What is the difference between .x11 and .webp?

Description: The X11 file type, associated with the X Windows System, is a format designed to contain screen or window dumps (screenshots) from the X Window System, a windowing system for bitmap displays common on UNIX-like operating systems. These dumps are essentially captures of the graphical output of applications running within the X environment, saved in a format that can be viewed or analyzed later. The X Window System serves as the foundational graphical interface for many Linux and UNIX systems, facilitating a wide range of graphical applications. X11 files enable users to save and share the state of a graphical interface at a specific point in time, useful for documentation, debugging, or graphic design purposes.; 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.
