How to Write a PDF File in Python

This post will focus on IronPDF as it is a powerful tool for editing and creating PDF files.

IronPDF for Python

Python offers programmers greater dynamism compared to other languages, enabling them to create graphical user interfaces quickly and easily. As a result, integrating the IronPDF library into Python is a straightforward process. Numerous pre-installed tools, such as PyQt, wxWidgets, Kivy, and various packages and libraries, facilitate the rapid and secure development of comprehensive GUIs.

IronPDF greatly simplifies Python web design and development. This is primarily due to the abundance of Python web development paradigms, including Django, Flask, and Pyramid. Prominent websites and online services like Reddit, Mozilla, and Spotify have successfully utilized these frameworks.

Features of IronPDF

Some key characteristics of the IronPDF are listed below.

• PDF files can be created from a variety of sources such as HTML, HTML5, ASP, PHP, and more. Additionally, image files can be converted to PDF along with HTML files.
• IronPDF has the capability to open encrypted PDF files and modify existing ones.
• Interactive PDF documents can be produced with IronPDF, allowing for actions such as splitting and merging, extracting text and images, rasterizing into images, converting to HTML, printing, filling out interactive forms, and submitting them.
• IronPDF enables the creation of documents from a URL and supports user agents, proxies, cookies, HTTP headers, unique network login credentials, form variables, and user agents that log in using HTML login forms.
• The IronPDF program allows for the inspection and annotation of PDF files.
• Images can be extracted from documents using IronPDF.
• IronPDF enables the addition of headers, footers, text, images, bookmarks, watermarks, and more to documents.
• IronPDF allows for the separation and combination of pages within new or existing documents.
• PDF objects can be created from documents without the need for an Acrobat viewer.
• IronPDF can convert a CSS file into a PDF document.
• Media-type declarations included in CSS files can be utilized to generate documents.

Configure Python Environment

Setup Python

To get started, make sure that Python is properly set up on your computer. Visit the official Python website and download the latest version of Python that corresponds to your operating system. Follow the installation instructions provided to complete the setup.

Once Python is installed, it's recommended to create a virtual environment to keep your project requirements separate. This helps maintain a clean and organized workspace for your conversion process. You can use the venv module to easily create and manage virtual environments.

New Project in PyCharm

For this tutorial, PyCharm, an IDE designed for Python development, is recommended.

Select "New Project" from the menu when PyCharm begins, as illustrated in the figure below.

IronPDF Library Requirement

IronPDF for Python utilizes .NET 6.0 as its primary technology. Therefore, it is essential to have the .NET 6.0 runtime installed on your computer to use IronPDF for Python. Linux and Mac users may need to install .NET before using this Python module. You can obtain the required runtime environment by visiting the following page.

IronPDF Library Setup

To generate, modify, and open files with the ".pdf" extension, the ironpdf package must be installed. Open a terminal window and enter the following command to install the package in PyCharm:

 pip install ironpdf

The installation process of the ironpdf package is shown in the screenshot below.

Create PDF Using IronPDF

Writing PDF files can be achieved in one of three ways:

1. Writing a PDF from a URL.
2. Writing a PDF from a string of HTML.
3. Writing a PDF using an HTML file.

In all three methods, the import statement for ironpdf is common. This import allows you to access the IronPDF library and utilize its features within your code.

from ironpdf import *

from ironpdf import *

Write a PDF from a URL

With IronPDF, creating a PDF document becomes straightforward by generating an HTML file from a URL and converting it to PDF. IronPDF includes a built-in Chrome browser, which functions as a file object to retrieve and download the HTML content. You can use the following code to automatically generate PDF files:

renderer = ChromePdfRenderer()
renderer.RenderUrlAsPdf("https://www.google.co.in/").SaveAs("sample.pdf")

renderer = ChromePdfRenderer()
renderer.RenderUrlAsPdf("https://www.google.co.in/").SaveAs("sample.pdf")

The URL can be converted into a document, resulting in the creation of a PDF file. The output PDF file can then be saved to a specified location. The output of the above code is shown below.

Write a PDF from a string of HTML

IronPDF can indeed be utilized to convert HTML strings into PDF documents. The code provided below demonstrates an example of HTML string to document conversion. It showcases the ability to create PDF files from any HTML element.

from ironpdf import *
renderer = ChromePdfRenderer()
renderer.RenderHtmlAsPdf("<h1>Hello world!!</h1>").SaveAs("sample.pdf")

from ironpdf import *
renderer = ChromePdfRenderer()
renderer.RenderHtmlAsPdf("<h1>Hello world!!</h1>").SaveAs("sample.pdf")

The provided sample code demonstrates how to convert HTML using the RenderHtmlAsPdf method. It allows for the conversion of any number of HTML pages into PDF strings. If desired, the resulting PDF files can be saved to a specified location using the SaveAs function.

Creating a PDF from an HTML File

IronPDF can be used to convert HTML files into PDF files. The following sample HTML code demonstrates how to create documents using IronPDF. Additionally, IronPDF allows you to generate PDF files from any HTML element. You can also utilize an HTML string to generate PDF files.

renderer.RenderHtmlFileAsPdf("demo.html").SaveAs("sample.pdf")

renderer.RenderHtmlFileAsPdf("demo.html").SaveAs("sample.pdf")

The provided sample demonstrates how to convert an HTML file using the RenderHtmlFileAsPdf method. It allows for the conversion of multiple HTML pages from the file into a string representation. By utilizing the code mentioned above, you can easily create a PDF file and save it in the desired location.
