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, especially if the image is delivered without a proper MIME type.
This file extension appeared to everyday users as some web browsers — especially older versions of certain browsers — store JPEG images with the proper .jfif file extension when the server does not specify the download name.
The solution is easy: either rename the extension from .jfif to .jpg, or use a converter tool to generate a properly labelled JPG photo. Either way, the image data stays the same.
The easiest method is a direct file rename. click here On Windows, enable file extension display in File Explorer, right-click the .jfif image, select Rename and modify the extension to .jpg.
