Sažetak
JPG is the most common format in digital photography today. In 2010 Google introduced WebP as the new optimal format for presenting photographs in the web environment, and the conversion of JPEG to WebP in Gmail, Picasa and Chrome services from 2013 is automatic and no more optional. Changes in colours and drawing sharpness of the image that occur in the JPEG - WebP conversion are analysed in the paper. The results point out changes in colours and the drawing sharpness of the image which are the outcomes of the JPG - WebP conversion and which can affect the technical, semantic and syntactic features of the photographs.
