Results of the study of a rare kaon decay K+→π+γγ at the NA62 experiment are presented. The model-independent branching fraction and decay spectrum are measured and compared with previous measurements and the prediction of the Chiral Perturbation Theory . Combined results of NA48/2 and NA62 data samples are also discussed
