Many users have stored an image from the web and noticed it appeared with a .jfif file extension in place of the standard .jpg, you are not alone. JFIF — short for JPEG File Interchange Format — is a specification defining the way JPEG images is saved.
Simply put, a JFIF image is a JPEG photo. The .jfif file type appears primarily while saving photos from some web browsers, especially if the image is delivered without a specific content-type header.
JFIF files appeared to everyday users because some older browsers — mainly older versions of certain browsers — store JPEG images with the proper .jfif file extension if the server omits the file name.
The solution is easy: either rename the extension from .jfif to .jpg, or process it with a online converter to generate a standard JPG image. In both cases, the photo content stays the here same.
The simplest approach is a direct file rename. On Windows, turn on showing file extensions in File Explorer, click the .jfif image, select Rename and update the file extension to .jpg.
