8 Ιαν 2024 · To convert a PDF into Base64, we first need to get it in bytes and pass it through java.util.Base64.Encoder‘s encode method: byte[] inFileBytes = Files.readAllBytes(Paths.get(IN_FILE)); byte[] encoded = java.util.Base64.getEncoder().encode(inFileBytes);

import java.util.Base64; Then use the Base64 static methods as follows: byte[] encodedBytes = Base64.getEncoder().encode("Test".getBytes()); System.out.println("encodedBytes " + new String(encodedBytes)); byte[] decodedBytes = Base64.getDecoder().decode(encodedBytes); System.out.println("decodedBytes " + new String(decodedBytes));
21 Απρ 2021 · To encode a PDF file to Base64 you have to read all file bytes and encode them to Base64 using the Base64.Encoder class. Please keep in mind, that the example below prints the Base64 string to console, so use only small PDF files for tests or write the output into a text file.
Base64.encodeBase64 (bytes).toString () outputs [B@c163956. Here you are a minimal working implementation. File originalFile = new File("signature.jpg"); String encodedBase64 = null; try {. FileInputStream fileInputStreamReader = new FileInputStream(originalFile);
5 Ιαν 2024 · This article explained the basics of how to do Base64 encoding and decoding in Java. We used the new APIs introduced in Java 8 and Apache Commons. Finally, there are a few other APIs that provide similar functionality: jakarta.xml.bind.DataTypeConverter with printHexBinary and parseBase64Binary.
In this tutorial, we will walk through the process of converting a PDF file to a Base64 string in Java. We'll explore different ways to achieve this, including using built-in Java libraries and third-party libraries for more complex scenarios.
