Abstract

WebP je format za digitalne slike predstavljen od strane Google-a u 2010. godini, njihov cilj je bio razviti format koji može osigurati manje datoteke bez značajnijeg gubitka na kvaliteti te pomoću njega učiniti web bržim i manjim. U teoretskom dijelu rada opisane su metode kompresije kako ovog formata tako i trenutno najkorištenijih formata u multimedijskom okruženju. Također je pisano o primjeni ovog formata, naime jedan od najvećih problema s kojim se suočava WebP format jest njegova primjena i podržanost od strane korisnika. U istraživanju se krenulo od pretpostavke da ovaj format nudi bolju kompresiju, bez gubitaka na kvaliteti digitalne fotografije, te je rađeno u tri djela. Kroz analizu učinkovitost kompresije ovoga formata u usporedbi j JPG i PNG formatima, te koliki je utjecaj kompresije na kvalitetu slike, a zatim i primjenu ovog formata. Rezultati koji su dobiveni analizom kompresije su obećavaju, moguće je dobiti digitalne fotografije znatno manje veličine, međutim ovaj format se nije iskazao u usporedbi kvalitete dobivenih fotografija kao ni u primjeni na webu.

Abstract in english:	WebP is a format for digital images introduced by Google in 2010, their aim was to develop a format that can provide smaller files without significant loss of quality and make web faster and smaller. In the theoretical part of the paper, we have described the methods of compression that this format uses, and is currently the most usedformats in the multimedia environment. It is also written on a subject applying this format on web, namely, one of the biggest problems facing the WebP format is its application and support by the user. The assumption of the study was that this format offers better compression, without loss of quality digital photography, and was conducted in three parts. Through an analysis of the effectiveness of compression of this format compared with JPG and PNG formats, the image quality, and then the application of this format. Results obtained by analyzing compression are promising, it is possible to get digital images much smaller size, but this format does not show a significantly better result in comparison with other formats as well as in the application on the web.
