Java Base64 Encode

Since Java 1.8 developers can use the Base64.Encoder class to encode data to Base64. This class provides several methods for encoding byte data to Base64 using algorithms specified in RFC 4648 and RFC 2045. In addition, Java provides the Base64.Decoder class for decoding Base64 values to byte data.

Example #1 (encode string):

import java.util.Base64;

class Base64Encode {
  public static void main(String[] args) {
    String str = "guru";
    String b64 = Base64.getEncoder().encodeToString(str.getBytes());
    System.out.println(b64); //-> "Z3VydQ=="
  }
}

  • rohit,
    Hi,

    I would like to get the java code implementation to convert svg image to base-64.

    Can you share the code snippet
    • Administrator,
      Hi! Since SVG is just XML (i.e. text data), the snippet on this page does exactly what you want.
      • rohit,
        Above code snippet works only when you extract buffered image from svg file and convert that to string and providing this string as input.

        I would like to see code which converts svg file to buffered image.

        I tried so many ways using batik jars but none is giving right output

        Its been a week I am struggling. It will be helpful if you can provide me working sample from svg file to buffered image
