The XWD (X Windows Dump) image file format is a native graphic format associated with the X Window System, which is a windowing system for bitmap displays commonly used in UNIX and Linux environments. An XWD file is essentially a dump or snapshot of what is being displayed on a screen or part of it at a given moment. It stores image data in an uncompressed form, including the header information that contains details about the image's size, color, and format.
