If you have ever downloaded an photo from the online and noticed it appeared with a .jfif suffix rather than the usual .jpg, this is common. 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 shows up primarily while saving files from specific browsers, especially if the image was served with no a proper file type header.
This file extension became visible to most people since some web browsers — particularly previous versions of Internet Explorer — save JPEG files with the proper .jfif extension when websites fails to specify the filename.
The fix is simple: just rename the file extension from .jfif to .jpg, or run it through a online click here converter to produce a standard JPG image. In both cases, the picture quality does not change.
The quickest fix is a simple rename. On Windows, turn on showing file extensions in File Explorer, click the .jfif file, choose Rename and change the file extension to .jpg.
