If you have ever saved an photo from the web and discovered it saved with a .jfif extension instead of the expected .jpg, you are not alone. JFIF — which stands for JPEG File Interchange Format — is a format which defines the way JPEG images is saved.
In practical terms, a JFIF file is a JPEG image. The .jfif file type occurs mainly after saving images from certain browsers, mainly when files are is delivered without a specific MIME type.
This file extension appeared to everyday users as some web browsers — especially older versions of certain browsers — store JPEG images with the proper .jfif extension when the server omits the file name.
The fix is simple: just rename the extension from .jfif to .jpg, or run it through a conversion tool to create a standard JPG image. In both cases, the photo content does not change.
The quickest fix is a simple rename. On Windows, turn on file extension visibility in File Explorer, click the .jfif file, more info choose Rename and change the file extension to .jpg.
