What is a .jp2 file?
A .jp2 file is a JPEG-2000 JP2 image. Its registered MIME type is image/jp2, which places it in the image family of formats.
JP2 stands for JPEG-2000.
JP2 is a binary format: the contents are not readable text, so opening it in a text editor shows scrambled characters.
The same format is also saved with the extension .jpg2.
