Many users have stored an image from the internet and found it downloaded with a .jfif extension instead of the standard .jpg, this happens often. JFIF — meaning JPEG File Interchange Format — is a format which defines the way JPEG images is stored.
In practical terms, a JFIF file is a JPEG photo. The .jfif file type appears mostly after saving images from specific browsers, especially if the image was served with no a proper file type header.
This file extension appeared to everyday users as some older browsers — especially older versions of Microsoft Edge — download JPEG photos with the technically accurate .jfif file extension if the server fails to specify the file name.
Fixing this is straightforward: just rename the file extension from .jfif check here to .jpg, or process it with a online converter to produce a standard JPG photo. In both cases, the picture quality does not change.
The simplest approach is a file extension change. For Windows users, activate file extension display in File Explorer, click the .jfif file, choose Rename and modify the extension to .jpg.
