Documentation – Managing Form Fields

Python-Net: Flatten All Fields

Thu, 19 Feb 2026 00:00:00 +0000

Flattening removes interactivity from PDF forms by merging field values directly into the document layout. In this example, the Form facade from aspose.pdf.facades is used to bind the source PDF and apply the flatten_all_fields() method, which converts all fields into non-editable content.

Initialize pdf_facades.Form() to interact with PDF form fields.
Call ‘bind_pdf()’ to attach the source document.
Call ‘flatten_all_fields()’ to convert all interactive fields into static content.
Save the updated Document.

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Flatten all fields
def flatten_all_fields(infile, outfile):
    """Flatten all fields in a PDF document."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Flatten all fields in the PDF document
    pdf_form.flatten_all_fields()

    # Save updated PDF
    pdf_form.save(outfile)

Python-Net: Flatten Specific Fields

Thu, 19 Feb 2026 00:00:00 +0000

Managing form fields is an important part of PDF processing workflows. Flattening fields removes interactivity by converting form elements into regular page content, while renaming fields helps standardize naming conventions for easier data handling.

Initialize pdf_facades.Form() to access and manage PDF form fields.
Use ‘bind_pdf()’ to attach the input document.
Provide field names and call ‘flatten_field()’ to convert selected fields into static content.
Call ‘flatten_all_fields()’ to remove interactivity from every form field.
Define old and new field names and apply ‘rename_field()’.
Save the updated PDF.

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Flatten specific fields
def flatten_specific_fields(infile, outfile):
    """Flatten specific fields in a PDF document."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Flatten specific fields by their names
    fields_to_flatten = ["First Name", "Last Name"]
    for field_name in fields_to_flatten:
        pdf_form.flatten_field(field_name)

    # Save updated PDF
    pdf_form.save(outfile)

Python-Net: Rename Form Fields

Thu, 19 Feb 2026 00:00:00 +0000

Renaming form fields is useful when aligning PDF forms with internal naming conventions or preparing documents for structured data processing. In this example, the Form facade from the aspose.pdf.facades module is used to bind the source PDF and apply a mapping that replaces old field names with new ones. After updating the field identifiers, the document is saved with the changes applied.

Initialize pdf_facades.Form() to interact with PDF form fields.
Call ‘bind_pdf()’ to attach the PDF document.
Create a list of tuples containing old field names and their corresponding new names.
Iterate through the mapping and call ‘rename_field()’ for each entry.
Save the updated Document.

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Rename form fields
def rename_form_fields(infile, outfile):
    """Rename form fields in a PDF document."""
    # Create Form object
    pdf_form = pdf_facades.Form()

    # Bind PDF document
    pdf_form.bind_pdf(infile)

    # Rename form fields by providing a mapping of old names to new names
    field_renaming_map = [("First Name", "NewFirstName"), ("Last Name", "NewLastName")]
    for old_name, new_name in field_renaming_map:
        pdf_form.rename_field(old_name, new_name)

    # Save updated PDF
    pdf_form.save(outfile)
