Interactive forms in PDFs are valuable tools that allow users to fill in information, complete surveys, or sign documents electronically. However, these forms can also add layers of complexity to a PDF, impacting both file size and the overall user experience. When forms are no longer needed, or when a document needs to be simplified for distribution or archiving, removing these interactive elements can be beneficial. In this article, we will demonstrate how to remove forms from a PDF document in Python using Spire.PDF for Python.

Remove a Specific Form from a PDF Document in Python

Spire.PDF for Python allows you to remove specific form fields from a PDF file by using either the indexes or the names of the form fields. The detailed steps are as follows.

• Create an instance of the PdfDocument class.
• Load a PDF document containing form fields using the PdfDocument.LoadFromFile() method.
• Get the form of the document using the PdfDocument.Form property.
• Get the form field collection using the PdfFormWidget.FieldsWidget property.
• Remove a specific form field by its index using the PdfFormFieldWidgetCollection.RemoveAt(index) method. Or retrieve a form field by its name using the PdfFormFieldWidgetCollection[name] property, and then remove it using the PdfFormFieldWidgetCollection.Remove(field) method.
• Save the resulting document using the PdfDocument.SaveToFile() method.

from spire.pdf.common import *
from spire.pdf import *

# Create an instance of the PdfDocument class
doc = PdfDocument()
# Load a PDF file
doc.LoadFromFile("Forms.pdf")

# Get the form of the document
pdfForm = doc.Form
formWidget = PdfFormWidget(pdfForm)

# Get the form field collection
field_collection = formWidget.FieldsWidget

# Remove a specific form field by its index
field_collection.RemoveAt(0)

# Or remove a specific form field by its name
# text_box = field_collection["Name"]
# field_collection.Remove(text_box)

# Save the resulting document
doc.SaveToFile("remove_specific_form.pdf")
doc.Close()

Remove All Forms from a PDF Document in Python

To remove all form fields from a PDF document, you need to iterate through the form field collection, and then remove each form field from the collection using the PdfFormFieldWidgetCollection.RemoveAt(index) method. The detailed steps are as follows.

• Create an instance of the PdfDocument class.
• Load a PDF document containing form fields using the PdfDocument.LoadFromFile() method.
• Get the form of the document using the PdfDocument.Form property.
• Get the form field collection using the PdfFormWidget.FieldsWidget property.
• Iterate through all form fields in the collection.
• Remove each form field from the collection using the PdfFormFieldWidgetCollection.RemoveAt(index) method.
• Save the resulting document using the PdfDocument.SaveToFile() method.

from spire.pdf.common import *
from spire.pdf import *

# Create an instance of the PdfDocument class
doc = PdfDocument()
# Load a PDF file
doc.LoadFromFile("Forms.pdf")

# Get the form of the document
pdfForm = doc.Form
formWidget = PdfFormWidget(pdfForm)

# Get the form field collection
field_collection = formWidget.FieldsWidget

# Check if there are any form fields in the collection
if field_collection.Count > 0:
    # Iterate through all form fields in the collection
    for i in range(field_collection.Count - 1, -1, -1):
        # Remove the current form field from the collection
        field_collection.RemoveAt(i)

# Save the resulting document
doc.SaveToFile("remove_all_forms.pdf")
doc.Close()
