title: After encoding data size is increasing
body: <p>I am having a text data in XML format and it's length is around 816814 bytes. It contains some image data as well as some text data. 
  We are using ZLIB algorithm for compressing and after compressing, the compressed data length is 487239 bytes. </p>
  
  <p>After compressing we are encoding data using BASE64Encoder. But after encoding the compressed data, size is increasing and length of encoded data is 666748 bytes. </p>
  
  <p>Why, after encoding data size is increasing? Is there any other best encoding techniques? </p>
