In practical terms, a JFIF file is a JPEG image. The .jfif file type occurs mainly after saving images from certain browsers, mainly when files are is delivered lacking a specific MIME type.
JFIF files appeared to everyday users because some older browsers — especially older versions of Microsoft Edge — download JPEG images with the technically accurate .jfif file extension if 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 photo. Either way, the image data stays the same.
The easiest method is a direct file rename. On Windows, activate file extension display in File Explorer, right-click the .jfif image, select Rename and update the extension to .jpg.
