This short tutorial shows PDF and Python developers how to delete a digital signature from a PDF using the Aspose Cloud REST API. You will learn to upload the target PDF file to Cloud storage and remove its digital signature via the Python‑based SDK.

Prerequisite

• Create an account API credentials to delete a signature in a PDF
• Download the Aspose.PDF Cloud SDK for Python
• Set up a Python project with the above SDK

Steps to Delete a Signature from PDF using Python RESTful Service

1. Create an instance of PdfApi using your Client Secret and Client ID.
2. Define the name of the PDF and open it from the local file system.
3. Upload the local PDF file to Aspose Cloud using the UploadFile method.
4. Check if the signature field is valid and present in the uploaded PDF.
5. If the signature is valid, delete the signature field using DeleteField.
6. After deletion, download the modified PDF and save it locally.

These steps outline the process of removing a signature from a PDF with the Python REST interface. First, the code uploads a local PDF to Aspose Cloud, verifies the presence of a specific digital signature, and removes it if found. Then it downloads the updated PDF with the signature field removed and saves it locally.

Code to Delete Digital Signature from PDF using Python‑based API

The snippet demonstrates how to remove a digital signature from a PDF using the Python RESTful service. You may skip the verification steps if the signature field is already known. After the signature is removed, you can perform additional operations on the resulting PDF before downloading it to your local disk.
