Have you ever stored an picture from the internet and noticed it downloaded with a .jfif file extension instead of the expected .jpg, this happens often. JFIF — which stands for JPEG File Interchange Format — is a specification that defines how JPEG images is encoded.
In practical terms, a JFIF file is a JPEG file. The .jfif file type occurs primarily when saving photos from specific browsers, mainly when the image was served without a specific file type header.
This file extension started showing to most people as some older browsers — mainly previous versions of certain browsers — download JPEG photos with the correct .jfif extension if the server does not specify the filename.
The fix is simple: either rename the extension from .jfif to .jpg, or process it with a online converter to create a properly labelled JPG photo. In each case, the picture quality does not change.
The simplest approach is a file extension change. For Windows users, click here enable file extension visibility in File Explorer, click the .jfif file, choose Rename and update the file extension to .jpg.
