If you have ever saved an photo from the web and discovered it saved with a .jfif file extension rather than the usual .jpg, this is common. JFIF — short for JPEG File Interchange Format — is a specification defining how JPEG image data is stored.
Essentially, 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 specific MIME type.
JFIF files appeared to everyday users because some older more info browsers — especially older versions of Microsoft Edge — download JPEG photos with the technically accurate .jfif file extension if the server does not specify the filename.
Fixing this is straightforward: simply rename the file extension from .jfif to .jpg, or process it with a online converter to produce a standard JPG image. In each case, the picture quality does not change.
The quickest fix is a simple rename. On Windows, turn on showing file extensions in File Explorer, click the .jfif file, choose Rename and update the file extension to .jpg.
