If you have ever downloaded an picture from the online and noticed it appeared with a .jfif suffix 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.
Simply put, a JFIF file is a JPEG image. The .jfif file type occurs mostly after saving photos from some web browsers, particularly when the image comes with no a defined file type header.
The .jfif extension became visible to most people since some web browsers — particularly previous versions of certain browsers — store JPEG images with the proper .jfif 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, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the extension to .jpg.
