Delete PDF Metadata with Python REST API

This guide shows how to Python developers can programmatically remove PDF metadata using the Aspose.PDF Cloud REST API, leveraging the official Python SDK to delete custom document properties in a few simple steps. For more information about the PDF format, see the PDF file info page.

Steps to Clean Metadata from PDF with Python REST Interface

  1. Instantiate the PdfApi object by providing your API key and App SID.
  2. Load the target PDF file into a Document object that contains custom properties.
  3. Call the DeleteProperties() method to remove the custom properties.
  4. If needed, retrieve the remaining properties with pdfApi.get_document_properties().
  5. Download the updated PDF file.

The steps above outline the creation of a PDF properties remover using the Python Low‑Code API. First upload the PDF with upload_file(), then invoke delete_properties() to clear the custom entries. Built‑in properties cannot be removed directly, but you can clear their values by using pdfApi.put_set_property() and setting the value to null.

Code to Strip PDF Metadata with Python RESTful Service

The snippet demonstrates how to clean PDF metadata with the Python‑based API. To add a new custom property, use pdfApi.put_set_property()—the method will update the value if the property exists or create it otherwise. To list the current properties, call get_document_properties() and iterate over the response.

This article covered deleting all custom properties from a PDF file. For adding or updating metadata, refer to the article on Update PDF metadata with Python REST API.
