Mac solutions (two of many): Preview & Graphics Converter

   • With the file open, select the Export option, and then save the duplicate image as a TIFF or JPEG.

2. GraphicConverter is another option; while not free it is a fairly inexpensive tool for the batch conversion of image files.

GraphicsMagick supports JPEG2000 and many other formats, and command-line conversion is easy:
