This article explains how to convert a PDF to Base64 in Java. It includes setup guidelines, sequential steps, and an example code to convert a PDF to Base 64 in Java. Furthermore, you can take advantage of different classes and methods to refine the PDF processing workflow according to your requirements.

Steps to Render PDF to Base64 in Java

1. Set up the environment with Aspose.PDF to convert PDF into Base64 format
2. Load the PDF document using the Document class to encode it into base64
3. Initialize a ByteArrayOutputStream and generate a byte array containing the PDF content with the encodeToString method
4. Transform the byte array into a Base64 string and obtain the output

These guidelines outline the approach to convert PDF file to base64 in Java. Meanwhile, you can extend it further by reading the PDF file from a stream, processing only chosen pages, or applying other personalized configurations. In addition, the result can be retrieved as a Base64 encoded string or even transformed into an image.

Code to Convert PDF to Base64 in Java

The shared code snippet demonstrates how to convert PDF to base 64 in Java. You just need to load the PDF file and encode it into base64 with a memory stream. After that, the Base64 string can be obtained either on the console or stored in a file, based on your needs.
