NRW is a highly specialized raster image format that uses the Nikon Coolpix digital camera from the renowned Japanese manufacturer Nikon, as well as selected models of Nokia mobile phones. Full name - Nikon Raw Image File. The format is designed to create uncompressed digital photos in RAW format when shooting with a camera of a specified manufacturer. To open files of this format, special programs are needed, and to convert to another, more common, format, special converter programs are needed. The advantage of NRW files in saving data is in the version that the camera sensor detected; there is no compression or color correction.
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.
