Many users have downloaded an image from the internet and discovered it saved with a .jfif file extension rather than the usual .jpg, this happens often. JFIF — meaning JPEG File Interchange Format — is a format which defines the way JPEG photos is saved.
Simply put, a JFIF image 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 started showing to most people since some browsers — mainly legacy versions of Microsoft Edge — download JPEG photos with the technically accurate .jfif file extension when the server omits the file name.
The fix is simple: just rename the file extension from .jfif to .jpg, or process it with a converter tool to generate a properly labelled JPG photo. In both cases, the photo content does not change.
The quickest fix is a direct file rename. For website Windows users, activate showing file extensions in File Explorer, click the .jfif file, select Rename and modify the extension to .jpg.
