JPM (JPEG 2000 compound image) is the image format defined by Part 6 of the JPEG 2000 standard (ISO/IEC 15444-6). JPM is an extension to the JP2 format, and was developed for multi-page documents with multiple objects per page. Like JPX, it also supports a number of alternative compression methods (JPEG, JBIG, JPEG-LS, T.45 Run-length colour encoding, and for some purposes Modified Huffman, Modified READ, Modified Modified READ, JBIG2).
