View Metadata of PDF with Java REST API

PDF Java developers can quickly retrieve document metadata using the Aspose.PDF Cloud REST API. This guide walks you through setting up the Java SDK, uploading a PDF file, and calling the GetDocumentProperties endpoint to list all available properties or fetch a specific one such as Producer. For more details on the PDF format, see the PDF file info page.

Prerequisite

Steps to Access PDF Metadata with Java Low Code API

  1. Configure the PdfApi class object with your Client ID and secret.
  2. Upload the source PDF file that you want to inspect.
  3. Call the GetDocumentProperties() method to retrieve the document’s properties.
  4. Iterate through the properties returned in the API response.
  5. Print all properties or a selected subset to the console.

The steps above illustrate how to check PDF metadata with Java Low Code API: initialize PdfApi, upload the PDF, invoke GetDocumentProperties(), and process the response. You can choose to display every property or filter for specific ones based on your needs.

Code to Read Metadata from PDF with Java-based API

The sample demonstrates how to see PDF metadata with Java-based API. It shows how to locate a property by name—e.g., the “Producer” field—and how to retrieve either that single property or the full set of metadata from the uploaded PDF.

If you need to modify PDF metadata, see the companion article on Update PDF metadata with Java REST API.
