This file extension appeared to everyday users as some older browsers — especially older versions of certain browsers — store JPEG images with the technically accurate .jfif file extension if the server does not specify the download name.
The solution is easy: either rename the extension from .jfif to .jpg, or use a converter tool to generate a correctly named JPG file. more info Either way, the image data stays the same.
The easiest method is a direct file rename. For Windows users, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the extension to .jpg.
