The CALS Raster Graphic File, having the extension .cals, is a type of image file format primarily used for the storage and exchange of digital images, especially in the context of technical and engineering documents. Developed in the mid-1980s by the United States Department of Defense, the CALS format was part of an initiative to standardize electronic document management and interchange, particularly for military and government applications.
WebP Image (WEP) is an image file format developed by Google in 2010. It is based on the VP8 video format and is used to create smaller, higher quality, and lossy compressed images. It is supported by most major web browsers and is commonly used for web graphics.
