If you have ever downloaded an picture from the online and noticed it appeared with a .jfif suffix in place of the standard .jpg, this happens often. JFIF — meaning JPEG File Interchange Format — is a format which defines the way JPEG images is saved.
Simply put, a JFIF image is a JPEG image. The .jfif extension appears mostly while saving photos from some web browsers, especially if the image was served without a specific MIME type.
JFIF files appeared to regular users because some older browsers — especially legacy versions of Microsoft Edge — save JPEG files with the correct .jfif extension when websites fails to specify the filename.
Fixing this is straightforward: simply rename the file extension from .jfif to .jpg, or process it with a online converter to produce a standard JPG file. In each case, the picture quality does not change.
The quickest fix is a simple rename. For Windows users, turn on file extension visibility in File Explorer, click the .jfif file, choose Rename and change the file extension to .jpg.
