The WFX file type is primarily associated with WinFAX, a software application designed for sending, receiving, and managing faxes directly from a computer. Developed by Symantec, WinFAX was popular in the late 1990s and early 2000s for its ability to integrate fax communication with Windows operating systems, offering features like fax scheduling, fax broadcasting, and address book management. WFX files typically contain fax templates or fax document information used by the WinFAX program. Although WinFAX has been discontinued, WFX files can still be found within archives or older systems that utilized this software for fax communications.
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.
