If you have ever stored an image from the internet and found it downloaded with a .jfif file extension rather than the usual .jpg, this is common. JFIF — meaning JPEG File Interchange Format — is a format which defines the way JPEG images is saved.
Simply put, a JFIF file is a JPEG image. The .jfif extension occurs mostly after saving photos from some web browsers, particularly when the image was served with no a defined file type header.
The .jfif extension became visible to most people since some browsers — mainly previous versions of Internet Explorer — save JPEG photos with the technically accurate .jfif file extension if the server does not specify the download name.
Fixing this is straightforward: simply rename the extension from .jfif to .jpg, or use a converter tool to create a properly labelled JPG image. In both cases, the click here picture quality does not change.
The quickest fix is a direct file rename. For Windows users, enable file extension display in File Explorer, right-click the .jfif file, choose Rename and modify the extension to .jpg.
