Have you ever downloaded an image from the web and noticed it downloaded with a .jfif file extension in place of the expected .jpg, this happens often. JFIF — which stands for JPEG File Interchange Format — is a standard defining the way JPEG photos is stored.
Simply put, a JFIF photo is a JPEG photo. The .jfif extension appears mainly after saving files from certain browsers, particularly if the image is delivered lacking a proper MIME type.
The .jfif extension became visible to everyday users because some web browsers — especially legacy versions of Internet Explorer — store JPEG photos with the correct .jfif file extension if the server fails to specify the file name.
Fixing this is straightforward: just rename the extension from .jfif to .jpg, or use a online converter to create a correctly named JPG file. In both cases, the image data does not change.
The simplest approach is a file extension change. For Windows users, turn on showing file extensions in File Explorer, right-click the .jfif file, choose Rename get more info and modify the extension to .jpg.
