Description
The Sun Rasterfile, identified by the extension .rast, is a bitmap image file format originally developed for use on SunOS by Sun Microsystems. It is designed to store color and monochromatic raster images, such as scanned photographs and digital artwork. The format supports various color depths, including 1, 8, 24, and 32 bits per pixel, allowing for a range of color representations from simple black and white to full true color images. Despite its origins on Sun systems, the format can be used on various platforms and is supported by a variety of image editing and viewing software.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
