If you have ever downloaded an picture 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 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, 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 previous 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, more info or run it through a conversion tool to create a properly labelled JPG image. In both cases, the photo content remains unchanged.
The simplest approach is a file extension change. On Windows, activate showing file extensions in File Explorer, right-click the .jfif image, select Rename and update the file extension to .jpg.
