eSign Document with Multiple Signatures Leave feedback
On this page
GroupDocs.Signature for Python via .NET allows signing a document with several signatures simultaneously and even apply signatures of different types to the same document.
Doing this is as simple as:
- Create a new instance of the Signature class and pass the source document path or stream as a constructor parameter.
- Instantiate all required sign options objects depending on signature type:
- BarcodeSignOptions - for Barcode signatures;
- DigitalSignOptions - for Digital signatures;
- FormFieldSignOptions - for Form-field signatures;
- ImageSignOptions - for Image signatures;
- MetadataSignOptions - for Metadata signatures;
- QrCodeSignOptions - for QR-code signatures
- StampSignOptions - for Stamp signatures;
- TextSignOptions - for Text signatures.
- Fill the collection with sign options from the previous step.
- Call the Sign method of the Signature class instance and pass the collection of sign options to it.
This code snippet below demonstrates how to eSign a PDF document with multiple signatures at the same time using Python:
from groupdocs.signature import Signature
from groupdocs.signature.options import (
BarcodeSignOptions, DigitalSignOptions, QrCodeSignOptions, TextSignOptions)
from groupdocs.signature.domain import BarcodeTypes, QrCodeTypes
def sign_with_multiple_signatures():
with Signature("sample.pdf") as signature:
# Define text signature options
text_options = TextSignOptions("This is test message")
text_options.left = 100
text_options.top = 360
text_options.width = 200
text_options.height = 30
# Define barcode signature options
barcode_options = BarcodeSignOptions("123456")
barcode_options.encode_type = BarcodeTypes.CODE128
barcode_options.left = 100
barcode_options.top = 420
barcode_options.width = 200
barcode_options.height = 60
# Define QR code signature options
qrcode_options = QrCodeSignOptions("JohnSmith")
qrcode_options.encode_type = QrCodeTypes.QR
qrcode_options.left = 100
qrcode_options.top = 520
qrcode_options.width = 100
qrcode_options.height = 100
# Define digital signature options with a certificate and an appearance image
digital_options = DigitalSignOptions("certificate.pfx")
digital_options.password = "1234567890"
digital_options.image_file_path = "signature.jpg"
digital_options.left = 350
digital_options.top = 520
digital_options.width = 160
digital_options.height = 100
# Sign the document with the list of signature options
list_options = [text_options, barcode_options, qrcode_options, digital_options]
result = signature.sign("signed_multiple.pdf", list_options)
print(f"Signed with {len(result.succeeded)} signatures:")
for item in result.succeeded:
print(f" {item.signature_type.name}")
if __name__ == "__main__":

Here’s a more advanced example showing how to add multiple signatures with different styles and positions. Each signature is placed with an alignment and a margin from the page edges:
from groupdocs.signature import Signature
from groupdocs.signature.options import ImageSignOptions, QrCodeSignOptions, TextSignOptions
from groupdocs.signature.domain import (
HorizontalAlignment, Padding, QrCodeTypes, SignatureFont, VerticalAlignment)
def sign_with_multiple_signatures_advanced():
with Signature("sample.pdf") as signature:
# Bold text signature at the top right, below the page header
text_options = TextSignOptions("Approved by John Smith")
font = SignatureFont()
font.family_name = "Arial"
font.size = 20
font.bold = True
text_options.font = font
text_options.width = 280
text_options.height = 40
text_options.vertical_alignment = VerticalAlignment.TOP
text_options.horizontal_alignment = HorizontalAlignment.RIGHT
text_options.margin = Padding(top=170, right=20)
# Stamp image in the bottom left corner
image_options = ImageSignOptions("stamp.png")
image_options.width = 100
image_options.height = 100
image_options.vertical_alignment = VerticalAlignment.BOTTOM
image_options.horizontal_alignment = HorizontalAlignment.LEFT
image_options.margin = Padding(left=20, bottom=20)
# QR code in the bottom right corner
qrcode_options = QrCodeSignOptions("https://www.example.com/verify")
qrcode_options.encode_type = QrCodeTypes.QR
qrcode_options.width = 100
qrcode_options.height = 100
qrcode_options.vertical_alignment = VerticalAlignment.BOTTOM
qrcode_options.horizontal_alignment = HorizontalAlignment.RIGHT
qrcode_options.margin = Padding(right=20, bottom=20)
# Sign the document with the list of signature options
list_options = [text_options, image_options, qrcode_options]
result = signature.sign("signed_multiple_advanced.pdf", list_options)
print(f"Signed with {len(result.succeeded)} signatures:")
for item in result.succeeded:
print(f" {item.signature_type.name}")
if __name__ == "__main__":

This guide demonstrates how to apply multiple types of electronic signatures (e.g., text, barcode, image) to a document using GroupDocs.Signature for Python via .NET. It explains how to combine different signature types, configure each one, and save the signed document with multiple signature styles.
You may easily run the code above and see the feature in action in our GitHub examples:
Along with the full-featured Python library, we provide simple but powerful free online apps.
To sign PDF, Word, Excel, PowerPoint, and other documents you can use the online apps from the GroupDocs.Signature App Product Family.
