Have you ever downloaded an picture from the internet and found it downloaded with a .jfif file extension rather than the expected .jpg, this is common. JFIF — short for JPEG File Interchange Format — is a standard that defines how JPEG image data is encoded.
Essentially, a JFIF photo is a JPEG file. 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 appeared to everyday users as some older browsers — especially get more info older versions of Microsoft Edge — download JPEG photos with the technically accurate .jfif file extension if the server fails to 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 both cases, 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.
