This short tutorial describes the step-by-step process to extract metadata from PDF using Java. We will use one of the best metadata extractor API for fetching the metadata from the PDF document. Further, you will learn how to write the code to create functionality to get metadata from PDF in Java. Below are the detailed instructions and a sample code for extracting metadata from documents.

Steps to Extract Metadata from PDF using Java

1. Install GroupDocs.Parser for Java from the Maven repository in the Java project to extract metadata from PDF document
2. Import essential classes for developing the functionality for extracting metadata from PDF document
3. Create an instance of the Parser class and pass the source PDF file to its constructor
4. Call the getMetadata method and obtain a collection of PDF document metadata objects
5. Finally, iterate through the collection and display metadata names and values

We have listed the stepwise instructions to get PDF metadata using Java. You have to follow these points in a sequence for extracting metadata from the PDF document and you do not need to set up any additional software for it. These steps can be used on any operating system including MS Windows, Linux, and Mac OS.

Code to Extract Metadata from PDF using Java

In the above example, we have developed the Java PDF metadata capability. As you can see, the Parser class is used for loading the input PDF document for getting the metadata. After that, we have called the getMetadata method for collecting the metadata and iterating over it for displaying the name and value of the metadata. You can also extract metadata from various document formats such as DOCX, XLSX, PPTX, MSG, EML, EPUB, and many more.

We have discussed the detailed procedure to extract metadata from PDF in Java. Recently, we published an article on extracting metadata from Word document in Java, have a look at how to Extract Metadata from Word Document using Java guide for more information.
