Have you ever downloaded an picture from the internet and found it downloaded with a .jfif extension instead of the expected .jpg, you are not alone. 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 primarily while saving files from specific browsers, especially if the image was served without a proper MIME type.
This file extension 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 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 correctly named JPG file. In each case, the image data stays the same.
The easiest method is a direct file rename. For Windows users, turn on file extension visibility in File Explorer, click the .jfif file, choose Rename and change the file extension to .jpg.
