If you have ever stored an picture from the online and noticed it appeared with a .jfif file extension rather than the usual .jpg, this is common. JFIF — short for JPEG File Interchange Format — is a specification defining how JPEG image data is stored.
Simply put, a JFIF file is a JPEG photo. The .jfif suffix appears mostly after saving photos from specific browsers, especially when the image comes without a proper content-type header.
JFIF files started showing to everyday users because some older browsers — mainly older versions of Internet Explorer — download JPEG photos with the proper .jfif file extension when the server does not specify the download name.
The solution is easy: either rename the file extension from .jfif to .jpg, or run it through a online converter to generate a correctly named JPG image. In each case, the picture quality stays the same.
The quickest fix is a direct file rename. here On Windows, activate file extension visibility in File Explorer, click the .jfif image, select Rename and update the extension to .jpg.
