Since they maintain formatting across various platforms and devices, PDFs are one of the most popular and adaptable formats for digital documents. Even so, there are situations where more customization or annotation is required, even though PDFs are great at preserving document integrity. This is where IronPDF for Python comes into play, providing strong tools to add text, annotations, and other components to PDF documents dynamically using programming. In this article, we are using IronPDF for Python to add text to the PDF file.

How to Use Python to Add Text to a PDF File

  1. Install the IronPDF library to create and edit PDFs using Python.
  2. Verify that IronPDF is set up in the Python environment.
  3. Add the IronPDF classes that your Python script needs.
  4. Open the PDF file using IronPDF.
  5. Add the text into the PDF file.
  6. Save the new PDF file to a path.

Setup Environment

Prerequisites

Before beginning the guide, ensure the subsequent are set up for your computer:

  • Because IronPDF was developed with the .NET 6.0 SDK, ensure that the .NET 6.0 runtime is installed on your machine.
  • Python 3.0+: You need to have Python 3.0 or a later version installed in order to follow the examples in this lesson.
  • pip: Since IronPDF depends on the Python package installer pip, install it first.

New Project in PyCharm

In this article, PyCharm, an IDE for Python programming, will be utilized.

Choose "New Project" when the PyCharm IDE has launched.

IronPDF Library Requirement

IronPDF is essentially a Python library with support for .NET 6.0. This means that you need to install the .NET 6.0 runtime on your machine in order to use IronPDF in Python projects. Users of Linux and macOS X might need to manually install the .NET runtime before using this Python module. Make sure you have the necessary runtime environment configured by following the .NET website's installation instructions before integrating IronPDF into your development process.

IronPDF Library Setup

Creating, editing, and opening files with the '.pdf' extension requires the installation of the 'IronPDF' package. Open the PyCharm terminal window and type the following command to install this package:

pip install ironpdf

The screenshot below shows the setup for the 'IronPDF' package.

Add Text to PDF using IronPDF

The Python code snippet that is supplied demonstrates how to use IronPDF to efficiently add formatted text to an already-existing PDF document.

# Import IronPDF library
from ironpdf import *     

# Set your license key for IronPDF
License.LicenseKey = "YOUR KEY HERE"

# Text you want to add to the PDF
text_to_add = "This is the text I'm adding to the PDF."

# Optional: Set text formatting using HTML tags (e.g., <b>bold</b> or <i>italic</i>)
formatted_text = f"<b>{text_to_add}</b>"

# Initialize the renderer to convert HTML to PDF
renderer = ChromePdfRenderer()

# Load the existing PDF file
pdf_document = PdfDocument.FromFile("Example.pdf")

# Create a new PDF with the added text using HTML
new_pdf = renderer.RenderHtmlAsPdf(f"<p>{formatted_text}</p>")

# Append the newly created PDF with text to the existing PDF
pdf_document.AppendPdf(new_pdf)

# Save the modified PDF with a new name (optional)
# Replace 'outpdf.pdf' with your desired output path
pdf_document.SaveAs('outpdf.pdf')
# Import IronPDF library
from ironpdf import *     

# Set your license key for IronPDF
License.LicenseKey = "YOUR KEY HERE"

# Text you want to add to the PDF
text_to_add = "This is the text I'm adding to the PDF."

# Optional: Set text formatting using HTML tags (e.g., <b>bold</b> or <i>italic</i>)
formatted_text = f"<b>{text_to_add}</b>"

# Initialize the renderer to convert HTML to PDF
renderer = ChromePdfRenderer()

# Load the existing PDF file
pdf_document = PdfDocument.FromFile("Example.pdf")

# Create a new PDF with the added text using HTML
new_pdf = renderer.RenderHtmlAsPdf(f"<p>{formatted_text}</p>")

# Append the newly created PDF with text to the existing PDF
pdf_document.AppendPdf(new_pdf)

# Save the modified PDF with a new name (optional)
# Replace 'outpdf.pdf' with your desired output path
pdf_document.SaveAs('outpdf.pdf')
PYTHON

In the above program, the license key required for IronPDF operation is set up initially. The text_to_add variable defines the content to be inserted into the PDF in this code example. The formatted_text variable allows for the optional formatting of the text using HTML tags, showcasing the versatility of applying styles like bold.

To start a renderer and enable the script to convert HTML material into a PDF document, it makes use of ChromePdfRenderer. Then, PdfDocument.FromFile() loads the input PDF file, "Example.pdf," readying it for editing. After formatting, the text (contained in HTML tags to preserve order) is converted to a new PdfDocument object (new_pdf) using the RenderHtmlAsPdf method. The newly created PdfDocument (new_pdf) is then appended to the original PdfDocument (pdf_document) using the pdf_document.AppendPdf(new_pdf) method, therefore incorporating the new material seamlessly.

Lastly, using the SaveAs method, the output PDF file is saved as "outpdf.pdf" with the newly added formatted text included in a new PDF page. This method demonstrates how IronPDF may be used to programmatically improve PDF documents. It gives developers the ability to dynamically add formatted text and smoothly incorporate it into pre-existing PDF files, making it appropriate for a variety of applications, from report creation to document customization.

Existing PDF file

The sample PDF that we use is shown below.

OUTPUT PDF

The result of adding text to the new page is seen below.

Conclusion

Finally, IronPDF for Python shows itself to be an effective tool for adding text dynamically to PDF documents. With the use of well-known HTML tags, developers may use this feature to dynamically insert and format text within pre-existing PDF files, giving them a variety of versatile stylistic options like bold and italics. With IronPDF's ChromePdfRenderer, developers can easily add dynamic text elements to documents, making them more useful for a variety of applications. This may be achieved by converting HTML-formatted text into PDF material.

All things considered, IronPDF makes it easier to handle and customize documents in Python programs, enabling developers to precisely and easily meet a wide range of PDF manipulation requirements. IronPDF offers the capabilities required to accomplish complex document customization while preserving the integrity and portability of PDF files, whether the goal is to improve instructional materials, automate the creation of documents, or incorporate branded content into reports.
