Many users have saved an picture from the web and noticed it saved with a .jfif suffix instead of the usual .jpg, you are not alone. JFIF — short for JPEG File Interchange Format — is a format that defines how JPEG images is encoded.
In practical terms, a JFIF file is a JPEG file. The .jfif file type appears primarily after saving photos from specific browsers, mainly when the image was served without a defined file type header.
JFIF files started showing to most people as some older browsers — mainly previous versions of certain browsers — store JPEG photos with the correct .jfif extension when the server does not specify the filename.
The fix is simple: just rename the extension from .jfif to .jpg, or use a online converter to produce a more info standard JPG image. In both cases, the image data stays the same.
The quickest fix is a simple rename. On Windows, turn on showing file extensions in File Explorer, right-click the .jfif image, select Rename and update the extension to .jpg.
