This quick tutorial guides us on how to transform PDF A to PDF in Java for removing long-term preservation restrictions. It has the details to set the IDE for development, a list of simple tasks to accomplish the task, and a runnable sample code to develop PDF A to PDF converter in Java. This code can be used in any of the platforms having a Java runtime environment and save the output in any of the supported formats.

Steps to Convert from PDF A to PDF in Java

1. Set the IDE for using Aspose.PDF for Java to write a PDF/A converter
2. Open the PDF file using the Document class for removing long-term preservation
3. Check the PDF A compliance before removing the compliance
4. Call the removePdfaCompliance() method to remove the constraints
5. Check the PDF A compliance again to confirm the removal of compliance
6. Save the output PDF file after changing the PDF/A-compliant features

These steps encompass the procedure to change PDF A to PDF in Java. The simplest tasks are to load the PDF file, call the removePdfaCompliance() method, and save the output PDF file. However, for the sake of optional confirmation, Document.isPdfaCompliant property is used to display the status before and after calling the method.

Code to Transform PDF A to PDF in Java

The aforementioned piece of code demonstrates the process to convert PDF A to PDF in Java. When you run this code, the self-containment and device independence features are removed and fonts can be linked instead of embedded into the PDF file. You may also encrypt the PDF file that was not allowed earlier due to PDF/A compliance.
