Many users have stored an image from the web and discovered it saved with a .jfif file extension rather than the usual .jpg, this is common. JFIF — which stands for JPEG File Interchange Format — is a standard which defines the way JPEG photos is stored.
In practical terms, a JFIF file is a JPEG photo. The .jfif file type occurs mainly after saving photos from certain browsers, particularly when the image comes with no a defined file type header.
The .jfif extension became visible to most people since some web browsers — particularly older versions of certain browsers — store JPEG images with the proper .jfif file extension when the server omits the file name.
The solution is easy: just rename the extension from .jfif to .jpg, or run it through a conversion tool to create a properly labelled JPG image. In both cases, the photo content remains unchanged.
The simplest approach is a file extension change. On here Windows, activate showing file extensions in File Explorer, click the .jfif file, choose Rename and update the file extension to .jpg.
