WebP is an open-source format for image files, raster images. Created in 2010 by Google for web graphics in order to quickly upload images to web pages. This is the main advantage of WebP files. Compression of images in this format can go with or without loss, depending on what level of quality you want to achieve. Thus, lossless compression is 26% better than in PNG files. If quality loss is acceptable, then compression in WebP format is 25-34% better than in JPEG files. Full support for WebP is not yet available on Firefox, Internet Explorer, and Safari.
SVG is one of the formats of two-dimensional vector graphic files that are created on the basis of documents in XML format. The developer is Adobe Systems, and the name of the format is an abbreviation for Scalable Vector Graphics File. In the SVG format, not only two-dimensional vector images can be created, but also mixed vector-raster images. At the same time, SVG files are text files, and therefore they can be opened in most popular text editors. This extension is able to support both static and animated graphics. At the same time, when working with such files, editing occurs without loss of quality.
