JP2 is a bitmap image format. The JP2 format, i.e. JPEG 2000 image, was developed by the Joint Photographic Experts Group. The JP2 file can be in the form of a photograph, drawing, digital fax, etc. File type: JPEG 2000 Core Image File. JPEG 2000 is the patent-pending bitmap image format. It has been licensed free of charge, and now it is an international standard (ISO / IEC 15444-1: 2004). Compared to the previous JPEG-1 standard, JPEG 2000 uses a completely different method to compress data (wavelet transform, wavelet transform). This method generally ensures higher image quality. It also gives a more compact file size. The JP2 format has a lot in common with the JPEG format, which is now especially popular. However, it differs in that it uses wavelet transform technology for compression, and discrete cosine transform has found application in JPEG. Using the first technology, you can get a better image, even when the file size is relatively smaller. There are also JP2 files with the extensions .J2K, JPF, MJ2, JPX and JPM. In order to open a file of this format, that is, to edit, use programs such as Mozilla Firefox, Adobe Photoshop, ACD Systems ACDSee, Google Chrome.
TIFF is a format that allows you to store raster graphics with tags. It was developed by Aldus Corporation in conjunction with Microsoft so that it can be used with PostScript. Aldus Corporation owns specifications. Subsequently, this company merged with Adobe Systems. It is she who now owns the copyright to these specifications. Typically, TIFF files (Tagged Image File Format) are with the extension .tiff or .tif. Aldus was specifically engaged in the development of the format in order to achieve the preservation of scanned images. The popularity of TIFF can be explained by the fact that it is preferred in order to store images that have a large color depth. The format is used to send faxes, scan, recognize texts. It is widely supported in the printing industry. TIFF was chosen as the main graphic format of the NeXTSTEP operating system. Then from this system TIFF support migrated to Mac OS X. At first, the format supported lossless compression. Then it was supplemented in order to support lossy compression in JPEG format. We emphasize that the maximum weight of a document, if stored in this form, is no more than 4 GB. To open a TIFF file larger than 2 GB, you must run Photoshop CS.
