Have you ever downloaded an picture from the online and noticed it appeared with a .jfif extension instead of the standard .jpg, this happens often. JFIF — meaning JPEG File Interchange Format — is a format which defines the way JPEG images is saved.
Simply put, a JFIF image is a JPEG image. The .jfif extension occurs mostly after saving photos from certain browsers, particularly when files are comes lacking a specific content-type header.
JFIF files started showing to regular users because some older browsers — mainly legacy versions of Microsoft Edge — download JPEG photos with the technically accurate .jfif file extension if the server does not specify the download name.
Fixing this is straightforward: simply rename the extension from .jfif to .jpg, or use a converter tool to generate a correctly named JPG photo. Either way, the image data stays the same.
The easiest method is a direct file rename. For Windows users, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the extension to .jpg.
