The paper discusses individual advantages and benefits that the digitalization of criminal procedures can provide. The forms of positive use of digital technologies in practice and the possibility of expanding their use are shown. It is proposed to do this by experimental implementation: a) to introduce them in parallel, along with the traditional ones, or b) to use them completely for different stages of the procedure that are most suitable for formalization and programming. There are three groups of criteria that need to be taken into account: objective characteristics of the nature of criminal procedural relations; the possibility/impossibility of formalization of requirements and procedures; the ability to strengthen, rather than reduce the guarantees of human rights, the reliability of the results of knowledge and justice of law enforcement acts. For a systematic transition to these technologies, it is impossible not to take into account that «human abilities» in criminal procedure can not always be formalized to the extent of their replacement by digital technologies.
