JPF is a raster image category file format that is the successor to the .JPEG image format. Like some other file name extensions (.jpx, .jp2, .j2k), the .jpf extension refers to the JPEG 2000 image format. It is needed to designate the JPEG 2000 Image file type. And JPEG 2000 files are an international standard (ISO / IEC 15444) bitmap format. It was developed by the Joint Photographic Experts Group, JPEG. It serves as a good replacement for the JPEG standard, which is older, but, as before, is in demand and widespread. Compared to JPEG in JPF format, wavelet compression is used, due to the alpha channel transparency is supported, as well as a variety of color models. Also, compared to JPEG, this format provides better scalability of images, provides the ability to achieve smaller file sizes and have a higher level of quality. The format is able to combine compression with losses and without losses. Provides support for image transparency and additional metadata information. It can be viewed in QuickTime Player 7, as in recent versions of Photoshop, provided that the JPEG2000.8bi plugin is installed. Many images also have the extension .JP2 or .JPX.
SVG is one of the formats of two-dimensional vector graphic files that are created on the basis of documents in XML format. The developer is Adobe Systems, and the name of the format is an abbreviation for Scalable Vector Graphics File. In the SVG format, not only two-dimensional vector images can be created, but also mixed vector-raster images. At the same time, SVG files are text files, and therefore they can be opened in most popular text editors. This extension is able to support both static and animated graphics. At the same time, when working with such files, editing occurs without loss of quality.
