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 — which stands for JPEG File Interchange Format — is a standard that defines the way JPEG photos is saved.
Simply put, a JFIF file is a JPEG image. The .jfif extension occurs mainly after saving images from certain browsers, mainly when files are comes lacking a specific content-type header.
JFIF files appeared to regular users because some older browsers — especially older versions of Microsoft Edge — download JPEG photos with the technically accurate .jfif file extension if the server does not specify the download name.
The solution is easy: check here either rename the extension from .jfif to .jpg, or use a converter tool to create a properly labelled JPG photo. Either way, the photo content remains unchanged.
The simplest approach is a file extension change. On Windows, activate showing file extensions in File Explorer, right-click the .jfif image, choose Rename and update the file extension to .jpg.
