Use of Image File Format WebP on Websites in Croatian top Domains

The paper deals with the use of WebP image format on web pages within the Croatian domain (.hr). Overview of usual image formats, JPEG, PNG, GIF and SVG, is given, but the emphasis is on the WebP format, which is the topic of the research. Its main features are described and how images are converted to WebP format from other formats, as well as the ways of using WebP format on web pages are listed. For the purposes of the research, a tool for collecting WebP images from web pages was developed. The mentioned tool found, identified and downloaded WebP images from the home pages of network sites within the .hr domain. Image data was stored in a database so that it could be analyzed further. The research showed that 1.04% (872 web pages) with the Croatian domain (.hr) use the WebP image file format. The largest number of web pages, 371 of them, use between two and five WebP images, while the smallest number of pages (ten of them) use over 50 WebP images. A manual review of web pages that have a larger number of WebP images leads to the conclusion that web shops mostly use this format. Furthermore, a review of WebP images showed that WebP is mostly used in cases where compression with data loss is suitable, for example, for photos.
