Have you ever stored an image from the web and found it saved with a .jfif extension in place of the usual .jpg, you are not alone. JFIF — meaning JPEG File Interchange Format — is a specification that defines the way JPEG image data is stored.
Simply put, a JFIF photo is a JPEG image. The .jfif suffix occurs primarily after saving files from certain browsers, mainly when the image was served without a specific file type header.
JFIF files started showing to most people as some browsers — particularly legacy versions of Internet Explorer — store JPEG images with the technically accurate .jfif extension if the server fails to specify the file name.
Fixing this is straightforward: either rename the extension from .jfif to .jpg, or process it with a converter tool to create a properly labelled JPG image. In each case, the image data stays the same.
The easiest method is a file extension change. For Windows users, enable file extension display in File Explorer, click the .jfif image, select Rename and change the here extension to .jpg.
