Many users have stored an image from the web and discovered it saved with a .jfif file extension rather than the usual .jpg, this is common. JFIF — short for JPEG File Interchange Format — is a standard that defines how JPEG image data is encoded.
Essentially, a JFIF photo is a JPEG file. The .jfif suffix shows up primarily when saving files from specific browsers, especially if the image was served without a proper file type header.
This file extension became visible to everyday users as some web browsers — particularly 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 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 website .jfif image, select Rename and modify the extension to .jpg.
