Have you ever saved an photo from the web and discovered it downloaded with a .jfif extension instead of the expected .jpg, you are not alone. JFIF — which stands for JPEG File Interchange Format — is a specification defining how JPEG images is stored.
In practical terms, a JFIF file is a JPEG photo. The .jfif file type shows up mainly after saving images from certain browsers, mainly when files are comes lacking a specific content-type header.
JFIF files started showing to regular users here since some browsers — mainly previous versions of Internet Explorer — save JPEG files with the correct .jfif extension when websites fails to specify the filename.
The fix is simple: just rename the file extension from .jfif to .jpg, or run it through a conversion tool to create a properly labelled JPG image. In both cases, 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, select Rename and update the extension to .jpg.
