JPEG is the most common and popular bitmap format. The form got its name from the name of the organization-developer Joint Photographic Experts Group. Files of this format are used today in all digital cameras and cameras. They have a good compression ratio and support 24-bit color depth. Since such compression significantly reduces image size with virtually no loss of quality, JPEG format is widespread on the Internet. However, the stronger the compression, the worse the quality. In addition, the JPEG format does not support the transparency option.
JPT is a file extension belonging to the JPEG 2000 bitmap file category (versions .jp2, .j2k, .jpt and others) and the JPEG 2000 file format. JPEG 2000 format is defined as a system for encoding and transmitting graphic raster files. It was developed by the Joint Photographic Experts Group (JPEG). It is approved by a series of ISO / ITU standards. The JPEG 2000 standard, which was designed from the very beginning to replace traditional JPEG, applies wavelet compression with and without loss. It gives an increased compression ratio and surpasses JPEG by all standards. The standard method for designating JPEG 2000 files is the .jp2 extension. However, other extensions are also used for this. In particular, .jpt. A .jpt file is a JPEG 2000 compressed image. It is saved in the JPT codestream version, where the name means “JPIP Tile-part”. This is a segmented part of JPIP, or the JPEG 2000 interactive protocol. This is the standard JPEG 2000 image streaming protocol. It is oriented to get maximum efficiency and quick access to graphic data. JPT is one of two standard streaming modes. The second mode is called JPP, JPIP Precinct.
