Many users have 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 saved.
In practical terms, a JFIF file is a JPEG image. The .jfif file type occurs mainly when saving images from certain browsers, mainly when files are is delivered without a specific MIME type.
JFIF files appeared to everyday users as some older browsers — especially older versions of certain browsers — store JPEG images with the proper .jfif file extension when the server omits the file name.
The solution is easy: either rename the extension from .jfif to .jpg, or use a converter tool to create a properly labelled JPG photo. Either way, the image data stays the same.
The easiest method is a file extension change. On Windows, activate file extension display in File Explorer, right-click the .jfif image, select Rename website and update the extension to .jpg.
