The RPNM file format, standing for "Portable Image," is a variant of the PNM file format used for storing images. It is designed to be a simple, yet flexible format that can accommodate various types of image data, including grayscale, black and white, and color. RPNM files can be easily transferred between different platforms and software applications due to their simplicity and portability. They are often used in applications and situations where minimal processing and compatibility across different systems are crucial.
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.
