Many users have 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, especially when the image was served with no a defined file type header.
The .jfif extension became visible to most people since some browsers — particularly previous versions of Internet Explorer — save JPEG files with the correct .jfif extension when websites fails to specify the filename.
The fix is simple: just rename the file extension from .jfif to .jpg, or process it with a online converter to produce a correctly named JPG photo. Either way, the image data stays the same.
The easiest method is a direct file rename. For more info Windows users, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the extension to .jpg.
