Have you ever downloaded an picture from the online and noticed it appeared with a .jfif suffix in place of the usual .jpg, this is common. JFIF — short for JPEG File Interchange Format — is a specification defining how JPEG image data is stored.
In practical terms, a JFIF photo is a JPEG photo. The .jfif suffix shows up primarily when saving files from specific browsers, mainly if the image is delivered without a proper MIME type.
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 extension when the server omits the file name.
The fix is simple: just rename the file extension from .jfif to .jpg, or process it with a online converter to produce a standard JPG file. In each case, the picture quality does not change.
The quickest fix is a direct file rename. For Windows users, turn on file extension visibility in File Explorer, click the .jfif file, choose Rename and modify check here the extension to .jpg.
