Have you ever stored an image from the internet and found it downloaded with a .jfif extension in place of the standard .jpg, this happens often. JFIF — meaning JPEG File Interchange Format — is a format which defines the way JPEG images is stored.
In practical terms, a JFIF file is a JPEG photo. The .jfif file type shows up mainly when saving images from certain browsers, mainly when files are is delivered lacking a specific MIME type.
JFIF files appeared to everyday users as some older browsers here — especially older versions of certain browsers — store JPEG images with the technically accurate .jfif file extension if the server does not specify the download name.
The solution is easy: either rename the extension from .jfif to .jpg, or use a converter tool to generate a properly labelled JPG photo. Either way, the image data stays the same.
The easiest method is a file extension change. On Windows, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the extension to .jpg.
