Many users have saved an photo from the web and discovered it saved with a .jfif file extension rather than the expected .jpg, this is common. JFIF — which stands for JPEG File Interchange Format — is a standard that defines the way JPEG photos is encoded.
Essentially, a JFIF image is a JPEG file. The .jfif suffix appears mostly while saving files from some web browsers, especially if the image was served with no a proper file type header.
This file extension became visible to most people as some web browsers — particularly older versions of certain browsers — store JPEG images with the proper .jfif file extension when the server omits get more info the file 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 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.
