Have you ever downloaded an picture from the online and noticed it appeared with a .jfif suffix in place of the usual .jpg, this happens often. JFIF — short for JPEG File Interchange Format — is a specification defining how JPEG image data is stored.
Essentially, a JFIF photo is a JPEG file. The .jfif suffix appears primarily while saving files from some web browsers, especially if 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 more info the file extension from .jfif to .jpg, or process it with a online converter to produce a standard JPG file. 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, select Rename and modify the extension to .jpg.
