If you have ever saved an photo from the web and discovered it saved with a .jfif file extension rather than the usual .jpg, this is common. JFIF — short for JPEG File Interchange Format — is a standard that defines how JPEG photos is encoded.
Essentially, a JFIF image is a JPEG file. The .jfif extension appears mostly while saving photos from some web browsers, particularly when the image comes lacking a defined content-type header.
JFIF files started showing to regular users because some older browsers — mainly legacy versions of Microsoft Edge — download 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 file extension from .jfif to .jpg, or process it with a online converter to generate a correctly named JPG file. In each case, the picture quality stays the same.
