You can also use Apache Commons Codec (http://commons.apache.org/codec/)

String example = "SGVsbG8gV29ybGQ="
byte[] decoded = org.apache.commons.codec.binary.Base64.decodeBase64(example .getBytes());

Thank you buddy. The Java's stock parser was not working for me. This worked. :) – systemhalted Jun 10 '15 at 14:06

Since Java 8 you can use the built in `java.util.Base64`. – karl Feb 22 '17 at 08:59

import sun.misc.BASE64Decoder;

BASE64Decoder decoder = new BASE64Decoder();
byte[] imageByte = decoder.decodeBuffer(imageData);

Where imageData is String containing Base64 data.

Your program becomes non-portable because sun.misc package is not part of Java SE API and is not guaranteed to be present in the standard library. – Igor Vuković Oct 25 '16 at 12:46
