If you have ever downloaded an photo from the web and discovered it saved with a .jfif file extension rather than 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 saved.
Simply put, 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 photos with the technically accurate .jfif file extension if the server does not specify the download name.
Fixing this is straightforward: simply rename the extension from .jfif to .jpg, or use a converter tool to generate a correctly named JPG file. Either way, the image data stays the same.
The easiest method is a direct file rename. For Windows users, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the extension to .jpg.
