdf.SaveAs("htmlfile_to_pdf.pdf")

In the code snippet above, the RenderHtmlFileAsPdf method is used to create a PDF document from an HTML file. You need to provide a string or path specifying the location of the HTML file on the filesystem.

IronPDF renders the HTML elements, including any associated CSS and JavaScript, just like a web browser would. This ensures accurate representation of the content in the resulting PDF.

Finally, use the SaveAs method to save the generated PDF to a specific location on your system, similar to the previous example.

Create PDF from URL in Python

To create a PDF document from a web page in Python, utilize the RenderUrlAsPdf method. Simply provide the URL of the desired webpage as an argument to the method, as illustrated in the code snippet below:

# Instantiate Renderer
renderer = ChromePdfRenderer()

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

# Export to a file or Stream
pdf.SaveAs("url.pdf")

# Instantiate Renderer
renderer = ChromePdfRenderer()

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

# Export to a file or Stream
pdf.SaveAs("url.pdf")

More information about converting Web Pages to PDFs is available on the URL to PDF Code Example page.

Exploring PDF Formatting Options

To customize the formatting of your PDF files, you can utilize the RenderingOptions attribute. This class provides various configurable settings to achieve the desired layout and appearance of your PDF documents. Some of the settings you can modify include page orientation, page size, margin size, and more. Set attributes available in RenderingOptions to generate PDF documents with the desired settings. Refer to this Code Example for more information about how to use the RenderingOptions.

Secure PDF Files with Passwords

To add password protection to PDF files, you can utilize the SecuritySettings attribute of the PdfDocument object. Begin by accessing the SecuritySettings attribute and assign a password to the UserPassword attribute, specified as a string.

For instance, let's consider protecting the PDF document created in the "URL to PDF" example:

# Set user password for PDF document security
pdf.SecuritySettings.UserPassword = "sharable"

# Save the password-protected PDF
pdf.SaveAs("protected.pdf")

# Set user password for PDF document security
pdf.SecuritySettings.UserPassword = "sharable"

# Save the password-protected PDF
pdf.SaveAs("protected.pdf")

The PDF file has been successfully password-protected. When attempting to open the file, a password prompt will be displayed. Simply enter the correct password to access the contents of the PDF file.
