How to Fill PDF Form in Python (Tutorial)
Instead of manually filling PDF fields one by one, we will focus on programmatically filling PDFs in this article. This approach becomes useful when an application's user interface enhances the user experience, but the PDF files need to be generated electronically for archiving purposes.
Once all the user input data has been collected, it becomes necessary to programmatically create PDF forms. These filled-out documents can then be saved for future use or modified as needed. There are several Python PDF libraries available for working with PDFs, including PyPDF2, ReportLab, IronPDF, and more. In this article, we will specifically explore how to use IronPDF for filling interactive forms.
How to Fill PDF Form in Python
- Install the Python library required for filling PDF forms
- Load an existing PDF document that contains form fields
- Access the desired form field using the
FindFormFieldmethod of the Form attribute - Populate the form field by assigning a value to the Value attribute
- Export the modified PDF document

Using Python Code to Fill PDF Documents Programmatically
Below is an illustrative code snippet showcasing the utilization of the IronPDF library to create and populate PDF forms using HTML markup. The provided code imports the essential classes from the IronPDF library.
from ironpdf import *
# Define HTML content for a simple form
form_html = """
<html>
<body>
<h2>Editable PDF Form</h2>
<form>
First name: <br> <input type='text' name='firstname' value=''> <br>
Last name: <br> <input type='text' name='lastname' value=''>
</form>
</body>
</html>
"""
# Instantiate a PDF renderer
renderer = ChromePdfRenderer()
# Set the option to create PDF forms from HTML
renderer.RenderingOptions.CreatePdfFormsFromHtml = True
# Render the HTML content as a PDF file and save it
renderer.RenderHtmlAsPdf(form_html).SaveAs("BasicForm.pdf")
# Load the created PDF document
form_document = PdfDocument.FromFile("BasicForm.pdf")
# Access the "firstname" field and set its value
first_name_field = form_document.Form.FindFormField("firstname")
first_name_field.Value = "Minnie"
print("FirstNameField value: {}".format(first_name_field.Value))
# Access the "lastname" field and set its value
last_name_field = form_document.Form.FindFormField("lastname")
last_name_field.Value = "Mouse"
print("LastNameField value: {}".format(last_name_field.Value))
# Save the filled form to a new PDF file
form_document.SaveAs("FilledForm.pdf")from ironpdf import *
# Define HTML content for a simple form
form_html = """
<html>
<body>
<h2>Editable PDF Form</h2>
<form>
First name: <br> <input type='text' name='firstname' value=''> <br>
Last name: <br> <input type='text' name='lastname' value=''>
</form>
</body>
</html>
"""
# Instantiate a PDF renderer
renderer = ChromePdfRenderer()
# Set the option to create PDF forms from HTML
renderer.RenderingOptions.CreatePdfFormsFromHtml = True
# Render the HTML content as a PDF file and save it
renderer.RenderHtmlAsPdf(form_html).SaveAs("BasicForm.pdf")
# Load the created PDF document
form_document = PdfDocument.FromFile("BasicForm.pdf")
# Access the "firstname" field and set its value
first_name_field = form_document.Form.FindFormField("firstname")
first_name_field.Value = "Minnie"
print("FirstNameField value: {}".format(first_name_field.Value))
# Access the "lastname" field and set its value
last_name_field = form_document.Form.FindFormField("lastname")
last_name_field.Value = "Mouse"
print("LastNameField value: {}".format(last_name_field.Value))
# Save the filled form to a new PDF file
form_document.SaveAs("FilledForm.pdf")Firstly, we generate a PDF form by converting an HTML form marked up using the PdfDocument.RenderHtmlAsPdf method. The RenderingOptions attribute is used to set the CreatePdfFormsFromHtml to true, which makes the form within the HTML markup editable. The resulting PDF is then saved to the specified output location using the SaveAs method.
Output
Secondly, we load the created PDF utilizing the PdfDocument.FromFile method. By utilizing the FindFormField method, we access the specified form fields based on their respective names. To populate the firstname and lastname input fields, we assign values to their Value attributes. Finally, the modified PDF is saved to a new file using the SaveAs method.
