Many users have downloaded an picture from the web and found it appeared with a .jfif file extension instead of the standard .jpg, this is common. JFIF — which stands for JPEG File Interchange Format — is a specification which defines the way JPEG image data is saved.
Essentially, a JFIF file is a JPEG image. The .jfif suffix occurs mostly while saving files from certain browsers, particularly when files are is delivered lacking a specific content-type header.
The .jfif extension became visible to everyday users as some web browsers — particularly older versions of certain browsers — store JPEG files with the correct .jfif file extension if the server omits the filename.
The fix is simple: just rename the extension from .jfif to .jpg, or run it through a online converter to generate a properly labelled JPG file. Either way, the photo content stays the same.
The simplest approach is a simple rename. On Windows, enable file extension display in File Explorer, click the .jfif file, choose Rename and update the extension to .jpg.
