Download of OpenJPEG 2.3.0 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available.
Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free Mac application was originally developed by Université de Louvain. OpenJPEG for Mac relates to Design & Photo Tools.
From the developer:
OpenJPEG is an open-source JPEG 2000 codec written in C language. It has been developed in order to promote the use of JPEG 2000, a still-image compression standard from the Joint Photographic Experts Group (JPEG). The library has been created and is still maintained by the Image and Signal Processing Group.
You may want to check out more software for Mac, such as Cuadro or Resize Now, which might be similar to OpenJPEG.
