If you have ever downloaded 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 encoded.
In practical terms, a JFIF photo is a JPEG photo. The .jfif file type shows up mainly when saving images from certain browsers, mainly when files are comes lacking a defined content-type header.
The .jfif extension started showing to most people since some browsers — mainly previous versions of Internet Explorer — save JPEG images with the proper .jfif extension when the server omits the file name.
The solution is easy: either rename the extension from .jfif to .jpg, or use a converter tool to create a properly labelled JPG photo. Either way, the image data stays the same.
The easiest method is a direct file rename. For Windows users, enable file extension display in File Explorer, click here right-click the .jfif image, select Rename and modify the extension to .jpg.
