Convert kwd to avif

What is the difference between .kwd and .avif?

Description: The kwd file type is associated with KWord, a word processing and desktop publishing application that was part of the KOffice suite primarily for Linux and UNIX-like operating systems. KWord documents, denoted by the .kwd extension, incorporate text, images, and formatting into a single file, allowing users to create professional-looking documents. KWord supported a wide range of features including templates, styles, frames, and more, making it a versatile tool for various document creation needs.; It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images. Also, it contains both the image sequences and image items. The only pitfall is that a few applications support it.
