Many users have downloaded an photo 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 defining how JPEG images is stored.
In practical terms, a JFIF file is a JPEG image. The .jfif extension occurs mostly after saving photos from some web 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 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.
