*We recommend Java 1.6 or Java 1.8 for our Qoppa’s PDF library and component products because:

  • Qoppa’s development team environment is Java 1.6, so we can stay compatible with that version
  • PDF Studio, Qoppa’s advanced Desktop PDF editor built on top of jPDFEditor, is shipped with Java 1.8 and used by thousands of users every day.
