Have you ever stored an photo from the web and noticed it appeared with a .jfif extension rather than the usual .jpg, this happens often. JFIF — which stands for JPEG File Interchange Format — is a standard that defines how JPEG images is saved.
Essentially, a JFIF photo is a JPEG photo. The .jfif file type occurs primarily after saving photos from some web browsers, mainly when files are was served without a specific content-type header.
This file extension appeared to regular users since some older browsers — especially legacy versions of certain browsers — store JPEG photos with the correct .jfif extension when the server does not specify the filename.
The fix is simple: just rename the extension from .jfif to .jpg, or use a online converter to produce a standard JPG image. In both cases, the photo content remains unchanged.
The easiest method is a direct file rename. For Windows users, enable file extension visibility in File Explorer, click the .jfif file, choose Rename and check here change the file extension to .jpg.
