Purpose of work: development of methods, algorithms, programs and graphic format of making progress compression of the coloured images is without losses. Work is directed on the decision of scientific and technical task of realization of making progress compression of the coloured images without losses by adaptation of existing and development of new methods and algorithms of previous transformations and code of bright components of pixels during their layer working. In the process of research the effective scientifically grounded chart of round of pixels is developed for realization of making progress hierarchical compression of images without losses. Application of this chart enables not only to accelerate decoding, when sizes of area of conclusion considerably less sizes images but also apply hierarchical predictors for prognostication of value of every element of attendant of pixels on all layers, beginning from the second. In direction of application of previous transformations mathematical models and effective methods and algorithms of processing of images are created by predictors for multiplying the level of their code surplus. The combined application of developed hierarchical predictors before the use of context-depended algorithm additionally diminishes the sizes of files of the compressed images on the average on 43 %. For realization a context-independent compression is select byte-oriented arithmetic code, as it accelerates decompression substantially. Keywords: progress compression of images, compression without losses, predictors, entropy.
