The purpose of the study was to determine the specifics of the functioning of convergent journalism of Ukrainian online media and its role in ensuring effective communication in the context of military conflict. The research methodology combined comparative, contextual, and structural functional analysis of open sources, industry monitoring, and survey results. The findings showed that the war accelerated the process of convergence, transforming it from an innovative practice to the normal functioning of the media, while changing the nature of the professional roles of journalists, combining the functions of a reporter, analyst, and multimedia producer. It was found that Telegram became the dominant channel of operational information, YouTube serves as contextualisation and explanation of events, and websites provide archiving and verification of analytical content. The analysis showed that multimedia formats have increased interactivity and audience engagement, while creating mechanisms for cognitive protection against misinformation. It was investigated that professional standards of journalism have undergone adaptation, in particular, a shift from the traditional principle of verification before publication to operational publication with subsequent verification and the use of open source tools to confirm facts. The results of the study showed that convergent journalism of Ukrainian online media takes place to ensure information stability and effective management of public communication during the war. It was proved that the transformation of professional standards and platform differentiation of media created a comprehensive system of interaction between editorial offices and the audience. The practical significance of the results obtained lies in their orientation to editorial teams, media experts, and public communication bodies to improve the effectiveness of information policy and media security in crisis conditions
