If you have ever saved an photo from the web and discovered it saved with a .jfif file extension rather than the expected .jpg, you are not alone. JFIF — which stands for JPEG File Interchange Format — is a standard that defines the way JPEG photos is saved.
Simply put, a JFIF image is a JPEG image. The .jfif extension appears mostly while saving photos from some web browsers, particularly when the image comes lacking a defined content-type header.
The .jfif extension started showing to regular users since some browsers — mainly legacy versions of Internet Explorer — save JPEG files with the correct .jfif extension when websites fails to specify the filename.
Fixing this is straightforward: just rename the file extension from .jfif to .jpg, or process it with a online converter to produce a standard JPG image. 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.
