Convert xwd to azw3

What is the difference between .xwd and .azw3?

Description: 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.; An AZW3 file is an eBook created in the Kindle Format 8 (KF8), Amazon's successor to the .AZW format. It supports newer features such as HTML5 and CSS3 support as well as many other formatting capabilities. AZW3 files often include DRM protection and are used as the download format for many Amazon eBooks.
