CRW is a highly specialized graphic file format developed by the manufacturer of the famous Canon cameras. It is designed to record “raw” images captured by different models of a digital camera Canon. In its characteristics, it is very similar to another proprietary format of this developer - CR2. The main advantage of the CWR format is the preservation of the quality of the digital image as it comes from the camera matrix. The format also contains metadata, namely: conditions for photographing and fixing the image, default image processing settings, camera model.
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.
