The invention concerns a method for processing and storing bitonal video images, including digital scanned matrixes of white and black pixels belonging to a source image (IS), which has to be compressed in order to be transmitted and/or visualised with a reduced number of pixels. According to this method at least one matrix of the source image (IS), with preestablished sizes, is compressed in only one destination pixel with a level of grey corresponding to the ratio between the number of the black pixels and the number of the white pixels of the matrix. In this way the quality of the image is maintained and it is guaranteed its legibility.
