Many users have stored an image from the internet and found it appeared with a .jfif suffix in place of the standard .jpg, this happens often. JFIF — meaning JPEG File Interchange Format — is a format defining how JPEG image data is stored.
In practical terms, a JFIF photo is a JPEG photo. The .jfif suffix shows up primarily when saving files from specific 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 jfif to jpg no software 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 standard JPG file. In each case, the picture quality stays the same.
The quickest fix is a direct file rename. For Windows users, enable file extension visibility in File Explorer, click the .jfif image, select Rename and modify the extension to .jpg.
